High-temperature-resistant anti-rutting asphalt pavement and construction method thereof
The invention relates to the technical field of traffic engineering, and particularly discloses a high-temperature-resistant anti-rutting asphalt pavement and a construction method thereof. The high-temperature-resistant anti-rutting asphalt pavement is formed by paving an asphalt mixture, the asphalt mixture comprises the following components in parts by weight: 160-180 parts of matrix asphalt, 1280-1340 parts of modified aggregate and 100-120 parts of filler, the modified aggregate is granite macadam coated with a cement stone shell layer on the surface, and the cement stone shell layer is a hardened product of cement paste. In the asphalt pavement paved by using the asphalt mixture disclosed by the invention, the asphalt has a good adhesion effect on the modified aggregate, so that the high-temperature deformation resistance is improved, and the anti-rutting effect of the asphalt pavement is favorably improved.
本申请涉及交通工程技术领域,具体公开了一种耐高温抗车辙沥青路面及其施工方法。耐高温抗车辙沥青路面由沥青混合料铺筑而成,沥青混合料包括如下重量份的组分:基质沥青160‑180份,改性骨料1280‑1340份,填料100‑120份,改性骨料为表面包覆有水泥石壳层的花岗岩碎石,水泥石壳层为水泥浆的硬化产物。在使用本申请的沥青混合料铺筑的沥青路面中,沥青对改性骨料具有良好的粘附效果,因此高温抗变形能力得到了提升,有助于改善沥青路面的抗车辙效果。
