Asphalt mixture based on water-damage-resistant modified steel slag and preparation method thereof
The invention relates to an asphalt mixture based on water-damage-resistant modified steel slag and a preparation method thereof. The asphalt mixture based on the water-damage-resistant modified steel slag is prepared from 63 to 73 parts of basalt coarse aggregate, 30 to 35 parts of steel slag coarse aggregate, 1 to 2 parts of mineral powder filler, 5 to 6 parts of SBS (Styrene Butadiene Styrene) modified asphalt, 0.3 to 0.6 part of fiber and 5 to 10 parts of steel slag surface modifier. Compared with the prior art, the existing stock of the steel slag can be effectively utilized, and the problems of environmental pollution and stone shortage are solved; due to the angularity and void ratio of the steel slag, the friction and embedding and extruding effects of the mixture are enhanced, and the adhesion of the asphalt and the steel slag is greatly improved, so that the service life of the pavement is effectively prolonged, and the skid resistance of the pavement is effectively improved; the steel slag is subjected to surface modification by using the steel slag surface modifier, so that the steel slag and the steel slag are subjected to hydrolysis and curing reaction, the bonding capacity between the asphalt and the coarse aggregate can be effectively improved, the surface friction coefficient of the steel slag is increased, and the water damage resistance and the water stability of the mixture are remarkably enhanced.
本发明涉及一种基于耐水损性改性钢渣的沥青混合料及其制备方法，其中基于耐水损性改性钢渣的沥青混合料包括：玄武岩粗集料63‑73份，钢渣粗集料30‑35份，矿粉填料1‑2份，SBS改性沥青5‑6份，纤维0.3‑0.6份，钢渣表面改性剂5‑10份。与现有技术相比，本发明可以有效利用钢渣的现有存量，也解决了环境污染和石料短缺的问题；由于钢渣本身的棱角性和空隙率增强了混合料的摩擦与嵌挤作用，大大提高了沥青与钢渣的粘附性，从而有效提高了路面的使用寿命及抗滑性；使用钢渣表面改性剂对钢渣进行表面改性，使其与钢渣发生水解和固化反应，可有效改善沥青与粗集料之间的粘接能力，增大钢渣表面摩擦系数，显著增强了混合料的抗水损性和水稳定性。
