• Abstract:
  An investigation of the delamination of thin-bonded concrete overlays was conducted on 6 overpasses on IH-10 in El Paso, Texas. These 200-ft overpasses consist of 3 spans of Precast Concrete Box Beams with a wood float finish. The 30-inch diameter columns rest on 36-in. diameter drilled shafts. The overpasses were constructed in two phases with the thin-bonded overlays (average 3 112-inch depth) being poured in the summer of '87 (phase I; outside lanes) and in the spring of '88 (phase II; inside lanes).
