摘要
以橡胶沥青为研究对象,采用动态剪切流变仪,获取橡胶沥青的流变参数,建立复数模量主曲线,针对胶粉细度和沥青标号对其性能的影响进行分析,通过开展应力重复蠕变恢复试验,对橡胶沥青的高温性能进行研究。
Taking the rubber asphalt as the research object,the dynamic shear rheometer is used to obtain the rheological parameters of rubber asphalt,establish the master curve of modulus of complex number,and analyze the influence of rubber powder fineness and asphalt grade on its properties.The high-temperature property of rubber asphalt is studied through the repeated stress creep recovery test.
