Steel slag anti-skid pavement surface layer for alpine region and construction method of steel slag anti-skid pavement surface layer
The invention discloses a steel slag antiskid pavement surface layer for an alpine region and a construction method of the steel slag antiskid pavement surface layer, and belongs to the field of road engineering. The pavement surface layer is formed by sequentially laying an embedded layer and a wearing layer, wherein the embedded layer comprises the following raw materials in parts by weight: 20-35 parts of steel slag, 45-65 parts of limestone, 10-11 parts of mineral powder and 6.5-7.0 parts of asphalt; the wearing layer comprises the following raw materials in parts by weight: 95-98 parts of steel slag, 0-3 parts of mineral powder and 1-3 parts of asphalt, the wearing layer is spread on the surface of the embedded layer after the embedded layer is paved, and the wearing layer is pressed into the embedded layer through low-speed rolling of a steel wheel road roller. The characteristics of large density, high strength, abrasion resistance, crushing resistance, good particle shape and the like of the steel slag are utilized, and the steel slag has good adhesive force with asphalt, is applied to special process pavements, has excellent skid resistance, water damage resistance, freeze-thaw resistance and durability, improves the driving safety, improves the utilization rate of the steel slag, and is low in cost, energy-saving and environment-friendly.
本发明公开了一种用于高寒地区的钢渣抗滑路面表层及其施工方法，属于道路工程领域。该路面表层由嵌入层和磨耗层依次铺设而成，嵌入层包括如下按重量份计的原料：钢渣20‑35份、石灰岩45‑65份、矿粉10‑11份、沥青6.5‑7.0份；磨耗层包括如下按重量份计的原料：钢渣95‑98份、矿粉0‑3份、沥青1‑3份，磨耗层在嵌入层摊铺完成后撒布于嵌入层表面，并由钢轮压路机低速碾压，将其压入嵌入层中。本发明利用钢渣密度大、强度高、抗磨耗和抗破碎，良好颗粒形状等特性，以及其与沥青良好粘附力，应用于特殊工艺路面，具有优异的抗滑性、抗水损害性、抗冻融性和耐久性，提高行车安全，且提升钢渣利用率，成本低，节能环保。
