Abstract:

This report describes a research effort directed toward finding a means for detecting delamination, one of the more serious forms of deterioration found in concrete bridge decks. It describes (a) one of the methods employed for delamination detection, (b) the development of the basic components required for automatic detection, and (c) the completed instrument resulting from the research. The detecting unit is in the form of a pushcart, roughly the size and shape of a power lawn mower. Also included in the report is an evaluation of the device accomplished by measuring specially constructed test slabs and numerous in-service bridges. The evaluation tests indicate that the instrument provides a practical and effective means for the routine detection of bridge deck delamination by maintenance personnel. The instrument was found to be insensitive to deck texture, or to thin asphaltic surfacing layers. The operation of the detector is not impaired by rolling speeds of up to about ten miles per hour.
