P a g e | 44 Maltene Replacement Technology (MRT) reintroduces to the aged binder, exact molecular components (maltene fractions) lost to manufacturing related thermal stress and in-service oxidation, extending pavement life by years. In an on-going study of MRT in Charleston, South Carolina, treated pavements didn’t return to their original, untreated dynamic viscosity until year seven (Figure 21) . 94 The impact from MRT cuts both paving budgets and averts asphalt manufacturing emissions by as much as 50% by significantly stretching-out repaving cycles. 95 96 97 98 99 100 The carbon savings from MRT is ~1,500 tons per mile (CLM) every (full) repaving cycle . 101 Maltene Rejuvenator After 4 Years Source: Pavement Technology, Inc. 94 Multi-year MRT Sustainability Study: Charleston County (SC): Pavement Technology, Inc.; APART. 95 Vitale J and Siddiqi K, The Feasibility of Asphalt Pavement Rejuvenator Applications, 2016. 96 Boyer RE, Asphalt Rejuvenators Fact or Fable, 2000. 97 Durante M, Maltene-Based Rejuvenators Restore Flexibility, Quell Oxidation Effects, Pavement Preservation Journal , Spring 2020. 98 Golden J, A Data-Driven Condition Assessment for Asphalt Rejuvenation Using Maltene Replacement Technology, September 2021. 99 Chehovits J and Galehouse L, Energy Usage and Greenhouse Gas Emissions of Pavement Preservation Processes for Asphalt Pavements, Transportation Research Board , 2010. 100 Report of Phase II Pavement Rejuvenator Study, City of Orlando, Ardaman & Assoc., 1997. 101 Chehovits J and Galehouse L; BlackwallPartners LLC .
