Study on the Influence of Active Rubber Powder Content on the Performance of Modified Asphalt Pavement
In order to improve the road performance of rubber powder modified asphalt,this article uses frying waste oil to activate the waste tire rubber powder,and studies the comprehensive performance of modified asphalt under different dosages of activated rubber powder.It is compared with the unmodified rubber powder modified asphalt.The results showed that activated rubber powder modified asphalt activated by frying waste oil can significantly improve the high-temperature stability,low-temperature crack resistance,elastic recovery,and construction workability of rubber powder modified asphalt;When the amount of activated rubber powder reaches 20%,the comprehensive road performance of modified asphalt is optimal.Therefore,activated rubber powder modified asphalt can provide a better choice for road surface construction.
