    Dimensionering vid nybyggnad: utformning av ett användarvänligt mekanistiskt/empiriskt dimensioneringssystem för svenska förhållanden1996Report (Other academic)
    Abstract [en]

    Pavement design means selecting materials and determining layer thicknesses so that the road fulfils the performance requirements for a chosen period. Mechanistic design methods make it possible to adapt designs to the particular conditions. The need for a flexible design system is motivated by the development of vehicles and especially tyres (increased inflation pressure and wide base tyres). In recent years, development has taken a direction that is unfavourable in regard to road wear.

    An expected increase in usage of secondary and recycled road materials in the future is a further motive for a flexible design system. Work on developing a flexible design system for Swedish conditions has been commissioned by the Swedish National Road Administration and was carried out during the period 1987-1994. The result is described in this report. The aim of the project was to develop a user-friendly and flexible design system for road pavements which is suitable for Swedish conditions.

    The following three principle sections are required for the calculation of the bearing capacity of road pavements based on a mechanistic approach:

    •- A calculation method for the determination of stresses and strains in the road structure.

    •- Knowledge of the mechanical properties of the road building materials and of the subgrade, primarily stiffnesses or resilient moduli.

    •- Design criteria or design values for the stresses and strains that are critical for the bearing capacity of the road structure.

    Restvärde hos vägar: en kunskaps- och idesammanställning kring hur investeringar ska styras för lägre LCC2011Report (Other academic)
    Abstract [en]

    This report deals with a concept applying residual value estimations to applications in optimisation and procurement of road construction and maintenance. The purpose is to develop a framework and concept for tieing together technical and economical considerations in order to contribute to more optimised construction and maintenance of roads in a long-term perspective. This report is limited to investments in the pavement. Initially, the term residual value and its application in this context is investigated. Then, possibilities for prediction of pavement deterioration and performance are presented. These models are also linked to prediction of maintenance needs. Finally, a concept for cost predictions is developed with corresponding residual value applications, for example performance procurement, payment models, as well as more optimised pavement management from a life cycle perspective.

    Influence of pavement materials on field performance: Evaluation of rutting on flexible semi-rigid and rigid test sections after 7 years of service2009In: International Journal on Road Materials and Pavement Design, ISSN 1468-0629, E-ISSN 2164-7402, Vol. 10, no 4, p. 689-713Article in journal (Refereed)
    Abstract [en]

    This paper presents results obtained so far from a Swedish full-scale test, comprising in total 19 different rigid, semi-rigid and flexible test stretches. The purpose is to compare rutting performance of the different pavement categories and types using extensive laboratory tests and field measurements after seven years of trafficking. The rigid pavements withstand rutting better than the two other pavement categories due to comparably small abrasion and negligible permanent deformation. The semi-rigid pavements show less rutting than the flexible pavements, which primarily is the result of the negligible permanent deformation in the cement bound layers. Even though the rigid pavements show very small rutting, it is probably not the main distress type and the primary trigger for maintenance activities for this pavement type. In the case of semi-flexible and flexible pavements, both laboratory tests and field measurements indicate that significantly improved rutting performance can be obtained using appropriate asphalt mixtures manufactured using wear-resistant aggregates and stiff binder.

    Funktionsupphandling: sammanfattning av kunskapsläge och rekommendationer för fortsatt forskning2006Report (Other academic)
    Abstract [sv]

    The Swedish concept "procurement of function" corresponds to performance contracting in Anglo-Saxon countries. The substance is that principal and agent signs a contract over the construction and maintenance of a specific project based on the services provided to future users, i.e. based on performance of the asset. This is in contrast with contracting base on technical qualities of the new road. VTI has reserved funds to provide an overview of current knowledge in this context. Four separate contributions, together with a short summary, are included in this report. One conclusion is that the experiences of this contractual form are much larger in other countries than in Sweden. We therefore have a lot to learn, not least from our closest neighbours Finland and Norway. International experiences indicate a large and growing interest in this form of contracting and provides reason for further development. A second conclusion is that Sweden in general and VTI in particular has important information of direct relevance for the development of efficient performance contracts. This knowledge must, however, typically be structured and organised along other lines than when the original research was undertaken. The institute should therefore seek to adapt the collection of information of relevance for performance contracts so that it fits in to this new framework. This includes issues such as the measurement of road surface quality and assessment of the additional costs for providing better surface quality on the one hand and the user benefits of improved quality on the other.

    Accelerated load testing of pavements: HVS-NORDIC tests at VTI Sweden 2003-20042006Report (Other academic)
    Abstract [en]

    During 2003 and 2004 two accelerated load tests were performed at the VTI test facility in Sweden (SE05 and SE06). The objective of SE05 was to investigate the deformation behaviour of two different unbound base materials. Half of the test area was constructed with a base layer of natural granular material and the other half with a base layer of crushed rock aggregate. This means that the two structures were tested simultaneously. The objective of SE06 was to be the third test in a series of structural design tests with stepwise higher bearing capacity. The previous two tests in this series are SE01 and SE02. In the unbound base material test, SE05, the surface rut depth propagation during the accelerated load testing was greater on the crushed rock aggregate structure especially in wet condition. This was not expected and more than half of the difference in surface rut depth was found in the difference in the base layer deformations. One main reason for this unexpected behaviour is believed to be unsatisfactory compaction of the crushed rock aggregate. The performance of the pavement structures SE01, SE02 and SE06 during the accelerated load testing will be analysed in more detail in the future. One preliminary conclusion is that there seems to be a fairly strong correlation between the rut depth propagation in dry condition and surface deflections from falling weight deflectometer (FWD) measurement on these three structures with gradually increasing bearing capacity.

    Accelerated load testing of pavements: HVS-NORDIC tests in Sweden 19992001Report (Other academic)
    Abstract [en]

    In 1997 Finland and Sweden jointly invested in a Heavy Vehicle Simulator, HVS, from South Africa. After the first period in Finland the HVS-NORDIC was moved to Sweden and VTI (Swedish National Road & Transport Research Institute) in Linkoping in September 1998.

    A program for research co-operation in the area of accelerated pavement testing has been agreed between Finland and Sweden covering the years 1997-2003.

    The general objective of the research co-operation is to learn more about pavement response and pavement performance. A second but most important objective is to learn about the HVS-machine itself and the way it simulate traffic and deteriorate pavements and how this is related to real pavement performance.

    During the first year in Sweden, 1999, tests were performed as planned in the research program on typical Swedish low volume road structures. The results from these tests are presented in this report.

    The HVS-NORDIC is a mobile linear full-scale accelerated pavement-testing machine (HVS Mark IV). At VTI there is an indoors full-scale pavement test facility where pavements can be constructed by ordinary road construction machines.

    During the first year in Sweden four structures were tested. The first two tests (SE01 and SE02) were performed on newly built pavements (gravel/bitumen type with thin asphalt surface layers) while the other two were performed after rehabilitation of the first two after completed tests. The rehabilitation measure was milling and levelling (overlay in the milled area) of the surface layer to get a new even surface without rutting.

    The results evaluated in this report are the results from the pavement performance measurements, (rutting and deformation). A large amount of data has been collected during the pavement response measurements. These data, stresses, strains and deflections during a variety of test conditions will be used later for comparison of the test structures and for analysis of relations between pavement response and pavement performance.

    Accelererad provning av vägkonstruktioner: med och utan polymermodifierat bitumen i bindlager2010Report (Other academic)
    Abstract [en]

    In this report, a full-scale test, SE09, is described. The test was performed through accelerated testing using the HVS (Heavy Vehicle Simulator) in the road laboratory at the VTI. Full-scale road structures were constructed in the laboratory on a subgrade of fine graded sand, and accelerated loading was carried on by the HVS using a truck wheel. Totally, together 0,5 million loadings were carried on in three different pavement temperatures (+10°C, +20°C and +30°C) under the period of December 2004 to March 2005. The aim of the test was to study the stability characteristics of two pavement structures with different binder courses in relatively thick bitumen pavements in different temperatures. In one of the structures, polymer modified bitumen was used in the binder course, and in the other a conventional bitumen (ABb22, 70/100, according to the Swedish ATB Väg).

    Accelererad provning av vägkonstruktioner: referensöverbyggnad enligt ATB Väg2010Report (Other academic)
    Abstract [en]

    In this report, two full-scale tests (SE10 and SE11) are described that were performed under the same test conditions in order to investigate the accuracy of repeated tests. The tests were performed by accelerated loading using the HVS (Heavy Vehicle Simulator) in the road laboratory at the VTI.

    The purpose of performing two tests with the same kind of road structures, i.e. a reference construction according to the Swedish Road Administration's ATB Väg, under the same test conditions was to get to know the accuracy of the test results from repeated test. This was made in order to be able to make demands on the results of corresponding HVS-tests of road structures that don't follow the specifications of the Swedish Road Administration, for example alternative road structures in cases of side tenders contracts.

    The results presented in this report are the results from surface rut depth measurements, permanent deformations in different layers and total deformation of the subgrade during the tests as well as falling weight deflectometer measurements before and after the tests. The results of the response measurements (stresses, strains and deflections) are stored in an Access database for later analyses.

    The results of rut depth measurements show a relatively large difference in rut depth growth on the surface during the second phase (in wet condition) of the two tests. In two out of five measurement positions there was correspondence, whereas in the three other measurement positions there was a larger rut depth concerning SE11. The deviation could be referred to the rut depth growth during the first days in wet condition but some clear reason has not been able to be determined.

    Prov med olika överbyggnadstyper: observationssträckor på väg E6, Fastarp-Heberg. resultatrapport efter 7 års uppföljning, 1996-20032005Report (Other academic)
    Abstract [sv]

    I samband med utbyggnaden av väg E6 norr om Halmstad, delen Fastarp-Heberg, valde Vägverket att utföra överbyggnader med olika konstruktiv utformning. VTI har på uppdrag av Vägverket Västra regionen dokumenterat byggandet och följt tillståndsutvecklingen på speciellt utvalda observationssträckor. Vägavsnittet, som är totalt ca 21 km varav 1/3 är utförd med bituminös beläggning och 2/3 med cementbetongbeläggning, öppnades för trafik den 13 november 1996. I föreliggande rapport redovisas resultatet av tillståndsuppföljningen under de sju första åren efter trafikpåsläpp. Uppföljningen är planerad att pågå ytterligare tre år. Så här beskriver Vägverket Västra regionen bakgrunden till provvägen: "Det svenska vägnätet har successivt belastats med allt större laster. Regelverken för utförande har förnyats med jämna mellanrum bl.a. för att konstruktionerna skall klara lasterna. Under ett flertal år har nybyggda vägar utförts som asfaltkonstruktioner. Under senare delen av 1980-talet beslöts att utföra någon nybyggd väg med betongöverbyggnad. De vägar som utfördes med betong var E4 vid Arlanda och E6 söder Falkenberg. Då det stod klart att E6 Fastarp-Heberg skulle byggas ut till motorväg tog regionchefen i västra regionen beslut att detta objekt skulle utföras som provväg dels med betongöverbyggnad dels med asfaltöverbyggnad. Huvudsyftet var att kunna jämföra de olika konstruktionerna mot varandra i ett långsiktigt perspektiv. Det förväntade resultatet är att kunna redovisa säkra skillnader mellan de olika konstruktionerna beträffande: stabilitet, spårslitage, deformationsresistens, underhållskostnader, friktion och buller. Den förväntade nyttan är att med en väl underbyggd uppföljning från projektet kunna planera och investera med de för ändamålet rätta tekniska lösningarna framförallt på de bundna överbyggnadslagren."

    Prov med olika överbyggnadstyper: uppföljning av observationssträckor på väg E6, Fastarp-Heberg. 1996-20062009Report (Other (popular science, discussion, etc.))
    Abstract [en]

    In connection with the construction of a new part of European road 6 (E6) close to the city Halmstad, (section Fastarp-Heberg), the Swedish Road Administration decided to investigate the long term behaviour of different types of pavement structures. VTI got the mission to make documentation during the construction and to follow-up the performance of these pavement structures on selected sections. The total length of this new road was 21 km and 1/3 was constructed with flexible pavement structures and 2/3 with rigid pavement structures (cement concrete). The road section was open to traffic in the autumn 1996. The main objective of the study is to investigate the pavements resistance to rutting, both regarding wear from studied tires and deformation from heavy traffic. The objective is also to study surface characteristics as evenness, friction and noise. This report includes results and analyses from the first 10 years of the study (1996-2006). In summary the conclusions so far are as follows: - Performance based specifications clearly improved the deformation properties of the bituminous bound layers. - Semi-rigid pavement structures showed good resistance to rutting. - Investigation is needed to improve the resistance to reflective cracking of the semi-rigid structures - The vertical position of steel net in reinforced flexible structures is important. A position below a thin wearing course (40 mm) can not be recommended from this study. - More than half of the surface rutting on the flexible structures could be referred to deformation from the heavy traffic and a great deal occurred after the first year. - Rigid pavement sections showed good wear resistance. - The difference in surface friction and noise was small between flexible and rigid pavement sections but regarding noise this was only followed during the first three years of the study.

    Abstract [sv]

    I samband med utbyggnaden av väg E6 norr om Halmstad, delen Fastarp-Heberg,

    valde Vägverket att utföra överbyggnader med olika konstruktiv utformning.

    VTI har på uppdrag av Vägverket Västra regionen dokumenterat byggandet och

    följt tillståndsutvecklingen på speciellt utvalda observationssträckor.

    Vägavsnittet, som är totalt ca 21 km varav 1/3 är utförd med bituminös

    beläggning och 2/3 med cementbetongbeläggning, öppnades för trafik den 13

    november 1996. I föreliggande rapport redovisas resultatet av

    tillståndsuppföljningen under de fem första åren efter trafikpåsläpp.

    Uppföljningen är planerad att pågå ytterligare två år. Så här beskriver

    Vägverket Västra regionen bakgrunden till provvägen: "Det svenska vägnätet

    har successivt belastats med allt större laster. Regelverken för utförande

    har förnyats med jämna mellanrum bl.a. för att konstruktionerna skall klara

    lasterna. Under ett flertal år har nybyggda vägar utförts som

    asfaltkonstruktioner. Under senare delen av 1980-talet beslöts att utföra

    någon nybyggd väg med betongöverbyggnad. De vägar som utfördes med betong var

    E4 vid Arlanda och E6 söder Falkenberg. Då det stod klart att E6

    Fastarp-Heberg skulle byggas ut till motorväg tog regionchefen i västra

    regionen beslut att detta objekt skulle utföras som provväg dels med

    betongöverbyggnad dels med asfaltöverbyggnad. Huvudsyftet var att kunna

    jämföra de olika konstruktionerna mot varandra i ett långsiktigt perspektiv.

    Det förväntade resultatet är att kunna redovisa säkra skillnader mellan de

    olika konstruktionerna beträffande: stabilitet, spårslitage,

    deformationsresistens, underhållskostnader, friktion och buller. Den

    förväntade nyttan är att med en väl underbyggd uppföljning från projektet

    kunna planera och investera med de för ändamålet rätta tekniska lösningarna

    framförallt på de bundna överbyggnadslagren."
