摘　　要：依托彩色自行车道铺装工程,对彩色沥青AC-13进行了配合比设计和路用性能试验,介绍其施工情况并进行现场检测。试验表明:设计的彩色沥青AC-13最佳油石比为5.0%、残留稳定度91.0%、冻融劈裂强度比89.2%、动稳定度2 132次/mm;施工完成的彩色沥青混凝土铺装层压实度98.0%、渗水系数88mL/min、构造深度0.77mm、平整度2.0mm。彩色沥青混凝土的路用性能高于行业规范对等级公路路面的指标要求,其施工工艺和设备与常规热拌沥青混合料相近,具有较高的推广应用价值。Relying on the engineering of color bike lanes paving, this article conducted the ration design and pavement performance of colored asphalt AC-13, and a brief description of construction information and on-site testing result were given. The result showed： the optimum aggregate ratio of colored asphalt AC-13 was 5.0%, the residual stability and freeze-thaw splitting strength ratio were 91.0% and 89.2%, the dynamic stability was 2132 times per ram; the degree of compaction of colored asphalt concrete pavement was 98.0%, permeability coefficient 88 ml/min, texture depth 0. 77 mm, flatness 2. 0 mm. The colored asphalt concrete pavement performance was above the industry norm for grade road surface target, and its construction technology and equipment were similar with conventional hot mix asphalt and had the high value of popularization.
