技术概述抗滑型雾封层是一种新型高速公路沥青路面预防性养护技术,利用专用设备将具有良好渗透性的油剂型雾封层材料和铁钢砂均匀的洒布到沥青路面上,雾封层材料可以填封微小裂缝和表面空隙,起到防水和抑制松散的作用,防止路面材料进一步老化。铁钢砂可以增大路表面的粗糙程度,起到提高路面摩擦系数、保证行车安全的作用。该工艺可提高路面抗滑性能、避免水损害,达到保护路面结构,延长路面使用寿命的目的,是一种经济有效的预防性养护措施。
Technical Overview Anti-slip fog seal is a new type of highway asphalt pavement preventive maintenance technology, the use of special equipment will have good permeability of oil-based fog seal material and iron steel sand evenly spread asphalt pavement, the fog Sealing material can seal tiny cracks and surface voids, play a waterproof and inhibit the role of loose, to prevent further deterioration of pavement materials. Steel grit can increase the roughness of the road surface, play a role in improving road friction coefficient, to ensure traffic safety. The process can improve the skid resistance of the road surface, avoid water damage, achieve the purpose of protecting the road surface structure and prolonging the service life of the road surface, and is a cost-effective preventive maintenance measure.
