Road SGF ultra-thin anti-skid layer and preparation method thereof
The invention discloses a road SGF ultra-thin anti-skid layer and a preparation method thereof, and relates to the technical field of road construction. Specifically, the preparation method of the road SGF ultra-thin anti-skid layer comprises the steps that first high-viscosity modified emulsified asphalt is sprayed on the surface of a road, and the spraying amount is 1-1.2 L/m < 2 >; spreading a steel slag rubber powder mixture and glass fibers before demulsification of the first high-viscosity modified emulsified asphalt to obtain a first middle layer; wherein the steel slag and rubber powder mixture is a mixture of single-grade steel slag and rubber powder; the total spreading amount of the steel slag and rubber powder mixture and the glass fibers is 10-12 kg/m < 2 >, the weight ratio of the steel slag to the rubber powder is 100: 1-100: 3, and the weight ratio of the steel slag and rubber powder mixture to the glass fibers is 100: 0.2-100: 1; after the first high-viscosity modified emulsified asphalt is demulsified, rolling and kneading by adopting a rubber wheel road roller to obtain a second middle layer; spraying second high-viscosity modified emulsified asphalt on the surface of the second middle layer, wherein the spraying amount is 0.3-0.5 L/m < 2 >; and after the second high-viscosity modified emulsified asphalt is demulsified, standing for 1-2 hours to obtain the road SGF ultra-thin anti-skid layer. The preparation method disclosed by the invention is simple and has low requirements on construction conditions, and the obtained SGF ultra-thin anti-skid layer has the advantages of small layer thickness, high anti-skid coefficient, stable performance and good economic performance.
本发明公开了一种道路SGF极薄抗滑层及其制备方法，涉及道路施工技术领域。具体的，道路SGF极薄抗滑层的制备方法包括：在道路表面喷洒第一高粘改性乳化沥青，喷洒量为1～1.2L/m2；在第一高粘改性乳化沥青破乳前撒布钢渣胶粉混合物、玻璃纤维，得到第一中间层；其中，钢渣胶粉混合物为单档钢渣与橡胶粉的混合物；钢渣胶粉混合物、玻璃纤维的总撒布量为10～12kg/m2，钢渣与橡胶粉的重量比为100:1～100:3，钢渣胶粉混合物与玻璃纤维的重量比为100:0.2～100:1；待第一高粘改性乳化沥青破乳后采用胶轮压路机碾压、揉搓，得到第二中间层；在第二中间层表面喷洒第二高粘改性乳化沥青，喷洒量为0.3～0.5L/m2；待第二高粘改性乳化沥青破乳后静置1～2h，即得道路SGF极薄抗滑层。本发明的制备方法简单，对施工条件要求低，且得到的SGF极薄抗滑层具备层厚小，抗滑系数高，性能稳定，经济性能好的优点。
