| 摘 要： | 通过室内试验研究了改性剂、石料级配和沥青标号对沥青混合料低温抗裂性能的影响,试验结果表明:SBS改性剂对沥青混合料的低温抗裂性能提高不显著,大粒径石料可以提高混合料低温弯拉强度,高标号沥青可以提高混合料的低温弯拉应变。

| Abstract: | In the paper,the factors in affecting the crack resistance of asphalt in low temperature is researched by the experiments,the factors include asphalt modifier, aggregate and asphalt character.By the experiment data,these results show that,the crack resistance of mixture in low temperature can not be improved much using SBS modifier,the flexural tensile strength of mixture is improved by adopting larger diameter aggregate,the flexural tensile strain is also improved by using the asphalt with high strength code. |
