摘要
为探讨新型路面材料对路面径流污染的净化功效,对哈尔滨嵩山路路段路面径流排水进行取样分析。结果表明,透水沥青路面对径流污染因子COD、SS、浊度、Pb、Zn均有良好的净化作用。其净化有效空隙率范围为12.1%～23.0%。掺混陶粒率为40%的透水沥青路面对径流污染的净化功效明显优于纯沥青路面。
In order to investigate the purification effect of new type permeable asphalt pavement material on runoff pollution, storm water samples collected from Songshan road in Harbin were determined. The results showed that the pervious asphalt pavement had good purification effect on the COD, SS, turbidity, Pb and Zn in the effective porosity of 12.1%-23.0%, in addition, the purification effect of pervious asphalt pavement intermingled with 40% ceramsite on runoff pollution was much better than that of groundmass pavement.
