Case Study of Overlay Performance of Continuously Reinforced Concrete Pavement (CRCP) Located on IH-35, Bowie County, Texas
The report documents a case study of an overlaid Portland Concrete Cement (PCC) pavement on IH-30, Bowie County, Texas. The 16-km (10-mile) project, constructed in April 1972, was first rehabilitated with an asphalt concrete pavement (ACP) overlay in May of 1986. Condition surveys of the project have been taken continuously at varying intervals, from the point of construction to the present. In June 1993, the project was again scheduled to be rotomilled and overlaid with 5 cm (2 inches) of ACP overlay. This rehabilitation effort created a unique opportunity for studying overlay performance. Condition survey, deflection, and profile data were all collected on the project before rotomilling (on the old overlay), after overlay (on the exposed PCC), and after the new overlay has been placed. Three analyses were performed: First, the failure history of the pavement was evaluated; second, a spectral analysis of the pavement profile was performed to determine the roughness reduction benefit of the overlay; and, finally, back-calculations of the concrete, subbase, and subgrade moduli were obtained to determine the development of fatigue in the pavement and the extent to which it was mitigated by the ACP overlay. Taken together, the study shows that, while a thin overlay restores ride quality, reduces the rate of failure development and minimizes dynamic loading, the overlay does little to reinforce or reverse the development of fatigue in the underlying layers.
