Ultrathin anti-skid wearing layer and pavement with wearing layer
The invention provides an open-graded drainage type epoxy asphalt ultrathin anti-skid wearing layer which is composed of an open-graded epoxy asphalt mixture with the porosity ranging from 15% to 20%,and the total thickness of the open-graded drainage type epoxy asphalt ultrathin anti-skid wearing layer is about 1 cm. According to the anti-skid wearing layer, epoxy asphalt is adopted to replace common asphalt and thermoplastic modified asphalt, so that the problem that the mechanical strength and durability of a thermoplastic asphalt mixture are reduced due to the comprehensive action of cyclic load, temperature stress and water is solved; the open-graded asphalt mixture with the porosity of 15%-20% is used for achieving the effect of surface drainage, the phenomenon of water drifting generated when an automobile runs at a high speed is reduced, the contact area of a tire and a road surface is increased, and the skid resistance of the asphalt wearing layer is improved; the maximum nominal particle size of the aggregate is 4.75 mm, the thickness of the open graded asphalt surface layer is controlled to be about 1 cm, theultrathin anti-skid wearing layer is formed, the constructioncost is reduced, and the construction recovery time is shortened.
本发明提出一种开级配排水型环氧沥青超薄抗滑磨耗层，该抗滑磨耗层由孔隙率为15％‑20％之间的开级配环氧沥青混合料构成，总厚度约为1cm。该发明的抗滑磨耗层采用环氧沥青取代普通沥青和热塑性改性沥青，解决因循环荷载、温度应力和水的综合作用引发的热塑性沥青混合料力学强度和耐久性降低的问题；使用孔隙率为15％‑20％之间的开级配沥青混合料，起到表层排水的作用，减少汽车高速行驶时产生的水漂现象，增加轮胎和路表的接触面积，提高沥青磨耗层的抗滑能力；集料最大公称粒径为4.75mm，将开级配沥青表层的厚度控制在1cm左右，形成超薄抗滑磨耗层，减少施工的成本，加快施工恢复的时间。
