Bonded concrete overlays could provide cost-effective rehabilitation methods for structurally deficient Portland cement concrete (PCC) pavements. Four-inch bonded concrete overlay (BCO) placed in 1986 on Houstons IH 610 North has provided quite satisfactory performance for more than 20 years. Ten test sections were placed as a part of the BCO project during the construction, and after 20 years, they provide invaluable information on the long-term performance of BCO. The variables included in the test sections are reinforcement, coarse aggregate type, and existing pavement condition. The overall performance of 4-in. BCO has been excellent, even though there were a few patches made to address partial depth punchouts. Four-inch BCO over 8-in. continuously reinforced concrete pavement (CRCP) reduced deflections by about one-third, which is good evidence for BCOs ability to enhance the structural capacity of under-designed PCC pavements. Between the two reinforcement types used, welded wire fabric and steel fibers, welded wire fabric provided better performance.
