Literature Search 605: Bridge Low Slump Concrete Overlay ...

The low-slump overlay has effectively protected the reinforcing steel in the deck from chloride infiltration away from cracks, and service life analysis suggests that the service life extension provided by the highly impermeable low-slump concrete may be as high as 80 years when compared to typical bridge deck concrete alone. Repairs for this ...

Chloride Permeabilities of Rigid Concrete Bridge Deck

A study of the chloride permeability of rigid concrete bridge deck overlays was conducted during the 1987 construction season. A total of thirteen latex-modified concrete (LMC) overlays, ten superplasticized dense concrete (SDC) overlays, and two con­ densed silica fume concrete (CSFC) overlays, were investigated.

Use of Ultra-High-Performance Concrete for Bridge Deck ...

Mar 31, 2018  A potential solution, suggested in a previous study, is to apply a thin layer of ultra-high-performance concrete (UHPC) on top of normal concrete (NC) bridge decks. Because UHPC has a higher tensile strength and low permeability, cracking as well as water and chloride ingression can be minimized, which in turn will extend the lifespan of the ...
