Warm-mixing flame-retardant SMA asphalt mixture as well as preparation method, application and construction method thereof
The invention relates to the technical field of asphalt road construction, and particularly discloses a warm-mixing flame-retardant SMA asphalt mixture as well as a preparation method, application and a construction method thereof. The warm-mixing flame-retardant SMA asphalt mixture comprises SBS modified asphalt, aggregate, fibers, a Sasobit warm-mixing agent and a flame retardant. The preparation method comprises the steps: S1, heating and drying a coarse aggregate, a fine aggregate and SBS modified asphalt; S2, adding the SBS asphalt mixture into a stirring pot, and uniformly stirring; and S3, putting the mixture obtained in the step S2 into a drying oven for molding. The construction method of the warm-mixing flame-retardant SMA asphalt mixture comprises the steps of paving, initial pressing, re-pressing, final pressing and the like. The warm-mixing flame-retardant SMA asphalt mixture can be used for paving tunnels and pavements, has excellent high-temperature rut resistance, low-temperature crack resistance and water stability, and has better pavement performance than a hot-mixed mixture; and in addition, the warm-mixing flame-retardant SMA mixture in the preparation method and the construction method can reduce the mixing, paving and compacting temperature by about 20 DEG C.
本申请涉及沥青道路建设技术领域，具体公开了一种温拌阻燃SMA沥青混合料及其制备方法及用途及施工方法。一种温拌阻燃SMA沥青混合料包括SBS改性沥青、集料、纤维、Sasobit温拌剂和阻燃剂；其制备方法为：S1，将粗集料、细集料和SBS改性沥青加热并烘干；S2，将SBS沥青混合料加入拌锅搅拌均匀；S3，将S2中的混合料放入烘箱中成型。本申请的温拌阻燃SMA沥青混合料的施工方法包括摊铺、初压、复压以及终压等步骤。本申请的温拌阻燃SMA沥青混合料可用于隧道和路面铺装，其具有优良的高温抗车辙性能、低温抗裂性能和水稳定性，路用性能优于热拌混合料；另外，本申请的制备方法和施工方法中温拌阻燃SMA混合料可降低拌和、摊铺、压实温度20℃左右。
