Advances in concrete technology have allowed Flowable Fibrous Concrete (FFC) inlays to be an option for pavement preservation through rapid placement, thin-lift construction, durability, and material ductility. By incorporating titanium dioxide (TiO_2) cement, these FFC inlays can also mitigate vehicular greenhouse gas emissions and the Urban Heat Island (UHI) as well as meet structural requirements. A concrete mix incorporating this modified FFC was lab-tested for strength and fracture properties at 7 days and was found to be acceptable for pavement preservation applications. The FFC albedo was measured as 0.26 and the predicted hourly surface temperatures of hypothetically-aged asphalt concrete pavements with and without the FFC inlay were compared over a ten-year period using weather data from Chicago, IL. With a lower surface temperature in 94% of daytime hours, the inlay was effective in mitigating daytime UHI but less effective in nighttime.
