Anti-slide fog seal material and its construction method
ActiveCN102815892AImprove skid resistanceAvoid the problem of insufficient skid resistanceIn situ pavingsKaolin clayRoad surface
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.
