Description

technical field [0001] The present invention relates to a composition for adjusting the temperature of asphalt pavement, its preparation method and use, in particular to a thermosetting methacrylic resin-based composition for adjusting the temperature of asphalt pavement, its preparation method and use. Background technique [0002] Asphalt pavement has good flatness, driving comfort and noise reduction ability, so it is widely used in various high-grade pavements. Asphalt is an endothermic material, which absorbs a wide range of wavelengths of solar radiation, and a large amount of heat accumulates in the asphalt surface layer, which increases the temperature of the road surface. This high temperature environment can easily lead to the urban "heat island effect", which seriously affects the atmospheric temperature. Therefore, there is an urgent need to develop a composition for adjusting the temperature of asphalt pavement that not only satisfies the temperature adjustment...
