Evaluation of Pyrament Bridge Deck Overlay
The Oklahoma Department of Transportation (ODOT) has been using high density Portland cemet (HDPC) overlays for more than twenty years to minimize spells and delaminations in concrete. Since HDPC overlays were introduced, additives were incorporated into these mixtures to increase concrete strength and durability as well as decrease the time needed for curing. Pyrament, marketed and manufactured by Lonestar Industries, is a concrete comprised of 65% Portland Cement, 30% fly ash, and 50% trademark additive. In 1990, Pyrament concrete was used on a bridge reconstruction project. The Research, Development, and Technology Transfer (RD&T) of ODOT monitored the construction process and documented their findings. In order to assess the long term performance of Pyrament, RD&T has been evaluating this bridge deck since the completion of construction at regular intervals.
