Ultrathin wearing layer based on basalt fine aggregate and high-toughness asphalt and preparation method thereof
The invention relates to the technical field of road engineering materials, in particular to an ultra-thin wearing layer based on basalt fine aggregate and high-toughness asphalt and a preparation method of the ultra-thin wearing layer. The ultra-thin wearing layer is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 5.5 to 6.5 parts of high-toughness asphalt and 0.3 to 0.6 part of cellulose; the high-toughness asphalt comprises the following raw materials: matrix asphalt, SBS, rubber powder, natural asphalt and a solubilizer, the cellulose comprises sepiolite fiber, polypropylene fiber and basalt fiber. The mineral aggregate adopted by the invention contains the basalt fine aggregate, so that the utilization rate of basalt resources can be increased, and the production cost is effectively reduced; the mixture of the sepiolite fiber, the polypropylene fiber and the basalt fiber is used as the stabilizer, and the natural asphalt is used for modifying the matrix asphalt, so that the composite asphalt has high toughness, and the prepared ultra-thin wearing layer is small in thickness and has excellent durability, stability and skid resistance.
本发明涉及道路工程材料技术领域，特别是涉及基于玄武岩细集料和高韧沥青的极薄磨耗层及其制备方法。所述极薄磨耗层包括如下原料：100份矿料、5.5～6.5份高韧沥青、0.3～0.6份纤维素；高韧沥青的原料包括基质沥青、SBS、橡胶粉、天然沥青和增溶剂；纤维素包括海泡石纤维、聚丙烯纤维和玄武岩纤维。本发明采用的矿料中包含玄武岩细集料，能够提高玄武岩资源的利用率，有效降低生产成本；本发明以海泡石纤维、聚丙烯纤维和玄武岩纤维的混合物作为稳定剂，利用天然沥青对基质沥青进行改性，能够使得复合沥青具备高韧的性能，制备得到的极薄磨耗层厚度很小且具备优异的耐久性、稳定性和抗滑性能。
