Expressway trench cover plate and preparation method and application thereof
The invention belongs to the technical field of engineering materials, and particularly relates to an expressway trench cover plate and a preparation method and application thereof. The preparation method comprises the following steps: S1, preparing raw materials; s2, crushing peach gum, sieving the crushed peach gum with a 80-100-mesh sieve, adding the sieved peach gum into the matrix asphalt, and adding nano-silica, polyvinyl acetate and water at the same time to obtain a mixed system; s3, stirring the mixed system for 30-45 minutes at a high speed under the condition of 110-115 DEG C to obtain modified asphalt; s4, mixing the cement, the silica fume, the river sand, the granite, the basalt fiber and the carboxylic acid water reducing agent, and adding the modified asphalt while stirring until the materials are uniformly mixed, so as to obtain concrete slurry; and S5, pouring the concrete slurry into a trench cover plate mold, uniformly vibrating, and carrying out the steps of curing and demolding to obtain the highway trench cover plate. The modified asphalt is added into the concrete, so that the toughness and the mechanical property of the cover plate are improved at the same time.
本发明属于工程材料技术领域，具体涉及一种高速公路沟盖板及其制备方法、应用。制备方法包括：S1.原料准备；S2.将桃胶粉碎后过80‑100目筛，加入基质沥青中，同时加入纳米二氧化硅、聚醋酸乙烯酯和水，得到混合体系；S3.将所述混合体系在110‑115℃条件下高速搅拌30‑45min，得到改性沥青；S4.将所述水泥、硅灰、河砂、米石、玄武岩纤维和羧酸减水剂混合，边搅拌边加入所述改性沥青，直至混合均匀，得到混凝土浆液；S5.将所述混凝土浆液浇筑于沟盖板模具中，振捣均匀，并进行养护、脱模步骤，得到所述高速公路沟盖板。本发明将改性后的沥青加入混凝土中，实现了盖板韧性和力学性能的同时提升。
