Cooling the Planet One Roadway at a Time
The reallocation of land due to urbanization, when coupled with ever-rising vehicular emission levels, is intensifying the Urban Heat Island effect in our cities. Heat build-up is particularly prevalent in America’s impoverished inner city communities, where environmental inequities exacerbate health-related concerns in adjacent densely populated communities.
Factors Contributing to Urban Heat Island Effect
In addition to the ecological and health concerns related to warm temperatures, the UHI effect increases energy demand.
PROVEN: Cool Substrates Help Mitigate UHI
Conventional paving materials can reach peak summertime temperatures of 150°F or more, transferring excess heat to the air above them as well as heating stormwater run-off, adversely affecting not only the health of surrounding communities but the watershed ecology.
The solar-reflective properties of the PlusTi family of cool pavement smog-eating-road solutions can reduce infrastructure surface temperatures and emissivity by trippling the solar reflectance value (SRI) of pavements. Roadways, runways, bridges and other infrastructural components treated with PTI’s TiO2’s-based Photo Catalytic Technology (PCT) provide a solar-reflective top boundary that reduces pavement heat absorption and related Radiative Forcing (RF).
