description | The utility model provides a phase-change self-temperature-regulating permeable asphalt pavement structure, which comprises permeable asphalt and a phase-change self-temperature-regulating structural layer which are sequentially paved above a roadbed from bottom to top, and can automatically regulate the temperature of the pavement on the premise of keeping good drainage capacity. The adaptive capacity of the permeable asphalt mixture to the temperature can be improved, the high and low temperature extreme values and the change amplitude of the temperature of the permeable asphalt layer are actively regulated and controlled by using a phase change energy storage temperature regulation mechanism and the characteristics of releasing phase change latent heat in the cooling process and storing the phase change latent heat in the heating process, and the environmental adaptive capacity of the pavement structure is improved; according to the pavement structure, the purpose of stabilizing the temperature difference |
