摘　　要：依托上海G15嘉浏段拓宽改建工程,研究木质素纤维、聚酯纤维、玄武岩纤维和高强添加剂等对SMA-13沥青混合料路用性能的影响。基于G15嘉浏段现场条件及未来使用需求,采用确定适用于G15嘉浏段高速公路沥青面层的纤维和外掺剂类型。采用室内试验对沥青混合料的路用性能进行分析,结果表明:掺入木质素纤维的SMA-13的沥青混合料的路用性能较好,可有效满足G15嘉浏段高速公路运营使用需求。最后对拌和厂实际生产的沥青混合料的性能进行评价。Relying on Shanghai G15 Jialiu Section Widening Reconstruction Project,the influence of lignin fiber,polyester fiber,basalt fiber and high-strength additives on the road performance of SMA-13 asphalt mixture is studied.Based on the site conditions of G15 Jialiu Section and its future use requirements,the types of fibers and admixtures suitable for the asphalt surface of G15 Jialiu Section are adopted.The laboratory test is used to analyze the pavement performance of the asphalt mixture.The results show that the pavement performance of the SMA-13 asphalt mixture mixed with the lignin fiber is better,and can effectively meet the operating demands of the G15 Jialiu Section of the expressway.Finally,the performance of the asphalt mixture actually produced by the mixing plant is evaluated.
