为了评价温拌剂对橡胶沥青的降温效果及其对橡胶沥青混合料路用性能的影响,对掺加Sasobit后的橡胶沥青胶结料进行性能测试,结合橡胶沥青混合料正常温度拌和成型的试件,与分别添加Sasobit后降低拌和成型温度制作的橡胶沥青混合料试件进行测试分析,结果表明,Sasobit使橡胶沥青胶结料的高温稳定性得到提高,Sasobit可以使橡胶沥青混合料在较低的拌和成型温度制作试件,孔隙率不变,低温抗裂性、高温稳定性及水稳定性得到提高。因此,通过添加Sasobit降低橡胶沥青混合料的拌和及成型温度是可行的。
In order to evaluate the effect of warm mix on the cooling effect of rubber asphalt and its influence on the road performance of rubber asphalt mixture, the performance of rubber asphalt binder after mixing with Sasobit was tested, and the specimens mixed with asphalt mixture at normal temperature , Respectively, with the addition of Sasobit to reduce the molding temperature of rubber asphalt mixture samples were tested and analyzed, the results show that the Sasobit rubber asphalt binder high temperature stability is improved, Sasobit rubber asphalt mixture can be made in the lower mixing Molding temperature of the specimen, the same porosity, low temperature crack resistance, high temperature stability and water stability is improved. Therefore, it is feasible to reduce the mixing and forming temperature of rubber asphalt by adding Sasobit.
