Embodiment 1

[0069] Using the anti-slip and fog sealing layer material of the present invention to carry out the anti-slip and fog sealing layer construction on asphalt pavement as an example, the anti-slip and fog sealing layer material is made of the following raw materials in parts by weight:

[0070] Hongye 70# road petroleum asphalt 25.0 parts

[0071] 200~500 mesh compound kaolin 15.0 parts

[0072] Asphalt emulsifier MK-06 1.2 parts

[0073] 35.0 parts of tap water

[0074] 0.2 parts of 37% concentrated hydrochloric acid

[0075] 50.0 parts of natural corundum with a particle size of 0.15mm~0.30mm

[0076] The specific implementation process includes the following steps:

[0077] Step 1: Prepare various raw materials according to the ratio of the above-mentioned anti-slip and fog sealing material;

[0078] Step 2: Add asphalt emulsifier MK-06 into water at 50°C, adjust the pH value to 2.0-3.0 with hydrochloric acid, add compound kaolin and stir after fully dissolving, and then ...

Embodiment 2

[0085] The anti-slip and fog sealing layer material is made from the following raw materials in parts by weight:

[0086] Hongye 70# road petroleum asphalt 25.1 parts

[0087] 200~500 mesh compound kaolin 15.1 parts

[0088] Asphalt emulsifier MK-06 1.21 parts

[0089] 35.1 parts of tap water

[0090] 0.21 parts of 37% concentrated hydrochloric acid

[0091] 50.1 parts of natural corundum with a particle size of 0.15mm~0.30mm

[0092] The specific implementation process is the same as in Example 1.

Embodiment 3

[0094] The anti-slip and fog sealing layer material is made from the following raw materials in parts by weight:

[0095] Hongye 70# road petroleum asphalt 32.5 parts

[0096] 22.5 parts of 200~500 mesh compound kaolin

[0097] Asphalt emulsifier MK-06 1.6 parts

[0098] 52.5 parts of tap water

[0099] 0.6 parts of 37% concentrated hydrochloric acid

[0100] 65.0 parts of natural corundum with a particle size of 0.15mm~0.30mm

[0101] The specific implementation process is basically the same as in Example 1, the difference being that in step two, the asphalt emulsifier is added to water at 65°C; in step three, the petroleum asphalt is heated to 135°C, and the soap solution is heated to 65°C; in step six, the amount of spraying Close to 0.45kg / m 2 , construction spraying temperature is 60 ℃.

Abstract

The invention relates to an anti-slide fog seal material and its construction method. The anti-slide fog seal material is obtained by the following steps of: mixing 15-30 parts by weight of composite kaolin, 35-70 parts by weight of water and 1.2-2.0 parts by weight of an asphalt emulsifier, adjusting the pH value into a range required by the corresponding asphalt emulsifier with a pH value conditioning agent, then emulsifying 25-40 parts by weight of hot melt asphalt so as to obtain a stable mixed emulsion, and finally mixing the emulsion with 50-80 parts by weight of sand and conducting stirring. When the anti-slide fog seal material is sprayed on a road surface uniformly by a spraying vehicle, it can bond well with the road surface. Thus, the material not only seals original road surface micro-cracks and voids, plays a strong waterproof role, but also prolongs the road service life. And the sand in the anti-slide fog seal material can substantially improve the anti-slide performance of the road surface.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to an anti-slip and mist sealing layer material and a construction method thereof. Background technique [0002] AEMA (Asphalt Emulsion Manufacturers Association) technology is a road preventive maintenance technology with high maintenance performance and low cost. It sprays the mist sealant material directly on the road surface to quickly provide a black surface for the road; it can seal small cracks and potholes, prevent moisture from entering the surface pores, and improve the waterproof performance of the surface; it can renew or restore the surface Aged asphalt can prolong the service life of the road surface; in addition, the fog seal layer stabilizes the loose aggregate on the road surface to prevent further loosening, which can protect or repair the binder lost by the road surface due to aging, and reduce the impact of aging and weathering influence on pavement per...
