Abstract

Laboratory-based PPS models with various surfaces were monitored for 3 years to assess their pollutant-retention and degradation capabilities. Road sediment (RS) and unused oil were applied to their surfaces and artificially rained on. Effluent water quality was found to be better than WHO (2011) potable water guidelines. A core taken of a porous asphalt rig found most of the contaminants remained in the surface course, lower than the original RS, suggesting some metals had migrated down through the rig. Aggregate-associated sediment provided secondary binding sites for dissolved metals; high numbers of bacteria found in the aggregate may further break down hydrocarbons and trap pollutants.
