Traditionally, Oklahoma Department of Transportation (ODOT) specifications and the high quality of the limestones and shales used for the production of Portland cement concrete (PCC) materials have prevented any significant alkali-silica reactions (ASR) on their structures or pavements. The materials that could affect ASR include: Portland cement, fly ash, coarse aggregate, fine aggregate, and water. This report contains location information for the mineral ingredients used in Portland cement concrete in ODOT pavements and structures.
