An evaluation of cores sampled from six concrete pavements was performed. Factors contributing to pavement distress observed in the field were determined, including expansive alkali-silica reactivity and freeze-thaw deterioration related to poor entrained air-void parameters. A laboratory study to investigate the role of alkali-silica reactivity through accelerated mortar bar and concrete prism testing was proposed.
