摘要
为研究乳化型温拌剂对沥青性能指标的影响,选取二种温拌剂分别对SBS改性沥青和70号、90号基质沥青进行了三大指标试验、老化后性能试验以及黏度试验。试验结果表明:乳化型温拌剂对沥青针入度、软化点、延度和黏度影响较小,可有效改善沥青的老化。
For research the effect of emulsified warm mix agent on the performance index of asphalt , respectively two warm mix agents , SBS modified asphalt and 70 #, 90 # matrix asphalt were selected to do the three major indexes test , after aging performance test and viscosity test. The results showed that the emulsified warm mix agent had a smaller effect on asphalt penetration, softening point, ductility and viscosity influence, and could effectively improve the aging of asphalt.
