INTERFACE BONDING OF THIN CONCRETE OVERLAYS DUE TO VEHICULAR VIBRATION. FINAL REPORT

This report presents the results from the third phase of a study dealing with the effects of vehicular vibrations on the interface bonding of thin concrete overlays on bridge decks. In this phase of the project, beams 90 cm long, 15 cm wide and 5 cm thick reinforced with 6.5-cm-diameter bars placed 5 cm apart were used. A 5-cm-thick or a 10-cm-thick overlay was placed on top of a base concrete. The specimens were tested by one-point line load flexural testing. The parameters investigated were surface condition, surface texture, pre-vibration cure time, overlay thickness, and vibration amplitude. These parameters were combined in different sequences to study their effects on the interface bonding of concrete overlays. Some recommendations are included so that the best bond strength can be obtained during construction.
