EVALUATION OF CURING CONTINUOUSLY REINFORCED CONCRETE PAVEMENT

A field evaluation of curing continuously reinforced concrete pavement with white-pigmented liquid membrane and white translucent polyethylene (paper) curing agents was made on Wisc-15 in Walworth and Waukesha Counties, Wisconsin. Physical properties of the concrete were investigated, and it was concluded that the curing method does not significantly affect tensile or compressive strength of the modulus of elasticity. Data show that the temperature drop experienced by the concrete during the first 24 hours was not significantly affected by the curing agent. Strain readings on the reinforcing bars indicate that the steel stress was nearly equal in paper- and membrane-cured sections at a temperature of 64 F (18 C). Curing methods, as a 1 year of age, appear to be in the realm of transverse cracking, i.e., membrane curing allowed the pavement to crack earlier and to crack more at early ages. Both membrane and paper curing produced acceptable crack-spacing distributions when climatological conditions were favorable, although neither curing agent contributes to acceptable crack-spacing distributions during hot weather paving conditions. No cold weather paving was performed on this project.
