EVALUATION OF THIN LIFT POLYMER BRIDGE DECK OVERLAYS ON I-57 BRIDGES AT CLIFTON, IL
This construction report summarizes the placement of two thin lift polymer bridge deck overlays on adjacent structures carrying Interstate 57 near Clifton. Various tests were performed before overlay placement to determine the condition of the structures. Half-cell potential tests indicated that corrosion was underway in at least one-third of the southbound passing lane. Just before full-scale overlay placement, a test area was constructed using the proposed surface preparation and overlay placement methods. Pull-off tests (ACI 503R-80) indicated that the methods were sound, so construction proceeded. The overlay was placed during 4 days in September of 1995 using a broom-and-seed application method. A durable rhyolitic stone aggregate (trap rock) was used on both lifts. While the cost of thin polymer overlays is much greater compared to conventional overlays, the higher cost can be justified when a reduction in dead load is required. One potential benefit of thin polymer overlays, if proven successful, is in reducing lane closure times. This was not the case on this contract, since patches were cured for at least 28 days. However, recent contracts in Missouri have been completed with minimal curing periods. Future studies should include an evaluation of methods for expediting construction.
