In the PERSUADE project, a consortium of twelve partners is working on the development of the poro-elastic road surface (PERS). The aim is to obtain a road surface which is extremely noise reducing (up to 12 dB(A) with respect to DAC), reasonably durable, safe for the traffic, environmental friendly and affordable. A poro-elastic road surface contains a large percentage of rubber (recycled tyre granules or fibers), (possibly) mineral constituents (stone aggregates and/or sand), glued together with a polymer glue (usually PUR). Several application modes will be tested (prefabricated mats, on site construction, the Rollpave concept and sets with a PERS layer on top.
