为研究温拌SBS改性沥青混合料的降温效果,采用Superpave提出的旋转压实仪(SGC)成型试件,根据温拌SBS改性沥青混合料的压实特性和体积特性分析了添加温拌剂后SBS沥青混合料的降温效果,确定了温拌SBS改性沥青混合料合适的压实温度;通过车辙试验、冻融劈裂试验、低温弯曲试验研究了温拌SBS改性沥青混合料的主要试验性能,试验结果表明温拌SBS改性沥青混合料具有良好的路用性能,均符合现行规范要求。
In order to study the cooling effect of warm-mix SBS modified asphalt mixture, the rotary compaction instrument (SGC) prototype proposed by Superpave was used. According to the compaction and volume characteristics of warm-mix SBS modified asphalt mixture, After the agent SBS asphalt mixture cooling effect, to determine the warm mixing SBS modified asphalt mixture suitable compaction temperature; through rutting test, freeze-thaw splitting test, low temperature bending test of warm mix SBS modified asphalt mixture The main test performance, the test results show that warm mix SBS modified asphalt mixture has good road performance, are in line with current norms and requirements.
