• Abstract:
  Asphalt pavements features good performance and relatively low construction and maintenance ; costs. However, the black color of asphalt binder implies that the sunlight is not reflected but ; absorbed, which raises the temperature of the asphalt pavement and impairs its long-term durability. ; This project investigated the use of innovative polymeric thermochromic materials into asphalt ; binder to develop thermochromic asphalt binder, which will reduce the surface temperature of ; asphalt pavement during summer and lead to improved durability. Comparison measurements have ; found that the surface temperature of thermochromic asphalt binder is lower than that of the ; conventional asphalt binder. Besides the cooling effects, study showed that the surface temperature ; of thermochromic asphalt was higher than regular asphalt under low temperature. This means ; thermochromic asphalt can delay ice formation on the surface of road than traditional asphalt, which ; is an important potential benefits for road safety in cold regions The project conducted a pilot study ; to gauge the potential of thermochromic asphalt concrete to improve the durability of the pavement, ; reduce the environmental impacts, and mitigate ice related safety issues on the road.
