Abstract: Phase change material is a kind of excellent latent heat energy storage material, which is widely used in the fields of space, building and energy saving. However, the application of phase change materials in road engineering is still in its primary stage. Research status of common phase change materials and composite phase change materials synthesis methods and technical requirements of phase change materials, as well as phase change materials in asphalt mixture and cement concrete are expounded, and the phase change material in road engineering in the direction of development.
