LOW PERMEABILITY CONCRETE FOR BRIDGE DECK OVERLAY

A concrete mix design for bridge deck overlays with lower permeability to chlorides and low drying shrinkage may prove to be economically viable in spite of the high cost of some of the admixtures used. OBJECTIVE The objective of this project is to evaluate a variety of low permeability concrete mix designs which have the potential to

PPC 1121 Polyester Polymer Concrete Bridge Deck Overlays

When overlay materials offer low permeability, they often crack, giving moisture and chlorides a clear path to causing corrosion and freeze-thaw stresses at the bond line. KBP PPC 1121 has a low modulus of elasticity and high tensile strength which allows the material to resist cracking under the stresses of heavy traffic and normal bridge deck movements.
