Accelererad provning av vägkonstruktioner: med och utan polymermodifierat bitumen i bindlager

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).
