Palm oil shell aggregate as cool pavement by replacing fine aggregate

Urban Heat Island (UHI) phenomenon is due to ever increasing environment temperature in cities compared to the adjacent non-urbanized areas. One of the major contributors to UHI is asphalt pavement because of its tendency to absorb high amount of heat due to its dark color. Cool pavement is known as...
