Method for paving anti-rut anti-skid pavement coating

Abstract

The invention provides a method for paving an anti-rut anti-skid pavement coating. The method for paving the anti-rut anti-skid pavement coating comprises the following steps of construction preparation, earlier-stage processing, primer preparation, primer coating, aggregate spreading and recycling, finishing coat preparation and coating, maintenance, and final cleanup. Primarily, the surface layer of pitch is evenly coated with acrylic resin, high-abrasion-proof-value aggregate is paved on the surface of the acrylic resin, the aggregate and the primer are well combined, a nanofiller in the primer or the finishing coat enables the coating to be strong in heat refection capacity, the surface temperature of the coating is lowered by 5-12 DEG C in the high-temperature weather, therefore, the pavement temperature is lower than the pitch softening point, and the problem of the pavement rut is effectively solved. The friction coefficient of the coating is higher than that of an ordinary pitch pavement, good in skid resistance, and capable of improving the abrasive resistance of a pavement and enabling the color of the pavement to keep attractively bright-colored for a long time.

Description

technical field [0001] The invention relates to a construction method of asphalt pavement of urban roads, in particular a pavement method for coating anti-rutting and anti-slip pavement. Background technique [0002] Asphalt mixture is a viscoelastic material, and its physical and mechanical properties are closely related to temperature. Asphalt is a heat-absorbing material with a high absorption rate of solar radiation, usually reaching 90%-95%. The practice of road use shows that under normal vehicle load conditions, the permanent deformation is mainly when the air temperature is higher than 25°C-30°C in summer, that is, the road surface temperature of the asphalt pavement reaches 40°C-50°C, which has reached or It is easy to occur when the temperature exceeds the softening point of road asphalt, and as the temperature increases and the load increases, the deformation increases. On the contrary, below this temperature, no serious deformation will occur. Many pavement hi...

AI Technical Summary

Problems solved by technology

In hot summer, the surface temperature of the asphalt pavement is often higher than the softening point of the asphalt, and the bearing capacity decreases, so it is easy to form ruts under heavy loads, causing uncomfortable driving and affecting the service life of the asphalt pavement
