摘要
分析了制备工艺、胶粉粒径以及外加添加剂对胶粉改性沥青常规使用性能和稳定性的影响。结果表明:在一定的范围内,胶粉粒径细,对沥青性能的改善较好;加入相容剂可改变沥青胶体体系的溶剂化层的结构和性质;交联剂的加入,增大了体系的稳定性。
Influence of crumb rubber of different size, process and other additive on the properties of crumb rubber modified asphalt were investigated. The size of rubber is smaller that rubber modified asphalt performance is better in the reasonable range. The framework and performance of asphalt was changed and the stability of modified asphalt was meliorate when the additive had been added. It was shown that the stability of rubber modified asphalt is improved significantly through the test of modified asphalt.
