Abstract:

This report presents the results of a study conducted on the effects of vehicular vibration on the debonding and delamination of concrete overlays placed on structures. The thin-bonded concrete overlay is used by the Texas Department of Transportation on several projects. The concrete overlays are subjected to vibrations during their placement and cure. These vibrations are caused by the traffic on the adjacent lanes when a structure is constructed in phases. The parameters which were investigated are overlay thickness, cure time, vibration amplitude, vibration mode, surface texture, and surface wetness. These parameters were combined in different sequences and their effects on the shear strengths of the concrete overlays is reported. The shear strength results were compared based on surface wetness, overlay thickness, cure time and vibration mode.
