Long-term performance study of different pavement structures : A ten year study of flexible, semi-rigid and rigid pavement structures, 1996-2006 (English)
Abstract [sv]

I samband med utbyggnaden av väg E6 norr om Halmstad, delen Fastarp–Heberg, valde Vägverket att utföra överbyggnader med olika konstruktiva utformningar. VTI har på uppdrag av Vägverket Region Väst dokumenterat byggandet och följt tillståndsutvecklingen på speciellt utvalda observationssträckor. Vägavsnittet, som är totalt cirka 21 km varav 1/3 är utförd med bituminös beläggning (12 observationssträckor) och 2/3 med cementbetongbeläggning (7 observationssträckor), öppnades för trafik den 13 november 1996. Huvudsyftet med provvägen är att studera de olika överbyggnadstypernas förmåga att motstå spårbildning, både med avseende på dubbdäcksavnötning och med avseende på deformation från den tunga trafiken. Vidare är syftet att studera jämnhet i längdled och de olika slitlagertypernas egenskaper med avseende på friktion och buller. I denna rapport redovisas resultat och analyser av tillståndsuppföljningen under de tio första åren efter trafikpåsläpp (1996–2006).

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.
