摘要
通过比较欧洲、美国和中国交通部现行规范中的改性沥青储存稳定性试验方法,分析了不同方法的异同点。结合当前我国离析实践中存在的主要问题,重点研究了不同冷却温度对于离析试验结果的影响,提出了离析试验方法的改进和完善建议。
By comparing modified asphalt storage stability test methods from the specification of Europe,United States and China,analyzes the similarities and differences of different methods.Combining the main problems existing in the practice in our country,segregation,this paper mainly study the effects of different cooling temperature on segregation test results,puts forward the segregation test methods for improvement and perfect suggestions.
