P a g e | 111 Photocatalytic pavements are rain displacing / ice-build inhibiting for inclement weather-related safety improvements for roadways. 237 ✓ Water Purification - photocatalytic surfaces also are stormwater purifying as the combination of cooler pavements with depolluting properties are antibacterial, antiviral, and anti-plastic. ✓ Microplastic Decomposition is 99% efficient with TiO 2 . 238 239 Dangerous airborne and aquatic plastic pollution deposition into our environment estimated to be 85% sourced from roadway tire wear (RAMP TWP ), brake-pad wear (RAMP BPW ), and polymer modified asphalt (RAMP PMA ) degradation. One toxin, PFAS , is commonly used on tires as a protective coating and it is an emerging cause of concern for agencies as much of the reported contaminations are coming from the roadway.
