国产环氧沥青抗老化性能研究

随着我国交通事业的发展，对高性能材料如环氧沥青的需求将会越来越大．目前环氧沥青虽然仍主要依赖进口，但国产环氧沥青也已经研发并应用于工程实践。本文通过短期老化后环氧沥青的粘度试验和拉伸试验来评价国产环氧沥青的抗老化性能，通过马歇尔试验评价国产环氧沥青混合料的抗老化性能，并与美国环氧沥青的性能作对比。结果表明，国产环氧沥青的抗老化性能略逊于美国环氧沥青，但短期老化后仍满足技术指标要求．

Study on Anti-aging Performance of the Domestic Epoxy Asphalt

There is a larger and larger requirement of high performance materials such as epoxy asphalt with the development of the transportation in China. At present, epoxy asphalt mostly depends on importation, but the research, development and application of domestic one is still progressing. The article assessed the anti-aging performance of the domestic epoxy asphalt through viscosity test and tensile test after short-term aging, and the domestic epoxy asphalt mixture through Marshall test,by simultaneously comp...
