Urban Interstate Portland Cement Concrete Rehabilitation Alternatives for Washington State


Two urban Interstate portland cement concrete (PCC) pavements (SR 5 in Seattle and SR 90 in Spokane) were studied in order to (1) determine the mechanisms causing their deterioration, (2) estimate when the pavement condition would become unacceptable and the best time for rehabilitation, and (3) determine suitable rehabilitation alternatives. The rehabilitation alternatives were examined on a life-cycle cost basis.

The research done in this study was a combination of efforts at the University of Washington through the Washington State Transportation Center (TRAC), University of Illinois, and the Washington State Department of Transportation.
