形成蓄水对彩色透水沥青路面性能影响的研究

Study on the Influence of Water Storage on the Performance of Colored Pervious Asphalt Pavement

通过建立试验模型,针对形成蓄水时,雨水在彩色透水沥青面层滞留时间的变化情况,研究其在不同雨水滞留时间和不同水的作用方式的情况下,路面性能的变化情况及性能变化的机理。结果表明,透水性沥青路面形成蓄水后,雨水滞留时间大幅增加,且雨水滞留时间增加会影响路面的抗水损害能力、水稳定性和抗飞散能力,雨水滞留时间越长,影响越大。

By establishing a test model, the variation of the retention time of rainwater on the water storage pavement was studied,and the change of pavement performance under different storage time was studied.The results show that after the water-permeable asphalt pavement is filled with water,and the rainwater retention time increases greatly,which will affect the performance of the pavement.The longer the rainwater residence time,the greater the impact.
