摘要
从胶粉活化机理、胶粉活化改性方法、胶粉活化对改性沥青性能影响3个方面,对目前活化胶粉的研究进展进行了分类总结。研究发现,活化胶粉改性沥青的低温性能、储存稳定性、感温性能等比未处理胶粉改性沥青更优。该研究成果可为后续活化胶粉改性沥青的研究和应用提供参考。
From effect of rubber powder activation mechanism,rubber powder activation modification method and rubber powder activation on the performance of modified asphalt,the current research progress of activated rubber powder is classified and summarized.It is found that the low temperature performance,storage stability and temperature sensitivity of activated rubber powder modified asphalt are better than that of untreated rubber powder modified asphalt.The research results can provide a reference for the subsequent research and application of activated rubber powder modified asphalt.
