Learn More About the Program
In 2020, the city selected portions of eight neighborhoods, one in
each City Council district and part of the parking lot in Esteban Park, to
receive cool pavement treatment. The asphalt coating was applied to areas already
in need of pavement preservation. The city then partnered with ASU researchers
to conduct scientific tests of the cool paved areas, studying how it performed
and how it might be used to mitigate the urban heat island effect.
Scientific data collection during year one of the study included thermal imaging through helicopter flyovers, temperature sensors embedded in the pavement surface, and other advanced instruments to conduct testing across various heat metrics. ASU researchers also developed MaRTy (derived from 'Mean Radiant Temperature'), a specially designed mobile weather station that evaluates the human experience of heat by measuring 3D mean radiant temperature, air temperature, relative humidity, and wind speed and direction. Additionally, a vehicle equipped with air and surface temperature sensors traveled over the treated areas to gather data during four times of the day.
What is cool pavement?
It is a water-based asphalt treatment that is applied on top of the existing asphalt pavement. It's made with asphalt, water, an emulsifying agent (soap), mineral fillers, polymers and recycled materials. It contains no harmful chemicals and is compatible with traditional asphalt.
