On the basis of laboratory and in-situ tests, performances of Drainage Asphalt Pavement (DAP) were analyzed and compared with Anti-Skid (AK), Stone Asphalt Concrete (SAC) and Stone Mastic Asphalt (SMA) pavements. The analyzed performances included drainage, physical and mechanical, skid resistance and noise reduction properties. It shows that permeability coefficients of DAP (air voids is 17%–23%) are greater than 2.0 x 10–2cm/s and 2000ml/min, which is far more than that of dense asphalt pavements. Its high-temperature stability, low-temperature crack resistance, skid resistance and noise reduction are excellent because of its large air voids and modified asphalt, but its water stability and anti-fatigue performances are not good enough. As a result, most of the performances of DAP are better than dense asphalt pavements except water stability and anti-fatigue performances.
