Asphalt mixture modified by waste basalt fiber reinforced composite material
The invention relates to an asphalt mixture modified by a waste basalt fiber reinforced composite material. The asphalt mixture is prepared from the following components in parts by weight: 4-6 parts of asphalt, 0.2-0.4 part of the waste basalt fiber reinforced composite material and 93-95 parts of mineral aggregate, the mineral aggregate is composed of gravel with the particle size ranging from 19 mm to 26.5 mm, gravel with the particle size ranging from 9.5 mm to 19 mm, gravel with the particle size ranging from 4.75 mm to 9.5 mm, gravel with the particle size ranging from 2.36 mm to 4.75 mm, machine-made sand and mineral powder. According to the invention, the waste basalt fiber reinforced composite material is recycled, and the resin on the surface of the basalt fiber reinforced composite material and the asphalt have good compatibility and reinforcing and toughening effects are achieved between the fiber and the asphalt, so the anti-rutting performance, low-temperature crack resistance and other pavement performances of the asphalt mixture are greatly improved.
本发明涉及一种利用废弃玄武岩纤维增强复合材料改性的沥青混合料，包括如下组分：4‑6份沥青，0.2‑0.4份废弃的玄武岩纤维增强复合材料，93‑95份矿料；矿料由粒径为19‑26.5mm的碎石、粒径为9.5‑19mm的碎石、粒径为4.75‑9.5mm的碎石、粒径为2.36‑4.75mm的碎石、机制砂和矿粉组成；本发明对废弃的玄武岩纤维增强复合材料进行回收利用，因玄武岩纤维增强复合材料表面的树脂与沥青之间具有良好的相容性，在纤维与沥青之间起到增强、增韧的效果，所以对于沥青混合料的抗车辙性能、低温抗裂等路用性能有大幅提高。
