Concrete Pavement Overlays and Failure Mechanisms

摘要

This is the second technical report that describes a series of tasks performed under TxDOT Project 0-4893. The main objectives of this document are to present the findings of the assessment of various asphalt concrete overlay (ACO) projects built in the Bryan, Fort Worth, and Dallas districts. Likewise, it shows the results of the instrumentation of a bonded concrete overlay (BCO) section located in Houston, Texas, where debonding of the overlay was measured and discussed. Finally, the evaluation of a life cycle cost analysis (LCCA) program is evaluated and its use recommended in future overlay projects.
