Anti-rutting asphalt and preparation method thereof
The invention relates to the technical field of road engineering materials, and particularly discloses anti-rutting asphalt and a preparation method thereof. The anti-rutting asphalt comprises an asphalt mixture and cement slurry in a weight ratio of (3-4.8): 1; based on the total amount of the asphalt mixture, the asphalt mixture is prepared from the following raw materials in parts by weight: 3-10 parts of matrix asphalt, 80-100 parts of coarse aggregate, 10-20 parts of fine aggregate and 0.05-0.3 part of an anti-rut agent, based on the total amount of the cement slurry, the cement slurry is prepared from the following raw materials in parts by weight: 0-70 parts of cement, 80-100 parts of water, 20-40 parts of mineral powder, 40-80 parts of sand and 2-6 parts of an additive, the preparation method comprises the following steps: firstly preparing the asphalt mixture, then flattening, pouring the cement slurry on the flattened asphalt mixture, and curing to obtain the asphalt pavement. The asphalt provided by the invention has excellent anti-rutting performance.
本申请涉及道路工程材料技术领域，具体公开了一种抗车辙沥青及其制备方法。抗车辙沥青包括重量比为（3‑4.8）:1的沥青混合料和水泥浆料；以沥青混合料总量计，沥青混合料由包含以下重量份的原料制成：基质沥青3‑10份、粗集料80‑100份、细集料10‑20份和抗车辙剂0.05‑0.3份；以水泥浆料总量计，水泥浆料由包含以下重量份的原料制成：水泥0‑70份、水80‑100份、矿粉20‑40份、砂40‑80份和外加剂2‑6份；其制备方法为：先制备沥青混合料，然后摊平，再将水泥浆料灌注在摊平的沥青混合料上，养护，即可制得沥青路面。本申请的沥青具有优异的抗车辙性能。
