Results from first Danish full scale test section with poroelastic road surface

Résumé

The first Danish test section with poroelastic road surface (PERS) was constructed on August 27th 2013 at the Kalvehave test site in Denmark, as a part of the EU project PERSUADE. The test section is 75 m long and has the width of one driving lane. The yearly daily traffic is 4000 with 10 % heavy vehicles. The speed limit is 80 km/h and the estimated real speed is somewhat lower. The pavement is optimized for low emission of tyre-road noise by using a high built in air void, small aggregates and elastic material. The pavement has a porous structure and is composed of stone and rubber aggregates with a maximum aggregate size of 5 mm and the binder used is polyurethane. The pavement type has been developed and tested in the laboratory. An intensive monitoring program was started at the Kalvehave test site even before the test section was opened for normal traffic. The monitoring program includes measuring noise, acoustical absorption, elasticity, permeability, friction, rolling resistance and visual inspections. Measurements of noise using the SPB road side and the CPX trailer methods have been repeated continuously over the first 9 months of the lifetime of the PERS pavement.
