Project description

MDOT currently waits 28 days after the placement of all concrete decks, rigid overlays, and patches on bridge decks before placing epoxy overlays and sealants. Often this extended period conflicts with traffic and weather limitations. With more information on the crack development and moisture release characteristics of MDOT standard concrete materials (Grade D, DM, SFMC, LMC, etc.) and special/patching mixtures MDOT could potentially reduce the time required between placements.
