Composite high-modulus agent for anti-rutting asphalt pavement and preparation method of composite high-modulus agent
The invention belongs to the field of road engineering materials, and relates to a high-modulus agent, in particular to a composite high-modulus agent for an anti-rutting asphalt pavement and a preparation method of the composite high-modulus agent. The composite high-modulus agent comprises the following raw materials in parts by mass: 50%-70% of old asphalt pavement milling material recycled powder, 5%-15% of composite high-modulus modified asphalt, 3%-10% of polyethylene wax, 2%-5% of solvent oil, 5%-8% of fibers, 0.1%-0.5% of an asphalt deodorant and 10%-15% of high molecular weight polyethylene, wherein the total mass of the raw materials is 100%. The composite high-modulus agent does not reduce the low-temperature crack resistance and water damage resistance of an asphalt mixture on the premise of improving the modulus of an asphalt pavement and improving the rutting resistance, and meanwhile, has the characteristics of low cost, environment friendliness, convenience in use, convenience in popularization and application and the like.
本发明属于道路工程材料领域，涉及一种高模量剂，尤其涉及一种抗车辙沥青路面的复合高模量剂及其制备方法。该复合高模量剂包含以下按质量份计的原材料：旧沥青路面铣刨料回收粉50％‑70％，复合高模量改性沥青5％‑15％，聚乙烯蜡3％‑10％，溶剂油2％‑5％，纤维5％‑8％，沥青净味剂0.1％‑0.5％，高分子量聚乙烯10％‑15％，其总质量满足100％。该复合高模量剂在提高沥青路面模量，增加抗车辙性能的前提下，又不降低沥青混合料的低温抗裂性能及抗水损害能力，同时，兼顾成本低廉，绿色环保，使用方便，便于推广应用等特点。
