P a g e | 104 Carbon (and Plastic) Capturing Pavements Pavement Technology, Inc. has over forty years of experience in the pavement preservation industry, serving America’s largest public works agencies and transportation administrators. At the Earthx2019 environmental symposium, PTI formally introduced our state-of-the-art mobile source pollution-reduction and solar reflective “photocatalytic pavement” solutions after years of both field and laboratory testing success. 221 Agencies have utilized PTI’s core technology – maltene replacement 222 for decades to extend asphalt pavement life through molecular revitalization. MRT has been shown to extend pavement life by as much as 50% (or more), cutting both repaving budgets and asphalt manufacturing and construction (embodied) emissions by the same through materially stretching-out repaving cycles. A recent carbon savings analysis on the greater than 35,000 lane miles PTI has treated with MRT over our history concluded that the technology saved 28 million metric tons of carbon (CO 2 e), worth $5.3 billion in societal value by current Biden administration estimates. That is in addition to the estimated $1.5 billion in direct financial savings to agencies and taxpayers. 223 Our PlusTi TM family of road preservation products build upon the MRT success by adding photocatalytic materials which promote certain use phase decarbonization and other environmental benefits including direct pollutant removal, cooler pavements, and better pavement hydrophilicity in addition to traditional pavement preservation. PlusTi TM “smog-eating” road products now have over five years of field performance testing. Select customers include Cincinnati, Akron, Orlando, Orlando International Airport, Raleigh, Charlotte, Durham, Charleston, Phoenix, Tucson, Tempe, and Austin. They have been tested by the Florida Department of Transportation (FDOT) and approved for USGBC LEED and ISI ENV accreditation. PlusTi TM PhotoCatalytic Technology (PCT) is supported by U.S. and Canadian patents. 221 Zollinger DG and Joshaghani A, Laboratory Investigation of the Effect of TiO 2 Topical Treatments on Concrete and Asphalt Samples , Texas A&M Transportation Institute, September 2018. 222 GotMaltenes? www.pavetechinc.com/got-maltenes/ . 223 BlackwallPartners LLC; EPA; NCPP; and company reports.
