Asphalt concrete wearing layer doped with steel slag and preparation method of asphalt concrete wearing layer
The invention relates to the technical field of asphalt compositions, in particular to the field of IPCC08L95, and more particularly relates to a steel slag doped asphalt concrete wearing layer and a preparation method thereof. The steel slag asphalt concrete ultra-thin wearing layer comprises a steel slag asphalt concrete ultra-thin wearing layer and a modified asphalt concrete bonding layer from top to bottom. The thickness of the super-tough high-strength wearing layer is 1.8-3cm, so that the stability of the wearing layer can be improved, and the construction efficiency can be improved; when the weight ratio of the coarse aggregate to the fine aggregate is 1: (0.8-1.3), the drainage and noise reduction performance of the wearing layer can be improved; when the tensile strength of the epoxy modified asphalt concrete bonding layer is 2MPa and the elongation at break is greater than 100%, the crack resistance of the wearing layer can be improved; construction is simple and convenient, the structure of an old pavement does not need to be changed, and conventional construction equipment can be implemented.
本发明涉及沥青组合物技术领域，尤其涉及IPCC08L95领域，更具体的，涉及一种掺杂钢渣的沥青混凝土磨耗层及其制备方法。从上到下，包括钢渣沥青混凝土超薄磨耗层和改性沥青混凝土粘结层。所述超韧高强磨耗层的厚度为1.8‑3cm，可提高磨耗层稳定性同时提高施工效率；所述粗集料和细集料重量比为1：(0.8‑1.3)时，可提高磨耗层的排水以及降噪性能；所述环氧改性沥青混凝土粘结层的拉伸强度为2MPa，断裂伸长率大于100％时，可提高磨耗层抗裂性能；施工简便，无需改变旧路面的结构，常规施工设备即可以实施。
