摘　　要：结合非机动车道彩色沥青路面实体工程,根据集料筛分结果和原材料的性质,确定开级配沥青混合料上面层目标配合比,测试其技术指标和动稳定度指标。结果表明:开级配沥青混合料的最佳油石比为5.0%,密度指标、空隙率、稳定度指标满足规范要求,动稳定度均值为3496次/mm,大于规范值,满足要求。The target mix ratio and optimum asphalt - aggregate ratio of open gradation asphalt mixture were determined according to the screening resuhs of aggregates and raw material properties combining with the non - motorized vehicles road of color asphalt pavement entity index were tested. The results show that the optimum engineering. Its technical indexes and dynamic stability asphalt - aggregate ratio of this asphalt mixture was 5.0%. Its density index, porosity and stability index meet the standard requirements, and the mean dynamic stability is 3496 times/mm, which is greater than the standard value and meets the requirements.
