摘要
花岗岩是酸性石料,与沥青的粘附性差,因而很少应用在沥青路面建设中。采用钛酸酯偶联剂改善花岗岩与沥青的粘附界面,通过花岗岩与沥青的粘附性试验、沥青混合料的浸水马歇尔试验及冻融劈裂强度试验,对花岗岩沥青混合料界面抗水损害能力进行了研究。研究结果表明,利用钛酸酯偶联剂能够明显提高花岗岩沥青混合料的水稳性能。
Granite is a kind of resourceful stone with high wearability and has poor adhesiveness. Therefore, granite is seldom used widely in asphalt pavement. In the experiments, the surface between granite aggregate and asphalt is modified by titanium ester coupling agent. Anti-water-damage ability of the asphalt mixture is experimented by the adhesiveness test, the soaking Marshall test and the freeze-thaw split strength test. The results show that the water stability can be improved obviously by titanium ester coupling agent.
