This section of the presentation shows a typical bridge deck overlay using silica-
fume concrete. The concrete mixture on this project contains a higher amount of
silica fume and is typical of mixtures used before combinations of fly ash and
silica fume were developed. This practice is still followed by many state
transportation agencies.
