本文采用锁轮式测定车对美国印第安纳州六条Superpave-5路面通车1年后的抗滑系数进行测试,结合室内试验分析了矿料性质、混合料体积指标和级配对Superpave-5路面抗滑性能的影响,建立了各影响因素与Superpave-5路面抗滑系数之间的关系,提出了影响Superpave-5路面抗滑性能的关键指标、筛孔及推荐级配走向。结果表明:空隙率和沥青饱和度是影响Superpave-5路面抗滑性能的关键指标,与路面抗滑系数之间的斯皮尔曼等级相关系数分别为0.8281和-0.6571;1.18mm筛孔通过率与Superpave-5路面抗滑系数间的灰熵关联度最大(达到0.9914),是影响其抗滑性能的关键筛孔;优化Superpave-5主骨架级配和调整第一控制筛孔...

In order to research influence factors on friction performance of 4.75 mm NMAS Superior Performing Asphalt Pavement（Superpave-5）,locked wheel trailer was chosen to test the friction numbers of the 6 test roads in Indiana after one year open to traffic.Combined with laboratory tests,influences of properties of aggregates,volumetric indexes and gradations on friction performance of Superpave-5 were analyzed.Then relationship between the influence factors and friction numbers was established.Further,key indicators,sieve size and gradation trend ...
