Safe, silent road surfaces
Due to the need to decrease traffic noise, various new road surface materials have been developed. In The Netherlands 25 per cent of the population is severely hindered by traffic noise. Therefore porous asphalt, two-layer porous asphalt and texture-optimised dense and semidense asphalt mixes have been applied on various locations in order to minimise tyre excitation and air-pumping and optimise absorption. The best performing surfaces are made of porous asphalt mixes having small maximum grain sizes like 2/6 or 4/8 millimetres. Noise reduction levels up to 7dB(A) relative to Dense Asphalt Concrete 0/16 have been reached. However there are some aspects that need further attention, like skid resistance and structural durability. Porous mixes show a lower resistance to ravelling and with other gap-graded mixes lower skid resistance. The paper describes skid resistance behaviour of various low noise surfaces.
