High-strength pavement material and preparation method thereof
The invention relates to the technical field of pavement materials, and discloses a high-strength pavement material and a preparation method thereof.The high-strength pavement material is prepared from, by weight, 20-35 parts of nylon fiber, 80-100 parts of water, 50-80 parts of cement, 55-75 parts of emulsified asphalt, 55-75 parts of modified asphalt, 15-25 parts of expanded perlite, 5-15 parts of coal ash, 10-20 parts of rubber modifier, 5-10 parts of enhancer and 10-15 parts of curing agent. The emulsified asphalt is prepared by dispersing road asphalt which is usually used at high temperature into water through mechanical stirring and chemical stabilization methods and liquefying the road asphalt into a road building material which is very low in viscosity and strong in fluidity at normal temperature. The performance of the pavement material can be improved through the matching effect of the emulsified asphalt and the modified asphalt, and the strength of the pavement is improved.
本发明涉及路面材料技术领域，且公开了一种高强度路面材料及其制备方法，按重量份由以下组分组成：尼龙纤维：20‑35份，水：80‑100份，水泥50‑80份，乳化沥青：55‑75份，改性沥青：55‑75份，膨胀珍珠岩：15‑25份，煤灰：5‑15份，橡胶类改性剂：10‑20份，增强剂：5‑10份，固化剂：10‑15份，光稳定剂：8‑17份，混合集料：30‑45份，所用的乳化沥青是将通常高温使用的道路沥青，经过机械搅拌和化学稳定的方法，扩散到水中而液化成常温下粘度很低、流动性强的一种道路建筑材料。本发明通过乳化沥青与改性沥青的配合作用可以改善路面材料的性能，提高路面自身的强度。
