STUDY OF HIGHWAY DENSITY AND LATEX MODIFIED CONCRETE BRIDGE OVERLAYS

Portland cement concrete overlay surfacings for bridge decks which will effectively resist de-icing salt solution penetration are a major concern. The report compares the relative effectiveness of latex modified concrete and high density concrete overlays. This report is divided into the following chapters; (1) Introduction, (2) Compressive Strength and Air Content, (3) Density of Hardened Concrete, (4) Shear Bond Strength, (5) Chloride Penetration, (6) Roughness, (7) Skid Resistance, (8) Cracking, Delaminations, and Corrosion and (9) Conclusions. From the data it was concluded that the differences in the measurements between the two protective systems are minimal and that both latex modified concrete and high density concrete overlays provide adequate bridge deck protective systems.
