Validation of HIPERPAV for Prediction of Early-Age Jointed Concrete Pavement Behavior

Abstract

HIPERPAV is a computer program that was developed to predict the time growth of early-age portland cement concrete strength and stresses in jointed concrete pavements for the prediction of cracking. Each individual environmental, construction, design, and mix design input that influences early-age pavement behavior can be adjusted to find the optimum paving solution. A design that minimizes stresses and maximizes concrete strength will increase the potential for an extended service life. FHWA, aware of the benefits that HIPERPAV can provide in the field, provided funding for experimental validation. The results of this validation are presented. The experimental field instrumentation efforts are described and the analyses performed are discussed. The end result of validating HIPERPAV is increased confidence in the accurate prediction of early-age pavement behavior.
