Asphalt pavement fine sealing layer and construction method thereof

Abstract

According to the fine solid sealing layer for the asphalt pavement and the construction method of the fine solid sealing layer, a three-layer sandwich structure is adopted, the wear-resistant gravel layer is arranged in the middle, the anti-skid performance of the wear-resistant gravel layer and the bonding performance of the bonding layer and the original pavement can be fully exerted, the toughness of resin is improved by adding polydimethylsiloxane, and the service life of the resin is prolonged. The resin is not easy to crack under the action of cyclic shearing, the bearing capacity of the resin is improved by matching with the addition of nano aluminum oxide, and the resin serving as a bonding layer has excellent bonding strength and an effect of blending with a wear-resistant gravel layer, so that the service life of the road surface is prolonged, and the service life of the road surface is prolonged. And the used bonding layer material and the stable layer material are both emulsified asphalt materials, so that compared with solvent asphalt, the production cost is greatly reduced, and meanwhile, low carbon, environmental protection and safety in use are realized.
