Surface Temperature Reduction of Porous Concrete Pavers Using a Water Retention Layer

Porous pavements are now used to reduce urban heat even though previously it was designed specifically stormwater runoff. To qualify the pavement as a cold pavement, needs be modified either evaporative reflective and storage pavement. This study porous concrete pavers by adding wetted retention layer underneath investigated temperature reduced. Three materials of water layers were material with higher selected. The changes studied using selected different thicknesses. result shows that felt wool absorbed more compared palm oil fiber geotextile. While for selection thickness, 8 mm thick due its optimal evaporation rate gives reduction on block 4 12 thick.
