Mineral fiber modified asphalt concrete and preparation method thereof
The invention belongs to the technical field of asphalt concrete, and relates to mineral fiber modified asphalt concrete and a preparation method thereof. The mineral fiber modified asphalt concrete comprises asphalt, aggregate, mineral powder and modified basalt fiber. The modified basalt fiber comprises 50-100 parts by weight of basalt fiber, 0.8-3 parts by weight of a silane coupling agent and 0.5-5 parts by weight of rubber, the silane coupling agent is located on the surface of the basalt fiber, and the rubber is located on the surface of the silane coupling agent. The modified basalt fiber is added into the asphalt concrete as a reinforcing material, and the excellent mechanical properties of high tensile strength and high elastic modulus are exerted, so that the comprehensive pavement performance of the asphalt concrete is improved; and the method is very beneficial to solving pavement diseases of special road sections, prolonging the service life and saving maintenance and repair funds.
本发明属于沥青混凝土技术领域，涉及一种矿物纤维改性沥青混凝土及其制备方法。所述矿物纤维改性沥青混凝土，包括沥青、集料、矿粉和改性玄武岩纤维。所述改性玄武岩纤维包括50～100份玄武岩纤维、0.8～3重量份硅烷偶联剂以及0.5～5重量份橡胶，硅烷偶联剂位于玄武岩纤维表面，橡胶位于硅烷偶联剂表面。本发明的改性玄武岩纤维作为增强材料加入沥青混凝土中，发挥其高抗拉强度、高弹性模量的优异力学特性，使沥青混凝土的综合路用性能得到改善；对于解决特殊路段的路面病害，延长使用寿命，节约养护与维修资金十分有益。
