Research on Characteristics of Rainwater Runoff on Concrete Pavement
collecting rain water for ut ilization is the key to enhance the utilization efficiency of urban road rainwater.The road runoff charact eristics as water harvesting surface plays an import ant role in the collection and utilizat ion of rainwater.This art icle uses t he art ificial concrete surface to simulate road surface for the research on concrete pavement runoff charact eristics.Threshold rainfall of t he concrete pavement without antecedent rainfall is found to be 1.5 mm.Only if the rainfall amount approaches 1.5 mm
the rain water collection surface will have runoff.Road runoff coefficient increases with the increasing of rainfall amount.Runoff intensity islagging and weak in comparison with rainfall intensity.
