Overlays with Rapid Setting Cement and a Liquid Low P Admixture

The Virginia Department of Transportation (VDOT) has long relied on latex-modified concrete (LMC) overlays with rapid setting cement to extend the service life of bridge decks by providing low permeability and early strength gain. However, advancements in concrete admixture technology offer alternative solutions that may enhance durability, workability, and sustainability. This study proposes replacing the latex modifier in LMC overlays with Liquid Low P admixture. The research will evaluate the feasibility of this substitution by assessing permeability, strength, length change, freeze-thaw durability, and constructability. The project will involve field evaluations to compare the performance of Low P modified concrete to traditional LMC. If successful, this approach could streamline overlay placement, reduce material handling complexities, and provide a cost-effective alternative for VDOT bridge deck rehabilitation projects.
