Abstract

Noise pollution is becoming a crucial problem in France as traffic is rapidly increasing. Therefore, quieter pavements are requested by many communities such as Limoges Metropole. The latter ordered the use of a low noise porous asphalt. This product is used as a wearing course. It is characterized by its phonic properties and improved skid resistance. However, due to its high content of voids (≥ 20%), its mechanical properties might not be as optimal as a conventional asphalt (BBSG: Semi-coarse asphalt concrete). Therefore, this work seeks to determine the durability of the requested porous asphalt experimentally. Tension/compression tests were carried out using samples cored from slabs. The experiments were performed for several temperatures (-10, 0, 10, 15, 20 °C) and frequencies (0.1, 0.3, 1, 3, 10 Hz). The results obtained show that the studied porous asphalt is a decent product compared to other asphalts.
