Durability is not an intrinsic property of the concrete, butinstead is related to how the material interacts with the environment. Durability-related deterioration is referred to asmaterials-related distress (MRD). Common MRDs include those caused by physical processes, such as freezing andthawing, or chemical processes, such as alkali-silica reactivity (ASR) and sulfate attack. This research project wasundertaken to determine whether concrete used in the ADOT system is experiencing, or is potentially susceptible to, ASR orsulfate attack, and if so, to what degree
