  • Abstract:
    This report describes the condition of the first high early strength latex modified concrete (LMC-HE) overlay to be constructed for the Virginia Department of Transportation. The overlay was prepared with type III cement and with more cement and less water than used in the conventional latex modified concrete (LMC) overlay. Tests of the bond and compressive strength of the LMC-HE overlay performed during the first 24 hours after installation .indicated that traffic could be placed on the overlay within 24 hours rather than the 4 to 7 days required for the conventional LMC overlay. Tests of the bond strength and permeability to chloride ion conducted after 1 year in service indicate that the overlay is performing satisfactorily. Pending continuing favorable test results, it is anticipated that LMC-HE overlays can be used in situations in which it is desirable to accelerate construction, to reduce inconvenience to motorists, to allow for installation during off-peak traffic periods such as weekends, to provide a more rapid cure in cold weather, to provide low permeability (compared to concrete without latex), and to provide high strength, particularly, high early strength.
