| 摘要： | A water supply and water distribution system were designed and constructed to simulate rainfall on 50 ft by 20 ft asphalt and concrete pavements. A water collection system was also designed and constructed to collect the runoff from the pavements. The entire system was designed in a manner so that it can be mounted on a truck and ported to other locations. A total of 64 experiments, many of which were duplicated, were conducted on the pavements and the data were analyzed to determine the curve number for asphalt and concrete. The effects of pavement slope, rainfall intensity, and rainfall duration on the curve number value were examined. It was determined that the curve number for concrete is essentially 100 and its value for asphalt ranges from 97 to 100. |
