Steel slag anti-skid wearing layer asphalt mixture and preparation method thereof
The invention provides a steel slag anti-skid wearing layer asphalt mixture and a preparation method thereof, and the steel slag anti-skid wearing layer asphalt mixture comprises the following components in parts by mass: 10-50 parts of aggregate, 8-10 parts of mineral powder, 0.25-0.35 part of wood fiber, 1-3.5 parts of SBS modified asphalt and 40-80 parts of steel slag, the aggregate is limestone coarse aggregate with the particle size of 10-15 mm, limestone fine aggregate with the particle size of 5-10 mm and limestone fine aggregate with the particle size of 0-3 mm; the particle size of the mineral powder is 0-3mm. The aged steel slag is adopted to replace natural aggregate for construction of road engineering, so that the problem of shortage of stone is solved, the service quality of the pavement can be obviously improved, and the treatment cost of the steel slag is saved; according to the steel slag anti-skid wearing layer asphalt mixture, the steel slag mixing amount is 75%, the wearing layer is good in rut resistance and water damage resistance, and the volume stability and the low-temperature stability meet the standard requirements.
本发明提供一种钢渣抗滑磨耗层沥青混合料及其制备方法，按照质量分数，所述沥青混合料包括如下组分：集料10‑50份、矿粉8‑10份、木质纤维0.25‑0.35份、SBS改性沥青1‑3.5份和钢渣40‑80份；所述集料为粒径为10‑15mm、5‑10mm的石灰岩粗集料、0‑3mm的石灰岩细集料；所述矿粉的粒径为0‑3mm。采用陈化后钢渣替代天然集料进行道路工程的建设，解决了石料紧缺的问题，能明显改善路面的服务品质，节约了钢渣的处理成本；本发明中的钢渣抗滑磨耗层沥青混合料，钢渣掺量75％，磨耗层的抗车辙、抗水损害好，且体积稳定性、低温稳定性满足规范要求。
