Abstract

The invention provides a fog sealing layer asphalt emulsion admixture and a use method thereof. The admixture consists of the following raw materials in percentage by mass: 30 to 60 percent of asphalt reclaiming agent, 5 to 10 percent of asphalt reclaiming aid, 1 to 3 percent of penetrant, 1 to 5 percent of emulsifier, 2 to 8 percent of tackifier, and the balance water. When the admixture is added into a fog sealing material, the infiltrability of the fog sealing layer asphalt emulsion can be reinforced, thus the emulsion can be quickly filled in pores and microcracks on road surfaces, so that the water seepage resistance of the pavement is reinforced, and the asphalt pavement is prevented from water damage; the admixture can be quickly infiltrated to an aged asphalt layer to harmonize the components in the aged asphalt, so that the aged asphalt is regenerated; the admixture has strong bonding capability with the asphalt pavement, after traffic is open, the fog sealing layer material and the pavement are bonded firmly, and the admixture is not easy to adhere to vehicle wheels; and the molded admixture has accordant color with the newly built pavement, thus the road appearance is beautified.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an asphalt emulsion admixture for fog seal layer used in road preventive maintenance and a using method thereof. Background technique [0002] The full name of the fog seal is the fog seal, which is a new preventive maintenance technology for road surfaces. The fog seal layer is a layer of fluid material evenly sprayed on the pavement surface layer by using a special fog seal layer asphalt sprinkler. Improve the appearance of the road, so as to prolong the service life of the road surface and save maintenance funds. Common mist seal materials mainly include emulsified asphalt, modified emulsified asphalt and road maintenance agents, etc., because when the materials are sprayed, they appear in the form of mist, so they are collectively referred to as fog seal. [0003] The performance of the fog seal layer material directly affects the quality of the fog seal layer...
