粗骨架结构沥青混合料路用性能

通过试验研究．系统分析了粗骨架结构沥青混合料和密级配沥青混凝土的路用性能，包括马歇尔稳定度、水稳定性、低温抗裂性、高温稳定度、疲劳耐久性和抗滑性能．并对集料级配骨架形成与空隙率的关系做了分析。结果表明，粗骨架结构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，是一种优良的路面材料。

Road Performance of Bituminous Mixtures with Thick Skeleton Texture

By a series of tests,the characteristics of Marshall stability,high temperature rutting,low temperature crack resistance,water stability,fatigue resistance and skid resistance of bituminous mixtures with thick skeleton texture and dense graded bitumen concrete are analyzed. At the same time, the relation between skeleton forming of mixtures and percentage of voids is analyzed too. The results show that the road performance of bituminous mixtures with thickness skeleton texture is better than others and it can lengthen the life span of bituminous pavement.
