Ultrathin road wearing layer and construction method thereof
The invention relates to a road ultra-thin wearing layer and a construction method thereof, an emulsified asphalt layer mixture for an emulsified asphalt layer comprises modified glass fiber, sodium alginate and high-viscosity modified emulsified asphalt, and an ultra-thin wearing layer mixture for the ultra-thin wearing layer comprises filler, SBS modified asphalt, sodium alginate, modified glass fiber and aggregate; micro textures are provided through multiple broken stone contents, a macro structure is provided through coarse aggregate gap gradation, and good short-term anti-skid performance and long-term anti-skid performance are guaranteed; the modified glass fibers are respectively added into the mixture of the emulsified asphalt layer and the ultra-thin wearing layer, so that the porosity of the ultra-thin wearing layer of the road is reduced to below 6% while the tight connection between the emulsified asphalt layer and the ultra-thin wearing layer is enhanced, no rainwater is left in the pavement, the water stability can be effectively improved, and the durability is good; the optimal paving thickness can be reduced to 2cm, the minimum limit thickness can reach 1.5 cm, and the thickness is reduced by more than 25% compared with the thickness of 2.5 cm, so that the project investment is effectively saved.
本发明一种道路超薄磨耗层及其施工方法，乳化沥青层用乳化沥青层混合料包括：改性玻璃纤维、海藻酸钠和高黏度改性乳化沥青，超薄磨耗层用超薄磨耗层混合料包括：填料、SBS改性沥青、海藻酸钠、改性玻璃纤维和集料；通过多碎石含量提供微观纹理、粗集料断级配提供宏观构造，保证了良好的短期抗滑性能和长期抗滑性能；分别在乳化沥青层、超薄磨耗层混合料中加入改性玻璃纤维，加强乳化沥青层、超薄磨耗层间连接紧密的同时，使道路超薄磨耗层的孔隙率降至6%以下，路面内部雨水不残留、可有效改善水稳定性，具有良好的耐久性；最佳铺装厚度可减薄至2cm，极限最薄可达1.5cm，比2.5cm厚度减薄25%以上，有效节约工程投资。
