Large scale implementation of cool asphaltic and concrete photocatalytic pavements

Extensive monitoring strategy of in situ measurements in the area

Surface temperatures reduction up to 7.5 °C and 6.1 °C respectively in the summer period, while the peak drop was up to 11.5 °C

The maximum air temperature reduction could reach 1.5 °C.

Ageing phenomena may reduce substantially and up to 50% the mitigation potential of cool asphaltic materials.
