摘要
为研究不同温拌添加剂对沥青混合料低温性能的影响,选取抗低温性能较好的SBS沥青,并采用同一配合比,分别加入Sasobit、Evotherm和陆路邦3种不同的温拌添加剂,通过小梁弯曲试验进行低温性能的比较和分析。试验结果表明,不同类型的温拌添加剂对沥青混合料的应力和应变有不同的影响。
In order to study the influence of different warm mix additives on the low temperature performance of asphalt mixture,the SBS asphalt with the better low temperature performance is selected and the same mixture ratio is also used with the three different warm mix additives such as Sasobit,Evotherm and Lulubang. The low temperature performance is compared and analyzed by the trabecular bending test method. The testing result shows that the different warm mix additives have different influences on the stress and strain of the asphalt mixture.
