大空隙排水沥青混合料试验研究

Asphalt Mixture Test of Big Gap Drainage

采用大空隙排水沥青混合料改善目前沥青路面面层性能,分别就混合料的组成成分和外加剂用量进行室内试验,确定混合料集配、沥青最佳用量和外加剂用量。通过试验验证了其优良的排水性能,对大空隙排水沥青混合料的现实应用具有指导意义。

In this paper, we use big gap drainage asphalt mixture to improve asphalt pavement per-formance. To ensure the distribution of test, the optimum dose of asphalt and the dose of admix-ture, we make a indoor test. Meanwhile, we verified that this mixture has excellent drainage per-formance, which will play a guiding role in the practical application of the big gap drainage as-phalt mixture.
