%X Runoff samples from two pavements with different materials during the three rain events in 2010 in Chongqing were collected and determined. The characteristics and differences of runoff pollution on asphalt pavement and concrete pavement were investigated. The results showed that the event-mean concentrations of chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) exceeded the environmental quality standard of Class V surface water. The concentrations of total suspended substances (TSS), COD and TP from the runoff on asphalt pavement were 2.05, 1.35 and 1.27 times higher than that on concrete pavement, respectively. The initial concentrations of pollutants on asphalt pavement were higher than those on concrete pavement, and the maximum concentrations of TSS and TP on asphalt pavement appeared later than those on concrete pavement. During the three rainfall events on June 19, July 4 and July 9 in 2010, the average values of the ratios of 30% runoff amount to the concentration of the pollutant in runoff (FF30) on asphalt pavement were 1.26, 1.07 and 1.32 times that on concrete pavement, respectively. Differences in number of dents and chemical compositions of the pavements were the two major causes for the differences of runoff pollution.
