Cool pavement systems as a hot mix asphalt alternative is encouraged by state legislation in California.
The Water Conservation PPN is highlighting two ways cool pavement technology save water. First, reducing paving temperature reduces water evaporation from soil adjacent to paving. Also, plants in close proximity to pavement lose water quickly, when compared to plants adjacent to cool pavements. In addition to positive air quality impacts (carbon, VOC’s, temperature, etc.), water conservation is a good reason to look at new resin based paving technology. This will be explored here through a case study of a project in Northern California: Lake Merritt located in the middle of Oakland, CA.
