Many Interstate and other major highways that were constructed with jointed portland cement concrete pavements have reached their design life and consequently are deteriorating significantly. Few transportation agencies have an effective method for evaluating the structural adequacy of transverse joints. Most pavement rehabilitation programs now under way are based on subjective engineering judgment. A more objective evaluation procedure is presented. A newly developed finite element program, JSLAB, was used in a parametric study to determine which variables have the most significant effect on the performance of transverse joints. It was concluded that the variables that most significantly affect pavement deflections and stresses are the modulus of subgrade reaction and the modulus of dowel-concrete interaction. On the basis of this study, it was concluded that a rigid pavement system can be structurally evaluated if the modulus of subgrade reaction and the dowel-concrete modulus are known. Charts were developed to determine these moduli and subsequently to evaluate in-service pavements.
