Project description

Portland cement concrete (PCC) pavements are subject to distress from a variety of mechanisms including traffic loads, thermal movement, freezing and thawing, materials related distress, and construction issues. Standard practice for maintaining PCC pavements includes concrete patching using partial depth and full depth repairs. States spend large amounts of money and time every year performing partial and full depth repairs of PCC pavements. The performance of partial and full depth repairs is important for cost savings and safety of the roadways.
