Study on the performance of thermal reflection coating for asphalt pavement

摘要

The thermal reflection coating applied on the surface of asphalt pavement can effectively reduce the temperature by 5-10℃ in high temperature seasons such as in summer, which can obtain an even better effect when it is used on porous asphalt pavement with good drainage ability;the thermal reflective pavement can also decrease the air temperature above the surrounding areas, thereby assisting in alleviating the urban heat island effect;in accordance with the study on the comprehensive onroad performance of the paint, it can be concluded that the pavement painted by thermal reflection coating has a good abrasion resistance;as the increase usage of the coating, the skid resistance of which is reduced subsequently, and when the coating is applied on the specimen with dense gradation, the skid-resistant aggregate should be added, which can significantly improve the skid resistance of the pavement;the cooling effect of the thermal reflective pavement can enhance the dynamic stability and therefore improve the high-temperature stability of the pavement.
