Publication Type:
Technical Note
Publication Number:
FHWA-HRT-22-087
Abstract:

The primary objective of this document is to explore a series of techniques to inhibit the corrosion of existing reinforcement in conventional concrete bridge decks prior to installing an overlay, with an emphasis on UHPC overlays. The secondary objective is to assess the bond strength between the overlay and the concrete substrate in the presence of these different corrosion-inhibiting techniques.

Key Words—Overlay, bridge deck, corrosion, inhibitors, bond, UHPC.
