Abstract

The too high temperature of cement concrete pavement is both an important cause of pavement diseases and an important factor exacerbating the heat island effect. To reduce the temperature and temperature gradient of high-temperature cement pavement panels in summer and alleviate the urban heat island effect, this paper prepared a reflective coating whose binder is fluorosilicon-modified acrylic acid, conducted experimental research, and measured the pavement temperature and temperature gradient before and after utilizing the coating. Meanwhile, it conducted theoretical analysis, calculated the influence of reflective coatings on the warping deformation of pavement panels, and analyzed the effect of coatings on the heat release of pavement, with the influence of coatings on urban heat island effect explored. The results show that under high-temperature weather in summer, the highest temperature of the pavement is 59℃, and the maximum positive temperature gradient is 96.1℃/m. Additionally, the reflective coating can reduce the temperature of cement concrete pavement by about 9℃, and reduce the maximum positive temperature gradient by 31.7℃/m. Before applying the reflective coating, the maximum warping stress of the pavement reaches 2.16 MPa, and after applying the reflective coating, the maximum warping stress is 1.7 MPa, a decrease of about 30%. The utilization of reflective coatings can effectively reduce the heat emitted by cement pavement to the air by about 15%, thus alleviating the heat island effect in summer to some extent.
