摘要
对废弃轮胎胶粉的酸值进行了测试 ,并据此进行了胶粉表面活化处理 ,再用作为沥青混合料的改性剂。用马歇尔试验、车辙试验和低温劈裂试验分别比较了活化胶粉与未活化胶粉改性后的沥青混合料性能变化。
The acid value of waste tire crumbs is tested, and the surface of crumbs are activated, then the crumbs are used as the modifier in asphalt mixture. When active crumbs are incorporated into asphalt mixture, Marshall test,wheel-tracking test and low-temperature split test are performed to evaluate the properties of them.
