Problems solved by technology

[0003] At present, there are many fog seal materials at home and abroad. However, it is found in practical engineering applications that they all have the disadvantages of wear resistance and poor adhesion to the road surface during use. After one to two months of use , the fog seal material is very easy to be worn off and taken away by driving, and there are basically no traces of the used fog seal material on the road surface

Abstract

The invention relates to a mist sealing layer material and a preparation method thereof. The fog seal material has the disadvantages of poor wear resistance and poor adhesion to the road surface during use, and it is easy to be worn off and taken away by driving during use. In the present invention, after heating and melting the asphalt and the asphalt regenerant, they are mixed with a penetration aid, and the aqueous solution of the asphalt emulsifier and the molten mixture are mixed to prepare the A component of the mist sealing layer material; the water-based epoxy resin and the water-based epoxy resin curing agent are mixed. Mixing to obtain the B component of the mist sealing layer material; mixing 10-50 weight parts of the A component and 10-40 weight parts of the B component evenly to obtain the mist sealing layer material. The invention has good adhesion to the original road surface, excellent wear resistance, long maintenance time, strong permeability, and has a good function of regenerating the aged asphalt of the pavement. performance.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, and in particular relates to a fog sealing layer material and a preparation method thereof. Background technique [0002] Fog sealing layer technology is a road preventive maintenance technology with high maintenance performance and low cost. It sprays the mist sealing material directly on the road surface to quickly provide a black surface for the road; it can seal the pores and micro-cracks on the road surface, preventing moisture and air from entering the road structure and causing damage to the road structure. Small cracks on the road surface can heal automatically; it can activate the aged asphalt, renew and restore the oxidized asphalt paste on the surface, and prolong the service life of the road surface; Preventing its further loosening can protect or repair the binder lost by the pavement due to aging, and reduce the impact of aging and weathering on the performance of the pave...
