High-strength anti-rutting asphalt concrete and preparation method thereof
The invention discloses high-strength anti-rut asphalt concrete and a preparation method thereof. The high-strength anti-rut asphalt concrete is prepared from the following raw materials in parts by weight: 6-10 parts of cement, 65-85 parts of coarse aggregate, 19-23 parts of fine aggregate, 18-27 parts of modified asphalt, 2-5 parts of fibers, 0.4-0.7 part of an anti-rut agent, 3-4 parts of epoxy resin and 3-4 parts of a curing agent. The preparation method comprises the following steps: preparing the rice husk charcoal; preparing modified asphalt; uniformly mixing the dried and crushed coarse aggregate with cement and fine aggregate to obtain a mixture A; heating the modified asphalt, then adding epoxy resin, a curing agent and fibers, stirring for a period of time, adding the mixture A, and uniformly mixing to obtain a mixture B; rolling the mixture B until the surface is smooth, and cooling; the asphalt concrete prepared by the invention can bear the operation of vehicles with large load and high tire pressure and can bear larger shear stress, the deformation resistance is also greatly improved, and the water stability is stronger.
本发明公开了一种高强抗车辙沥青混凝土及其制备方法，其由以下重量份的原料制成：6‑10份水泥、65‑85份粗集料、19‑23份细集料、18‑27份改性沥青、2‑5份纤维、0.4‑0.7份抗车辙剂、3‑4份环氧树脂、3‑4份固化剂；其制备方法包括：稻壳炭的制备；改性沥青的制备；将烘干、粉碎的粗集料与水泥、细集料混合均匀，得到混合料A；将所述改性沥青进行加热，随后加入环氧树脂、固化剂和纤维，搅拌一段时间后，加入所述混合料A混合均匀，得到混合料B；将所述混合料B碾压至表面平滑、冷却；本发明制备的沥青混凝土能够承受载重大、胎压高的车辆的运行，承受较大的剪切应力，抗形变能力也大大提升，水稳定性较强。
