• Abstract:
  This project investigated potential concrete bridge deck crack and surface sealers, and their optimum application timing. The purpose of this project was to determine if there were better products than what the South Dakota Department of Transportation (SDDOT) was using (i.e. – linseed oil surface sealer and epoxy crack sealer) that can be applied by SDDOT maintenance personnel. The objectives and tasks for this project were accomplished by gathering and evaluating agency, field, laboratory, and literature data. A major portion of this research project focused on determining the optimum timing for treatment application. The results indicate the following: (1) SDDOT should discontinue use of linseed oil as a penetrating sealer. (2) SDDOT should adopt penetrating sealers such as silanes/siloxanes/siliconates for surface sealing. (3) SDDOT should continue to use crack sealers such as reactive methacrylates, modified polyurethanes, and epoxies with low viscosity (i.e. - = 15 cp).
