Epoxy asphalt concrete for roads and bridges and preparation method thereof
The invention discloses epoxy asphalt concrete for roads and bridges and a preparation method of the epoxy asphalt concrete. The epoxy asphalt concrete is mainly prepared from the following raw materials in parts by weight: 35 to 45 parts of epoxy asphalt, 120 to 180 parts of cement, 250 to 350 parts of aggregate and 125 to 150 parts of water, wherein the epoxy asphalt is prepared from bio-based epoxy resin, matrix asphalt, modified sepiolite and a curing agent. According to the invention, petroleum-based epoxy resin is replaced with bio-based epoxy resin, so that dependence on petroleum resources is reduced, and the concept of green chemistry is met; sepiolite is comprehensively treated by ethylenediamine tetraacetic acid and epichlorohydrin, so that the use performance of the sepiolite as the epoxy asphalt filler can be fully exerted; according to the epoxy asphalt concrete prepared by the scheme, the cracking phenomenon of the concrete in a low-temperature environment in winter and the water absorption and hygroscopicity of pavements and bridge floors can be improved; and the epoxy asphalt concrete and the preparation method thereof provided by the invention can be widely applied to construction of roads and bridge surfaces.
本发明公开了一种道桥用环氧沥青混凝土及其制备方法。环氧沥青混凝土主要包括以下重量份原料，环氧沥青35‑45份、水泥120‑180份、集料250‑350份、水125‑150份。环氧沥青包括生物基环氧树脂、基质沥青、改性海泡石、固化剂组成；用生物基环氧树脂代替石油基环氧树脂，减少对石油资源的依赖，符合绿色化学的理念。海泡石通过乙二胺四乙酸、环氧氯丙烷的综合处理，可充分发挥海泡石作为环氧沥青填料的使用性能；通过本方案制备得到的环氧沥青混凝土可改善混凝土在冬季低温环境下的开裂现象和路面、桥面的吸水、吸湿性；本发明提供的环氧沥青混凝土及其制备方法可广泛用于道路、桥梁面的施工。
