Flush Rule and Initial Flush Analysis of Cement Concrete Pavement

Abstract:

Road runoff was the major contribute to water body pollution. According to the cement concrete pavement flush was evaluated by artificial rainfall model, the experiment indicated that the runoff coefficient of cement concrete pavement was 0.85, the flush coefficient of dissolvable pollutant of road runoff flush model k was 0.082, and the flush coefficient of indissolvable pollutant of road runoff flush model k was 0.057. With the increasing cumulate runoff ratio, the initial flush coefficient k_n was decreasing. The emission of 90% dissolvable pollutant and of 30% indissolvable pollutant was removed by 30% runoff.
