Lightweight asphalt pavement anti-skid wearing layer adopting ceramsite aggregate and preparation method of lightweight asphalt pavement anti-skid wearing layer
The invention relates to a lightweight asphalt pavement anti-skid wearing layer adopting ceramsite aggregate and a preparation method of the lightweight asphalt pavement anti-skid wearing layer. The lightweight asphalt pavement anti-skid wearing layer comprises the following components in parts by mass: 80-90 parts of ceramsite, 10-15 parts of asphalt, 5-10 parts of coarse aggregate and 5-8 parts of mineral powder, and the thickness of the light asphalt pavement anti-skid wearing layer is 8-12mm. Compared with the prior art, aging caused by factors such as ultraviolet rays, oxidation and temperature change can be resisted, and the wear resistance of the pavement is improved; meanwhile, due to the lightweight performance of the ceramsite, the burden of a road structure is relieved, pavement settlement and damage are reduced, non-communicated closed air holes in the ceramsite are beneficial to reducing the water absorption rate, reducing water permeation and preventing aggregate abrasion under the action of tires, the anti-skid effect is better and more remarkable, and the service life of a road is prolonged.
本发明涉及一种采用陶粒骨料的轻质沥青路面抗滑磨耗层及其制备方法，所述轻质沥青路面抗滑磨耗层包括以下质量单位的各组分：80～90份陶粒、10～15份沥青、5～10份粗集料、5～8份矿粉；所述轻质沥青路面抗滑磨耗层的厚度为8～12mm。与现有技术相比，本发明可以抵御紫外线、氧化和温度变化等因素引起的老化，提高路面耐磨性；同时陶粒的轻质性能减轻了道路结构的负担，有助于减少路面沉降和损坏，其内部的非连通封闭气孔有助于减少吸水率，降低水分渗透，防止轮胎作用下的集料磨损，使抗滑效果更佳显著，延长道路的使用寿命。
