摘要
由于橡胶颗粒与沥青粘附性差,橡胶颗粒沥青混合料在实际应用中存在易剥落的现象,为了解决这一问题,采用适当的添加剂,如消石灰粉、水泥或者两者的混合物替代相等体积的矿粉,对集料及橡胶颗粒进行碱化处理,本文通过室内试验以选取最佳抗剥落剂,并进行路用性能验证。
Because of the poor adhesion between rubber particles and asphalt,the actual application of rubber particles mixed with asphalt has easy peeling off pheno-menon. To solve this problem,we can use appropriate additives such as hydrated lime,cement or mixture of both to replace equal volume of mineral powder for alka-lization treatment on aggregate and rubber particles. In this article,the optimum anti- stripping agent is selected through laboratory tests,and its road use performance is verified.
