Abstract
In order to improve the anti-flying performance of pervious asphalt concrete,the asphalt concrete specimens with different voids,ag-gregate gradations and asphalt materials were tested and analyzed.The results show that the high temperature stability,water stability and flight resistance of pervious asphalt concrete under different conditions are evaluated comprehensively,and the optimal voidage of the mixture is 22%.Although higher voidage can improve the high temperature stability of concrete,it can also weaken the water stability and flight resist-ance.Compared with PAC13-1,the residual stability of PAC13-6 is reduced by 7.92%,and the flight loss rate is increased by 129.30%.In addition,the use of high viscosity modified asphalt can significantly improve the overall performance of pervious asphalt concrete.关键词
