    Main Report on Results of Comparative Site Monitoring2012Report (Other academic)
    Abstract [en]

    The objective of WP 2 is to analyse the potential use of reclaimed asphalt (RA) in new asphalt surface layer mixes and particularly the use of modified binders. Therefore the chemical compatibility of new binders with old bitumen in RA and the physical performance of the resulting binder and asphalt mixes have been examined separately to develop mix-design guidelines to ensure a long service life of asphalt mixes with reclaimed asphalt.

    In new bituminous bound courses, especially in base asphalt layers, the use of up to 40 % of RA is state of the art in most of the European countries. In surface layers, RA is currently used in relatively small amounts (10 to 20 %) if at all, because the demands on the properties of surface courses are very high. Surface courses need good deformation resistance at high temperatures as well as a high resistance against top-down cracks at low temperature and good skid resistance. The aggregates and binder used in surface courses are therefore of premium quality.

    The objective of WP 2 is to analyse the potential use of reclaimed asphalt (RA) in new asphalt surface layer mixes including the use of penetration grade and polymer modified binders (PmB’s). In lower asphalt layers (e.g. bituminous base courses) the use of high quantities of RA is common in most European countries. In surface course layers this occurs less frequently due to the high demands on the surface course.

    Incorporation of RA into asphalt layers can reduce the demand for added binder to the new mixture, depending on the residual binder content and recovered binder properties of the RA. Using RA in new asphalt mixtures has the potential to reduce costs and reduce energy requirements through reduced demand for raw materials and reduced transport of raw materials. This report covers the performance RA sites monitored which include both plant mixed RA sites (with and without polymer modified binder); and in situ hot recycling sites. The performance of sites is compared with control sections where no RA has been used.

    The performance of a trial gravel road under accelerated pavement testing2016In: Transportation Geotechnics, ISSN 2214-3912, Vol. 9, p. 161-174Article in journal (Refereed)
    Abstract [en]

    This study presents the performance of a trial gravel road subjected to HVS (Heavy Vehicle Simulator) trafficking in a compressed time period. The road structure was constructed with 150 mm-thick aggregate base course, and 125 mm-thick sub-base course. The test road responses, such as surface deformation and rutting were recorded using laser profile measurement instrument while the unbound layers’ dynamic deflections and strains data were periodically recorded at different depths during the execution of the test by means of an array of micro strain gauges.

    The test road was also instrumented with Water Content Reflectometers to record the changes in moisture contents in the road layers caused by the raising of the water table level under HVS trafficking. A total number of 85,000 HVS passes were applied to the trial gravel road structure under near-optimum as well as partially submerged subgrade moisture conditions. The test results emphasize the fact that the partial soaking of the subgrade soil by raising the groundwater table level caused a serious damage to the tested gravel road, as further detailed in this paper.

    Effect of Groundwater Table Rising on the Performance of a Swedish- Designed Gravel Road2017In: Transportation Geotechnics Journal, ISSN 2214-3912, Vol. 11, p. 82-96Article in journal (Refereed)
    Abstract [en]

    Sweden has a wide network of gravel roads. When the water table levels rise during the freeze-thaw and wet seasons, the bearing capacity of the roads will decrease and rut depths increase. The road will suffer a small deterioration every time a vehicle travel over it. Therefore, it has been decided to investigate the long-term performance of a Swedish designed gravel road using an accelerated pavement testing facility.

    A trial gravel road was constructed and exposed to various levels of ground water table which simulate the weather changes in Sweden. The structure of the trial gravel road consisted of 15 cm (base and surface layer), 20 cm sub-base layer and 260 cm subgrade soil. The trial road was tested using the Heavy Vehicle Simulator (HVS) and the vertical surface deformations and the vertical dynamic deformations were measured by means of laser profile measurement and εMU coils respectively. At the end of 85 000 HVS passes, the tested road suffered from serious deformations as discussed in details in this paper. Furthermore, a transverse trench section was excavated at the end of HVS trafficking in order to investigate the possible mechanism contributing to the tested road failure.

    Cold recycling of asphalt at a central plant: follow up of test roads in Halland, Södermanland and Gävleborg counties2014Report (Other academic)
    Abstract [en]

    Cold recycling of asphalt is a resource-saving technology because the materials do not need to be warmed up. Moreover, by using this technique, up to 100 per cent reclaimed asphalt concrete (RA) could be recycled. However, in order to achieve good results, the old RA should be processed in a proper manner. The report presents results of tests carried out on road N-714, part Vessigebro–Ätrafors and road N 530, part Såghuset–Skönhult in Halland in addition to road D-976, Strängnäs and road D-957, Vansö in Södermanland. Moreover, this report presents results of tests performed on road X-583, part Ljusne–Sandarne in Gävleborg. The mechanical properties have been investigated by indirect tensile strength and stiffness modulus for RA mixtures and drill cores. The tests results showed that part of the damage that may be encountered when using cold recycled asphalt coatings can be in the form of loss of surface materials, mechanical damage due to relatively soft road surfaces and unevenness of the road surface.

    Effect of Compactive Effort on the Behaviour of a Gypsiferous Subgrade Soil2004Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Presented in this thesis is a study of the effect of compactive effort and long-term soaking on strength, stiffness and deformation characteristics of a gypsiferous subgrade soil from Kirkuk city.

    The tested soil is sandy lean clay (CL) according to the Unified Soil Classification System and A-6 (6) soil according to AASHTO soil classification system. The soil contains about 35% total soluble salts (T.S.S.) and about 33% gypsum.

    The compaction characteristics of the tested soil indicate that the AASHTO compaction curves are of double peaks having two maximum dry unit weights and two optimum moisture contents.

    To study the effect of compactive effort and long- term soaking on the properties of the tested soil, ninety-six CBR soil samples were prepared, fourty eight CBR samples for each moulding optimum moisture content of 2% (dry optimum moisture content DOMC) and 11.5% (wet optimum moisture  content WOMC). For each moulding moisture content and each soaking period of (0, 4, 7, 15, 30 and 120 days), eight CBR samples were prepared, two for each case of the four chosen compactive efforts of 12, 25, 56 and 70 blows/layer.

    Unconsolidated undrained and consolidated undrained triaxial tests (with pore water pressure measurements) were carried out on samples extracted from CBR samples as well as on samples compacted in manufactured mould at WOMC to determine the cohesion and friction of tested soil using the triaxial cell.

    For samples compacted at DOMC, various unconsolidated undrained shear box tests were carried out to determine c and ø of the tested soil.

    The full load-penetration curve obtained from CBR test was used to determine the resilient modulus. In addition, the ultrasonic tests were carried out on CBR samples to estimate the resilient modulus, and good agreement between both approaches was noticed especially for samples compacted at WOMC.

    Vertical swelling / settlement measurements were carried out on each CBR sample during soaking using 0.002 mm dial gauge.

    The moisture content determinations were carried out in this study to determine the effect of compactive effort on the distribution of moisture along the CBR soil sample during soaking of samples compacted at WOMC and DOMC. Similarly, the total soluble salts tests (T.S.S.) and the gypsum content tests were carried out for the same purpose.

    Abstract [en]

    A study of the strength characteristics of a fine-grained gypsiferous soil intended for use as a construction material for forming highway and airport embankments in desert areas is reported herein. The tested soil was a sandy lean clay (CL) according to the Unified Soil Classification System and an A-6 (6) soil according to American Association of State Highway and Transportation Officials (AASHTO) soil classification system, containing about 35% total soluble salts (TSS) of which 33% was gypsum. To study the properties of the tested soil, various California bearing ratio (CBR) soil samples were prepared at the dry optimum moisture content of 2% and soaked for 0, 4, 7, 15 and 30 days. The CBR tests revealed that there was a serious drop in the CBR due to soaking, which is in full agreement with the drop in c and f with soaking period, indicating that if gypsiferous soils are used as fill material they should be protected from ingress of water. To study the deformation properties of the tested soil, vertical swelling/settlement measurements were carried out on each CBR sample during soaking using a 0$002 mm dial gauge. The effect of soaking period on the distribution of moisture, TSS and gypsum content was also studied. It was observed that there was an increase in moisture content and a decrease in TSS and hence gypsum with increasing soaking for CBR samples compacted at the dry optimum moisture content.

    2005 (English)Conference paper, Published paper (Refereed)
    Abstract [en]

    Presented in this paper is a correlation between the bearing capacity of a gypsiferous subgrade soil with the corresponding CBR value. The geotechnical tests carried out on this soil indicate that the soil is sandy lean clay of CL group according to the USCS and A-6 (6) group according to AASHTO Soil Classification System. The soil contains about 33% gypsum content. For this purpose, thirty six CBR samples were prepared at optimum moisture content (of the modified AASHTO compaction test) namely 11.5% at compactive efforts of 1, 2 and 4.56 times that of the Proctor compaction (standard AASHTO). These samples were soaked for 0, 4, 7, 15, 30, and 120 days under the effect of 40 lbs (178 N) surcharge load. For each soaking period, three pairs of CBR soil samples were prepared, one for each compactive effort. The first CBR sample from each pair was used to determine the CBR value while the second CBR sample was used to obtain triaxial soil samples for unconsolidated undrained tests to arrive at the corresponding shear strength parameters. The present paper reveals that for each soaking period, there is a linear increase of the ultimate bearing capacity with increasing compactive effort, while a significant drop in the ultimate bearing capacity of the tested soil took place with increasing soaking period. The paper reveals also that there is a strong linear correlation between the estimated ultimate bearing capacity and the corresponding CBR value indicating that the Rosenak's equation correlating the bearing capacity with CBR value is very conservative.

    Abstract [en]

    Presented in this paper is a study of the effect of compactive effort (CE) and long-term soaking on the strength characteristics of a clayey gypsiferous subgrade soil. The tested soil is A-6 (6) soil according to American Association of State Highway and Transportation Officials (AASHTO) soil classification system. To study the effect of CE and long term soaking on the properties of the tested soil, various California bearing ratio soil samples were prepared and compacted at optimum moisture content of the modified AASHTO compaction, but using four different chosen CEs of 12, 25, 56 and 70 blows/layer and then soaked for 0, 4, 7, 15, 30 and 120 days. The California bearing ratio (CBR) tests indicate that the CBR increases significantly in a nonlinear manner with increasing CE for all soaking periods, indicating improvement in soil strength with increased compaction. The rate of increase dies out with increasing CE. The CBR tests reveal also that there is a serious drop in the CBR due to soaking for all CEs.

    Hot recycling of asphalt at a central plant: a general quality control process and long term follow up results: Swedish case studies2014Report (Other academic)
    Abstract [en]

    This notat aims to highlight the various demands on hot recycling of asphalt at a plant and to study how the recycled asphalt mixtures differ from the new one and how much asphalt granules that can be mixed without affecting the pavement performance negatively. The report presents a translation from Swedish to English of already published reports on hot recycling of asphalt in Sweden. Hot recycling at a central plant is a technique that has increased in popularity over the past years and today there are large numbers of asphalt recycling plants adapted for hot recycling in Sweden. In case of hot recycling plants, 10–50 percent of asphalt can be recycled depending on the plant type, method of recycling, type of the manufactured mixture, traffic volume and quality of the old asphalt pavement, etc. Recently, new recycling methods have been developed to enable 90–100 percent reclaimed asphalt (RA) involvement by continuous hot mix recycling. Correspondingly, the report presents results of tests carried out on the binder layer (ABb) of road 40 and surface course (ABS) of road 42, Västergötland. Research has been carried out on mixes and test sections to cover quality control of RA, stone materials in asphalt, binder content, particle size distribution and voids in asphalt, analysis of recycled binders and mechanical properties of asphalt.

    Improving low-volume road construction and performance: Validity of using the heavy vehicle simulator in evaluating the reinforcement of low-volume roads2013Report (Other academic)
    Abstract [en]

    VTI notat 9A-2013 highlights the benefits of using the heavy vehicle simulator (HVS) in verifying the validity of the proposed design of roads before construction which in turn leads to more efficient and economical road constructions. Sweden has a wide network of unpaved low-volume roads which suffer from frost-thaw problems as well as insufficient drainage. Geosynthetics are specially fabricated to be used in transportation engineering applications and to reduce the aforementioned roads problems. The validity of using geosynthetics as a cost-effective alternative for constructing unpaved roads could be examined by accelerated load testing. The use of geosynthetics in order to keep the shape and slope of subgrade soil as well as to stabilize the road structure is highly recommended to be examined in detailed under different loading and environmental conditions using the heavy vehicle simulator (HVS). This testing can result in significant cost and construction time saving, better and durable unpaved roads as well as encourage the use of geosynthetics in Sweden as a less expensive alternative in producing stable roads. In addition, the HVS can be used to evaluate the cost differences in conventional and new construction technique using the geosynthetic materials and to develop guidelines for road design and construction as well as to provide some input for the development of roads modeling software.

    Strong correlation between the laboratory dynamic CBR and the compaction characteristics of sandy soil2019In: INTERNATIONAL JOURNAL OF GEO-ENGINEERING, ISSN 2092-9196, Vol. 10, no 1, article id 7Article in journal (Refereed)
    Abstract [en]

    Construction of earth structures involves the use of compacted soils. In roads construction quality controls like the bearing capacity of the subgrade, base and subbase layers, CBR values and compaction characteristics are primarily important. In Sweden, it has become interesting to correlate new testing parameters collected by simple tests to the conventional compaction parameters collected from modified Proctor tests. This action will help in assessing the bearing capacity of the selected material simply and quickly using the recent developed techniques instead of the conventional techniques which have been considered as time consuming methods. The aim of this study is to demonstrate that the laboratory dynamic California bearing ratio (CBRLD) test can be used as a method of compaction assessment of selected subgrade soil. Moreover, it has been demonstrated in this study that the CBRLD can strongly be correlated to the compaction densities and molding water contents using polynomial correlation and a best-fit multiple regression model for a wide range of molding water contents. In addition, the repeatability of the dynamic laboratory CBR test was examined as discussed in the current article.

    Using of Circular Road Simulator to Evaluate the Performance of Asphalt Mixtures Made of Industrial By-Products2018In: Journal of Geotechnical and Transportation Engineering, JGTTE, ISSN 2379-8769, Vol. 4, no 1, p. 17-24Article in journal (Refereed)
    Abstract [en]

    It is well known that the use of by-products (recycled), instead of natural materials help toward more environmentally friendly roads by easing landfill pressures and reducing demand of extraction. Correspondingly, this paper deals with evaluating the mechanical performance of new developed hot mix asphalt (HMA) mixturesmade of alternative materials (up to 98% industrial wastematerials). The paper sheds light on the long-term performance of the new developed mixtures using the accelerated load testing facilities available at VTI (the Swedish National Road and Transport Research Institute). The materials, methods and results given in this article are part of ALTERPAVE European -project findings. In this project, different types of industrial by-products, namely, reclaimed asphalt pavement (RAP), foundry sand and steel slag) have been used in different fractions to find thecomposition of the best asphalt mixtures made mainly of industrial wastes that can substitute the asphalt mixtures made of natural aggregates. Using the circular road simulator (CRS), twenty- eight asphalt slabs were prepared using natural and industrial by-products and tested under different testing conditions. The CRS test has been used to assess the surface deterioration, wear and the changes in macrotextures of the tested asphalt slabs under wheel loading in dry or wet conditions and under different testing temperatures to simulate summer and winter seasons. In addition, studless and studded tires have been used to traffic the asphalt slabs during the CRS testing to simulate the current roads conditions in different European countries. The test results demonstrated that by controlling the homogeneity of recycled material and by using rejuvenators of suitable quality and quantity, it is possible to obtain paving mixtures with high content of recycled materials that can satisfactory substitute theconventional asphalt mixtures made of natural materials.

    Performance Assessment of Hot-Asphalt Mixtures Produced with By-product Aggregates under Repetitive Heavy Traffic Loading2019In: Journal of materials in civil engineering, ISSN 0899-1561, E-ISSN 1943-5533, Vol. 31, no 6, article id 04019088Article in journal (Refereed)
    Abstract [en]

    Given the importance of overcoming the challenges associated with the management of nonrenewable resources, and to solve the industrial waste stream problems, this article presents the results of fundamental research conducted to assess the rutting and fatigue cracking performance of hot asphalt mixtures with high percentages of by-product aggregates. For this purpose, two full-scale flexible pavement test sections were constructed and tested at the accelerated loading facilities at VTI (Swedish National Road and Transport Research Institute). The accelerated test aimed at evaluating the performance of two developed asphalt mixtures, designated as mix 1 and mix 7, and made up of 98% of industrial by-products (namely, steel slag, foundry sand (WFS), and reclaimed asphalt pavement, in addition to biobased additives). The test sections were constructed in an indoor facility and loaded with a heavy vehicle simulator (HVS) equipped with a half-standard truck axle with dual wheels. The two road sections were constructed using the same construction materials obtained from the same source, as follows: asphalt surface layer of 50-mm thick, 70-mm thick granular base layer, and 160-mm thick subbase layer on top of a 2.6-m thick sandy subgrade soil. Horizontal asphalt strain sensors were embedded in the pavement test sections to assess the mixture's resistance to fatigue and cracking and the laser surface profiler measurements were used to evaluate the rutting performance under controlled testing conditions. For comparison purposes, the long-term rutting developed in the sections paved with mix 1 and mix 7 was compared to the rutting observed in a previous similar HVS test carried out on a 70-mm thick asphalt surface layer section made only with natural virgin aggregates.

    The test results showed that mix 1 and mix 7 may suffer from higher rutting at the beginning when the road is open to traffic, as compared to asphalt mixtures of natural aggregate, but subsequently the alternative mixtures resisted the rutting development better with the increase of traffic loading as compared to the conventional asphalt mixtures. The horizontal strain measurements at the bottom of the asphalt layer during testing showed that failure began as cracks initiated at the bottom of the asphalt layer of mix 7 and started to propagate to the surface of the asphalt layer in the last stage of the HVS traffic loading of the test. No fatigue cracking was observed in the asphalt surface paved with mix 1 at the end of heavy vehicle simulation (HVS) testing. The study demonstrated that the adopted by-product hot mix asphalt (HMA) mixtures can substitute the conventional HMA material under the given heavy traffic loading and environmental conditions.

    Review on the effect of gypsum content on soil behavior2015In: Transportation Geotechnics, Elsevier publications, ISSN 2214-3912, Vol. 4, p. 28-37Article in journal (Refereed)
    Abstract [en]

    Increasing the utilization of urban soil usage brings along very important problems to be addressed at the international level regarding the use of sulfate bearing soils as construction materials. After briefly exploring current research perspective, this paper captures the current state of the art in the field of sulfate bearing soils used as construction materials through a detailed discussion of different studies that pave the way to the possible treatment of such soils to be used in road construction.Additionally, the purpose of this paper is to acquaint geotechnical and pavement engineers with the present state of the art of the physical and chemical properties of gypsum and hence its effect on the subgrade soil performance. On the other hand, this paper discussed an opposite action in which some researchers have mixed recycled waste gypsum components with soil in order to stabilize it. In other words, a number of open research issues are highlighted with the intension of inspiring new conditions and developments in stabilizing problematic gypsiferous soil as well as adding gypsum to stabilize non gypsiferous soils of weak performance.

    Evaluating the dynamic stabilities of asphalt concrete mixtures incorporating plasterboard wastes2015In: The international journal of pavement engineering, ISSN 1029-8436, E-ISSN 1477-268X, Vol. 16, no 10, p. 929-938Article in journal (Refereed)
    Abstract [en]

    This study aims at investigating the impact of recycling by-product plasterboard wastes (gypsum and bassanite) with asphalt mixtures by replacing partly the filler portion of the asphalt mixtures with pulverised plasterboard wastes in order to contribute to non-toxic and good urban environment on one hand and improve, or at least retain, the design mechanical properties of the resulting asphalt concrete mixture on the other. The study was based on series of wheel tracking tests which successfully proved the possibility of mixing recycled plasterboard wastes with asphalt mixtures. The tests results showed that asphalt samples of 40% gypsum-filler ratio and asphalt samples of 40% bassanite-filler ratio as well gave the maximum resistance to plastic deformations and hence maximum dynamic stabilities. As a result, this research has shown that mixing of plasterboard wastes with asphalt concrete mixtures in specific quantities is promising.

    Effect of Long-Term Soaking on the Distribution of Moisture and Total Soluble Salts in Compacted Gypsiferous Soils2001In: Iraqi Journal of Civil Engineering, ISSN 7428-1992, no 1, p. 263-271Article in journal (Refereed)
    Abstract [en]

    Presented in this paper is a study of the effect of long-term soaking on the distribution of moisture hence on the dissolution of total soluble salts (T.S.S.) and its distribution along compacted CBR samples of gypsiferous soil.

    The soil tested is a fat clay of CH grouping according to ASTM specification and A-7-6 (42) according to AASHTO soil classification system, with about 34.5 % T.S.S. and about 33 % gypsum content.

    For this purpose, sixteen CBR samples were prepared at 95 % relative modified AASHTO compaction and 17 % optimum moisture content. For each soaking period of 0,4,7,15,30,60,120 & 180 days, two samples were prepared and loaded by 40 lb (178N) surcharge load.

    The paper reveals that the moisture content along the CBR soil samples increased with increasing soaking period. This increase is more pronounced at the top of CBR soil samples than that at the bottom, while little increase in moisture content took place at the mid-depth of CBR samples even after 180 days soaking period. This phenomenon is in good agreement with the distribution of T.S.S. and gypsum content along the CBR soil samples for different soaking periods.

    An empirical equation is introduced in this paper that enables the determination of T.S.S. at the top of CBR samples after different soaking periods from the initial T.S.S. content.

    Effect of Soaking Period and Surcharge Load on Resilient Modulus and California Bearing Ratio of Gypsiferous soils2004In: Quarterly journal of engineering geology and hydrogeology, ISSN 1470-9236, E-ISSN 2041-4803, Vol. 37, p. 155-164Article in journal (Refereed)
    Abstract [en]

    A clay of CH group according to the unified soil classification system (or CV clay according to BS 5930) with about 33% gypsum content was tested in the laboratory for the resilient modulus using the ultrasonic wave propagation technique. Forty-eight California bearing ratio (CBR) soil samples were compacted at the optimum moisture content and 95% of modified AASHTO compaction. For each soaking period of 0, 4, 7, 15, 30, 60, 120 and 180 days, three pairs of samples were loaded at 45, 178 and 312 N surcharge load, respectively. The resilient modulus (MR of the gypsiferous soil tested was determined using CBR soil samples before and after each soaking period, and the following observations were made: (1) soaking results in a progressive decrease in MR with increasing soaking period; (2) after 180 days soaking the resilient modulus decreased by 92%, 85% and 80% relative to the unsoaked condition for CBR samples under surcharge loads of 45, 178, and 312 N, respectively. Furthermore, a strong linear correlation between the resilient modulus and soaked CBR was found. An empirical equation has been developed relating MR, at any soaking period to the unsoaked condition, taking into account the effect of soaking period and surcharge load.

    Modelling the Decrease of Total Soluble Salts of Clayey Soils during Long-term Soaking2012In: Quarterly journal of engineering geology and hydrogeology, ISSN 1470-9236, E-ISSN 2041-4803, Vol. 45, no 1, p. 111-118Article in journal (Refereed)
    Abstract [en]

    Presented in this paper is an experimental investigation into the effect of long-term soaking on the decrease of total soluble salts (TSS) contents and distribution of moisture for compacted clayey gypsiferous soil. Two types (A and B) of clayey gypsiferous soils were used in this study. For each soaking period, two California bearing ratio (CBR) samples were prepared of type A soil and soaked under 70 and 10 lb (312 N and 45 N) surcharge loads suitable for highways. Various CBR soil samples of type B were prepared and soaked under 210, 140 and 70 lb (935 N, 623 N and 312 N) surcharge loads (suitable for airports) for the same soaking periods as type A CBR soil samples. For long-term soaking periods, a gradual drop in TSS (mainly gypsum) content took place at the top of CBR samples to reach a significant amount at the end of 180 days soaking. An empirical equation has been developed relating the initial total soluble salts contents to the total soluble salts contents after various soaking periods of CBR soil samples in the laboratory, taking into account the plasticity properties of the tested soils and the effect of surcharge load.

    Predicting Long-term Soaked CBR of Gypsiferous Subgrade Soils2006In: Proceedings of the Institution of Civil Engineers: Transport, ISSN 0965-092X, E-ISSN 1751-7710, Vol. 159, no 3, p. 135-140Article in journal (Refereed)
    Abstract [en]

    Thirty-two laboratory California Bearing Ratio (CBR) tests were carried out on a CH gypsiferous subgrade soil with an initial gypsum content of 34%. The soil samples were prepared according to ASTM D 1883-99 at 95% of the maximum modified AASHTO dry density. For each 40 Ib (178 N) and 70 Ib (311-5 N) surcharge load, eight pairs of CBR samples were prepared, and soaked for periods of 0, 4, 7, 15, 30, 60, 120 and 180 days respectively. To develop a general empirical formula for predicting long-term soaked CBR from unsoaked CBR, use was made of available results on CH soil with a gypsum content of 15%, on granular gypsiferous soils of the SW-SM group with a gypsum content of 64%, and on SM soils with gypsum contents of 34% and 61%. The empirical equation developed in this paper enables the soaked CBR to be determined from the unsoaked CBR for all types of gypsiferous soil and for any surcharge load and soaking period. The equation's validity was examined using six different gypsiferous soils (eight case studies) including both granular and fine-grained soils. This paper also shows the invalidity of Fekpe's empirical equation in modelling the long-term behaviour of gypsiferous soils.

    Predictive Equation for Soaked CBR of a Clayey Gypsiferous Soil2002In: Engineering & Technology Journal, ISSN 1681-6900, Vol. 21, no 8, p. 603-610Article in journal (Refereed)
    Abstract [en]

    Presented in this paper is an empirical equation modelling the effect of long-term soaking on strength characteristics of a clayey gypsiferous subgrade soil.

    The soil tested is a fat clay of CH group according to the Unified Soil Classification System and A-7-6 (42) group according to AASHTO soil classification system. The soil contains about 34.5% total soluble salts (T.S.S) and about 33% gypsum content.

    For this purpose, forty two CBR samples were prepared at 95% relative modified AASHTO compaction. For each soaking period, six samples were prepared, two for each case of the three selected surcharge loads namely 10, 40 & 70 lb (44.5, 178 & 311.5 N). The soaking periods adopted in this study were 4,7,15,30,60,120, & 180 days.

    The empirical equation developed in this work enables the engineer to determine the soaked CBR from the unsoaked  one at any desired soaking period and under the effect of any surcharge load. Regression equations were developed to enable the determination of CBR under any surcharge load from the CBR under 10 lb (44.5 N) surcharge load for different soaking periods.

    Compaction and Design of Gypsiferous Fill for Hot Desert Road Pavements2011In: Proceedings of the Institution of Civil Engineers: Construction Materials, ISSN 1747-650X, E-ISSN 1747-6518, Vol. 164, no 1, p. 3-11Article in journal (Refereed)
    Abstract [en]

    A comparative study between a homogeneous road embankment constructed of gypsiferous soil and compacted throughout its full height at the dry optimum moisture content (DOMC) and an exactly similar embankment but with improved active zone (top 50 cm of the embankment compacted at the wet optimum moisture content WOMC), is presented. Two soils A and B were examined. Soil A was sandy lean clay (CL) containing about 35% total soluble salt (TSS) of which 33% was gypsum; soil B had a 28% TSS and a gypsum content of 25·6%. California bearing ratio (CBR) soil samples, prepared at DOMC and WOMC for soil A and at WOMC for soil B, showed serious reductions in soil strength and stiffness due to soaking, especially when the soil had been compacted at DOMC. A soaking period of 4 days was considered very reasonable and conservative for hot dry regions. Swelling of the soil during soaking was observed, especially when the soil was compacted at DOMC. For pavement design, it appears to be more economical to introduce an active zone compacted at WOMC instead of DOMC. The cost of the additional water required for compaction at WOMC instead of DOMC is much less than the savings in cost of sub-base material due to increased subgrade soil strength. It is concluded that the gypsiferous soil which occurs widely in the Middle East can be used to build embankments for hot desert road pavements.

    Improving Fine Grained Gypsiferous Soil by Increased Compaction2012In: The international journal of pavement engineering, ISSN 1029-8436, E-ISSN 1477-268X, Vol. 3, no 1, p. 32-38Article in journal (Refereed)
    Abstract [en]

    Presented in this paper is a study of the effect of compactive effort (CE) and long-term soaking on the strength characteristics of a clayey gypsiferous subgrade soil. The tested soil is A-6 (6) soil according to American Association of State Highway and Transportation Officials (AASHTO) soil classification system. To study the effect of CE and long term soaking on the properties of the tested soil, various California bearing ratio soil samples were prepared and compacted at optimum moisture content of the modified AASHTO compaction, but using four different chosen CEs of 12, 25, 56 and 70 blows/layer and then soaked for 0, 4, 7, 15, 30 and 120 days. The California bearing ratio (CBR) tests indicate that the CBR increases significantly in a nonlinear manner with increasing CE for all soaking periods, indicating improvement in soil strength with increased compaction. The rate of increase dies out with increasing CE. The CBR tests reveal also that there is a serious drop in the CBR due to soaking for all CEs.

    Strong Correlation between the Bearing Capacity and CBR of a Gypsiferous Subgrade Soil Subjected to Long-Term Soaking2005Conference paper (Refereed)
    Abstract [en]

    Presented in this paper is a correlation between the bearing capacity of a gypsiferous subgrade soil with the corresponding CBR value. The geotechnical tests carried out on this soil indicate that the soil is sandy lean clay of CL group according to the USCS and A-6 (6) group according to AASHTO Soil Classification System. The soil contains about 33% gypsum content. For this purpose, thirty six CBR samples were prepared at optimum moisture content (of the modified AASHTO compaction test) namely 11.5% at compactive efforts of 1, 2 and 4.56 times that of the Proctor compaction (standard AASHTO). These samples were soaked for 0, 4, 7, 15, 30, and 120 days under the effect of 40 lbs (178 N) surcharge load. For each soaking period, three pairs of CBR soil samples were prepared, one for each compactive effort. The first CBR sample from each pair was used to determine the CBR value while the second CBR sample was used to obtain triaxial soil samples for unconsolidated undrained tests to arrive at the corresponding shear strength parameters. The present paper reveals that for each soaking period, there is a linear increase of the ultimate bearing capacity with increasing compactive effort, while a significant drop in the ultimate bearing capacity of the tested soil took place with increasing soaking period. The paper reveals also that there is a strong linear correlation between the estimated ultimate bearing capacity and the corresponding CBR value indicating that the Rosenak's equation correlating the bearing capacity with CBR value is very conservative.

    Using Gypsiferous Soil for Embankments in Hot Desert Areas2008In: Proceedings of the Institution of Civil Engineers: Construction Materials, ISSN 1747-650X, E-ISSN 1747-6518, Vol. 61, no 2Article in journal (Refereed)
    Abstract [en]

    A study of the strength characteristics of a fine-grained gypsiferous soil intended for use as a construction material for forming highway and airport embankments in desert areas is reported herein. The tested soil was a sandy lean clay (CL) according to the Unified Soil Classification System and an A-6 (6) soil according to American Association of State Highway and Transportation Officials (AASHTO) soil classification system, containing about 35% total soluble salts (TSS) of which 33% was gypsum. To study the properties of the tested soil, various California bearing ratio (CBR) soil samples were prepared at the dry optimum moisture content of 2% and soaked for 0, 4, 7, 15 and 30 days. The CBR tests revealed that there was a serious drop in the CBR due to soaking, which is in full agreement with the drop in c and f with soaking period, indicating that if gypsiferous soils are used as fill material they should be protected from ingress of water. To study the deformation properties of the tested soil, vertical swelling/settlement measurements were carried out on each CBR sample during soaking using a 0$002 mm dial gauge. The effect of soaking period on the distribution of moisture, TSS and gypsum content was also studied. It was observed that there was an increase in moisture content and a decrease in TSS and hence gypsum with increasing soaking for CBR samples compacted at the dry optimum moisture content.
