Anti-rutting pavement structure under high temperature and heavy load conditions of heat reflective fog seal material

Abstract

The invention discloses an anti-rut pavement structure of a heat reflection fog sealing layer material for high temperature heavy duty conditions. The structure is made by mixing 0.5-3 parts by mass of hollow ceramic particles with 7-9.5 parts by mass of emulsified bitumen. The anti-rut pavement structure of the heat reflection fog sealing layer material for high temperature heavy duty conditions sequentially comprises an upper surface layer, a medium lower surface layer and a base layer; and the upper surface layer is an SMA-13 bitumen mixture layer, the medium lower surface layer is an HMAC-20 high modulus bitumen mixture layer, the base layer is an LSAM large particle size bitumen mixture layer and a cement stable crushed rock layer, and the surface of the upper surface layer is coated with the heat reflection fog sealing layer material.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a heat-reflecting fog sealing layer material for road surfaces, and a rutting-resistant road surface structure under high-temperature and heavy-load conditions using the heat-reflecting fog sealing layer material. Background technique [0002] Rutting is the accumulation of non-recoverable strain on the subgrade and pavement under repeated traffic loads. [0003] Deformation and compaction deformation under the action of driving load are a unique damage phenomenon of asphalt pavement. According to the survey in the United States in the 1970s, about 40% of the pavement damage was caused by rutting on interstate and major highways; the Japanese survey in the 1980s showed that the pavement damage caused by rutting was as high as 80%. In our country, in recent years, expressway construction has developed rapidly, and large areas of early rutting damage have appeared in var...

AI Technical Summary

Problems solved by technology

After the use of these materials and methods, the surface temperature of the asphalt pavement is reduced to a certain extent, and the hazard of rutting is reduced, but the disadvantage is that the organic matter of the heat reflective material accounts for a large proportion, which not only pollutes the environment, but also has a high cost. affect its promotion
