Two-layer porous asphalt

Areas of Expertise (1)


Core Tasks (1)


This project originated from the search for an alternative to conventional porous asphalt, which, while retaining the many advantages (acoustic properties, drainability, skid resistance, resistance to rutting) of this type of mixture, was required to reduce or limit its disadvantages (winter behaviour and durability).

As a complement to some research in the laboratory, a test section was constructed in 2002 following a rehabilitation project initiated by the then Walloon public service (SPW). Research report CR41/06 presents the results of the observations and measurements made during the preparation of the experiment and the construction and monitoring of the test section, as well as a few recommendations for future applications.
