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
The invention belongs to the material technology field, be specifically related to the used mist seal of road preventive maintenance bitumen emulsion admixture and using method thereof.
Background technology
Mist seal full name is vaporific seal, is a kind of novel pavement preventive maintenance technology.The mist seal is by adopting special-purpose mist seal pitch sprinkling car, one deck fluid materials that on top course, evenly sprays, its objective is in order effectively to seal the road and show hole, water proof anti-seepage, stablize discrete aggregate, repair ageing paving, improve appearance of a street road looks, thereby realization prolongs service life of road surface, saves the maintenance fund.Common mist sealing material mainly contains emulsified bitumen, modified emulsifying asphalt and road maintenance agent thereof etc., because that material when spraying, presents is vaporific, therefore is referred to as the mist seal.
The quality of mist sealing material performance directly has influence on mist seal construction quality, should satisfy following technical requirements usually: (1) adhesion property, bitumen emulsion and the protobitumen road surface particle that the mist seal forms wrap evenly, bond firmly.Be difficult for softening, bellding or glued to fall to be exposed to light accidentally not during summer high temperature, do not have obscission when winter low temperature or rainy day, do not influence former pavement skid resistance, abrasion resisting performance by wheel.(2) anti-water permeation performance, the bitumen emulsion that the mist seal forms can fill fast, infiltrate in road table hole and the slight fissured crack, road surface, stablizes discrete particle, and sealing road surface hole strengthens the anti-bad performance of damage by water on road surface.(3) asphalt-regenerating performance, the bitumen emulsion rapid osmotic that the mist seal forms are in aging brea bed, and the component of mediation aged asphalt makes former road surface aged asphalt obtain regeneration.(4) workability, mist seal bitumen emulsion system is stable, no segregation phenomenon, guarantee to spray evenly, the color and luster unanimity, because mist seal speed of application is very fast, materials supply require in time simultaneously, and the viscosity of mist seal bitumen emulsion or pitch solid content can be according to the road conditions different situations with using with accent, and it is fast to possess moulding, open to traffic morning etc. performance.
At present, the mist sealing material selects for use common emulsified asphalt more relatively, in the engineering practice process, find to exist following mass defect: (1) emulsified bituminous materials and original old pavement bad adhesion, behind the open to traffic, mist seal bituminous material is ground, glues by driving vehicle easily; (2) the emulsified bituminous materials seepage force is poor, can't be penetrated in the old pavement, and hole is shown on the filling road, waterproof effect is poor; (3) existing mist seal emulsified bituminous materials does not have the function that makes old pavement aged asphalt material regeneration; (4) existing mist seal emulsified bituminous materials de-emulsification speed is slow, and the close traffic time is long; (5) behind the existing mist seal emulsified bituminous materials breakdown of emulsion, color is more of light color than newly-built road surface, influences appearance effect.
