• Abstract:
  This report presents the construction procedures and initial performance evaluation of a four-inch Bonded Concrete Overlay placed on Interstate 80 near Moline, Illinois. Preconstruction testing consisted of Falling Weight Deflectometer, permeability to chloride, and distress surveys. Surface preparation included: full-depth patching, partial-depth patching, bituminous material removal, shot blasting, and sand blasting. During construction of the overlay, concrete temperature, air temperature; wind speed, relative humidity, rate of evaporation, concrete slump, concrete air content, water-cement ratio, placement time, and overlay thickness were recorded. Testing conducted after construction of the overlay included: compressive strength, split tensile strength, distress surveys, location of delamination, Falling Weight Deflectometer, California Profilograph, International Roughness Index, friction, drying shrinkage of concrete, and bond strength.
