PDF Using Styrene-Butadiene Latex in Concrete Overlays

The inclusion of latex in concrete reduces water demand of the mix, achieving a workable slump (4-6 in.) at a water­ cement ratio of 0.40 or less. This includes the water in the latex, typically 52 percent by weight. The primary criteria for LMC overlays are workability in the plastic state, bond and low permeability in the hardened state.

Corrosion Protection Measures

ACP overlay tends to trap salt laden moisture and thereby accelerate corrosion. Action. Limit the use of ACP overlay on new bridge decks whenever possible. If an ACP overlay must be placed on a deck, always specify a two-course surface treatment be applied first. The two-course surface treatment serves as a membrane to help protect the bridge deck.
