高性能沥青混合料路用性能的研究

Study on superpave bituminous mixture performance

通过试验研究,系统分析了高性能沥青混合料和密级配沥青砼的路用性能,包括马歇尔稳定度,水稳定性,抗冻融破坏性,低温抗裂性,高温稳定性,疲劳耐久性、摩擦系数和构造深度.结果表明:高性能沥青混合料具有较密级配沥青混合料更好的路用性能,可以改善沥青路面使用品质,延长使用寿命,具有较好的经济和社会效益,是一种性能优良的沥青混合料.

A series of test are carried out to analyze the characteristics of Marshall stability,high temperature rutting,low temperature crack resistance,water stability,freeze and cleave strength ratio,texture meter,fatigue resistance and skid resistance of bituminous mixtures and denseior to the others.Finally the results show that its life has been prolonged,of better social and economic value,and it is a kind of higherperformance bituminous mixture.
