摘　　要：通过对比分别掺入3种温拌剂后的橡胶沥青混凝土在不同成型方法和不同成型温度下所呈现的压实度、空隙率的差异,得出温拌橡胶沥青混凝土压实性能排序;采用荧光显微镜观察温拌橡胶沥青微观结构,对比分析得出Evotherm3G型温拌橡胶沥青中胶粉溶胀发育程度最高,且技术性能相对更为优越,可为温拌橡胶沥青混凝土施工提供技术参考。The compaction characteristics of rubberized asphalt concrete mixed with three types of warm mix agents were sorted by comparing the differences of compaction degree and porosity under different forming methods and temperatures. Fluorescence microscope was applied to observe the microstructure of warm mix rubberized asphalt, and Evotherm 3G was found to be the highest in development degree of rubber powder swelling. The research provides technical reference for construction of warm mix asphalt concrete.
