聚合物复合改性沥青及其胶浆流变性能
|
摘要
采用动态剪切的流变试验、弯曲梁的流变试验和测力延度试验等流变力学实验方法,对未老化复合改性沥青及其胶浆性能开展试验研究。结果表明复合改性沥青的高温流变力学性能优于常规SBS改性沥青。兼顾高、低温性质的复合改性沥青胶浆适宜的粉胶比为1.4,粉胶比上限范围为1.6。
In order to evaluate the mechanical characteristics of the composite modified asphalt in the non-static loads, several rheological mechanical experiments were carried out which include dynamic shear rheometer test, bending beam rheological test and the force ductility test to study the same composite modified asphalt and mucilage performance. The results show that the rheological properties of the composite at high temperature is superior to conventional SBS modified asphalt, meanwhile, the suitable range of the composite powder modified asphalt mineral powder adhesive cement ratio can be achieved by the rheological mechanical experiments. The conclusion is the range of mineral powder adhesive cement maximum ratio suitable to both high and low temperature properties is 1.6, and the proper one is 1.4.
