The service life of latex-modified
concrete and low-slump dense concrete bridge deck
overlays is estimated by extrapolating historical
performance data obtained from the results of field
research and investigations conducted in the United
States and Canada. The data suggest that when concrete
removal criteria are based on half-cell potential
rather than actual damage, when removal of chloride
contaminated concrete is extended to below the rebar,
and when the substrate is sandblasted to remove
microcracking prior to cleaning, a mean service life of
30 to 50 years is likely.
