摘要
在明确路表径流污染主要评价指标的基础上确定了可减少路表径流量的沥青混合料的目标空隙率,继而从多孔沥青混合料组成设计出发,研究不同空隙结构沥青混合料控制径流污染的效能和力学性能,从而提出多孔沥青混合料材料设计要点,为设计生态环保型透水路面提供参考.
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.
