Improving the thermal effect of urban pavement is one of the ways to solve the urban heat island effect and the problem of urban near-surface human comfort. In this paper, the temperature field of the pavement under different thermal properties was simulated by the fluid-solid coupling model. According to the radiant heat effect of the road surface and the calculation method of convective heat transfer effect, the all-day heat effect of the asphalt pavement under different thermal properties parameters is calculated. The influence of thermal properties on the near-surface exothermic effect of urban pavements was analyzed. The optimal combination of pavement material parameters was obtained by orthogonal test method to reduce the urban heat island effect,
