Construction process of super-viscous wearing layer
The invention belongs to the technical field of road construction, and particularly relates to a super-viscous wearing layer construction process which comprises the following steps: S1, preparing construction equipment and materials; s2, determining application types and dosages of the modified emulsified asphalt, the fiber, the aggregate and the additive material through tests; s3, preparation work before construction; s4, on the day of construction, the road surface is cleaned, a construction prompt sign is set, meanwhile, the readiness of materials and equipment is determined, and it is guaranteed that construction is errorless; s5, performing one-time test road construction operation on a section of road surface, and adjusting construction parameters according to the effect; the super-viscous wearing layer has high abradability, high adhesiveness, high waterproofness and high stress absorption and stress diffusion capacity, the tensile strength, the shear strength, the compression strength and the impact strength of the wearing layer are effectively improved, the skid resistance of the pavement can be remarkably improved, and meanwhile the continuous construction process greatly shortens the maintenance time of the asphalt road.
本发明属于道路施工技术领域，尤其是一种超粘磨耗层施工工艺，包括S1、准备施工设备及材料；S2、通过试验测定改性乳化沥青、纤维、集料、添加剂材料的应用种类及其用量；S3、施工前准备工作；S4、施工当日对路面进行清扫并设置施工提示标志，同时对材料以及设备的就绪进行确定，保证施工无误；S5、先在一段路面上进行一次试验路施工作业，并根据效果对施工各参数进行调整；本发明中的超粘磨耗层具有高磨耗性、高黏附性、高防水性、高度应力吸收和应力扩散能力，有效地提高了磨耗层的抗拉、抗剪、抗压和抗冲击强度，能显著提升路面抗滑能力，同时该连续施工工艺极大地缩短了沥青道路养护的时间。
