Porous Asphalt Design Based on Decreasing Runoff Pollutant

Abstract:

The evaluation index of runoff pollutant is first determined, and then the target air void of asphalt mix is ascertained to decrease the runoff quantity. From the prospect of porous asphalt composition design, a study is made of different structures of porous asphalts to assess the mechanical properties and surface run off control. At last, the key issues for porous asphalt design are proposed, which provides a reference for the eco friendly porous asphalt mix design and construction.
