      The shear bond strength of the interface between the existing concrete and the new concrete was then measured according to the Arizona shear bond test method outlined in the Federal Highway Administration Report No. FHWA-RD entitled "Styrene Butadiene Latex Modifiers for Bridge Deck Overlay Concrete" Styrene butadiene rubber (SBR) became commonly used in bridge deck overlays after a study by the Dow Chemical Company and the Michigan Highway Department. The study found that SBR concrete had significantly lower chloride permeability than ordinary concrete. 2,3 Latex-modified concrete (LMC) is a sub-category of PMC, where latex is the polymer

Federal Highway Administration. Office of Research. Abstract. Mode of access: Internet One of the major uses of concrete modified with styrene-butadiene latex is for bonded overlays on bridge and parking garage decks.

The application has been in use for over 20 years, demonstrating the viability and long-term performance of this ://   • First utilisation of LMC by VDOT for a bridge deck overlay •London England: First conference International Conference on Polymers in Concrete [ [ • FHWA RD Report: Styrene-Butadiene Latex-Modifiers for Bridge Deck Overlays • Today– More t LMC overlays have been placed in Bridge deck overlay   • Low modulus of elasticity makes the concrete less brittle and more flexible for extended service life • Meets FHWA RD Requirements: Styrene-Butadiene Latex Modifiers for Bridge Deck Overlay Concrete.
