In many cities, pavements (roads, platforms, pavement around buildings, parking areas,etc.) represent the largest percentage of a community’s land cover (30-40%),compared with roof and vegetated surfaces.
Cool pavements are reflective/permeable pavements that help lower surfacetemperatures and reduce the amount of heat absorbed into the pavement. Solar reflective "cool" pavements stay cooler in the sun than conventional pavements.Pavement reflectance can be enhanced by using reflective aggregate, reflective or clearbinder or reflective surface coating.
Permeable pavements—which allow air, water, and water vapour into the voids of apavement, keeping the material cool when moist.
Cool pavements may include:
This NBS can be used at roads, platforms, pavement around buildings, parking areas etc. It can be easily replaced with any other pavement material when necessary.
The period of recovery of the initial economic investment of the NBS is between 0 and 5 years.
