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.

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.

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.

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.
