DEBONDING OF HIGHWAY BRIDGE DECK OVERLAYS

This article uses field experience from Alberta, Canada, as the basis for a discussion of concrete-to-concrete debonding mechanisms, contributing factors to debonding, and expected overlay service life of highway bridge decks. Debonding of concrete bridge deck overlays at the interface between the overlay and substrate deck is a primary cause of eventual overlay failure, yet relatively little information about debonding over time is available in the technical literature. Alberta field experience indicated that overlay bond service life depends on some general factors, such as placement quality, substrate soundness, and substrate stability. Good overlays in Alberta can be expected to provide more than 30 years of service life, while poor overlays may require repairs within 5 years of placement.
