DURAPAV (Durability of pavements that reduces noise and rolling resistance) (DURAPAV (Durability of pavements that reduces noise and rolling resistance))

Sponsors, duration, budget: NordFOU ; 2016-01-01 -- 2018-12-31 Subject(s): Abstract: The DURAPAV project will investigate durability of rolling resistance and noise reducing pavements through accelerated testing. The circular testing facility at VTI is seen as excellent equipment for performing accelerated testing, which can identify potential weaknesses and predict pavement failure. The DURAPAV project will, based on the accelerated tests, seek to enhance the durability for pavement types with low rolling resistance and noise properties by optimizing the polymer distribution and mixture adhesion of the asphalt material. As the pavements need a small texture depth to provide lower rolling resistance and reducing noise, there is a potential risk of skidding problems and other surface defects. The mix design is therefore a delicate matter to secure all functional properties for the entire life time of the pavement. A lifetime that needs to be comparable with the life time of traditionally used wearing courses of 12 – 15 years. Denmark, Faroe Island and Sweden participate in this project.
