摘要
通过对橡胶颗粒沥青混合料进行低温弯曲试验,并运用统计学检验和灰熵法对试验结果进行分析。结果表明:对于不同掺量橡胶颗粒的沥青混合料,掺加3%橡胶颗粒能显著提高沥青混合料的低温性能,其灰熵关联度顺序为:沥青用量>流值>毛体积密度>空隙率。
The low temperature bending test is used and analysed the rubber particles and asphalt mixture by using the method of statistical tests and grey entropy.The results show that different content have different results,adding 3% granulated crumb rubber is the best.The grey entropy’s order is： saturation asphalt consumption Marshall stability bulk volume density flow value clearance percentage prosity.
