Project description

There will be four short-term projects: a) Mix Rejuvenator Synthesis - the objective is to identify the types of asphalt mix rejuvenators available and their performance to date; b) Concrete Pavement Restoration (CPR) for Bonded Concrete Overlays of Asphalt - the objective is to develop and publish a synthesis of best practices being used by NRRA state members in repairing Bonded Concrete Overlays of Asphalt; c) Service Life Enhancement of Substrates Overlaid with Thin Overlays - the objective is to determine the service lives for the three non-structural overlays and deduce the service life enhancements that these non-structural overlays contribute to the identified flexible substrates on which the overlays were placed based on the pavement management data from the NRRA member states; d) NRRA Spray on Rejuvenator Synthesis - the objective is to document the field projects constructed to evaluate spray on rejuvenators by NRRA member states, National Center for Asphalt Technology (NCAT), NCHRP, Minnesota cities and counties, including recent research projects performed by Missouri DOT with Applied Research Associates, Inc.
