• Abstract:
  Four epoxy overlay systems were applied to concrete bridge decks in north Louisiana to evaluate their performance as skid resistant surfaces primarily and also as concrete sealers. Dural Flexolith, Poly-Carb Flexogrid, and Con/Chem Cono/Crete were placed on three separate bridge decks; sand and Dural epoxy were placed on the fourth deck. Skid tests were taken with the British Portable Tester and the E-274 Skid Trailer; sealing characteristics of each system were checked with electrical resistivity measurements. ; An initial evaluation determined that both Dural Flexolith and Poly-Carb Flexogrid (broadcast systems) provided very good skid resistant surfaces. The use of sand and Dural epoxy also provided a good surface for skid resistance. The mortar system (Con/chem Cono/Crete) produced low skid numbers initially.
