In order to assess the effect of curing practices on the set of new constructed concrete pavement, a field investigation was undertaken at the Florida Department of Transportation (FDOT) State Materials Office (SMO) in Gainesville, Florida. This study investigated early age concrete pavement behavior with respect to the development of the set gradient. In this study, four test slabs were placed and cured under different conditions to create different states of stress and creep behavior during and after hardening of the concrete. Early age concrete temperature and moisture history are key factors affecting the slab curling and warping behavior as well as the set gradient that resulted in the test slabs. These factors are of course affected by variations of ambient weather, the curing compound type, and application rate which in turn were found to be important with respect to the induced temperature and moisture gradients inside the slab. The paper elaborates the details of the analysis of the test data associated with the development of the set gradient.

This paper was sponsored by TRB committee AFD50 Standing Committee on Design and Rehabilitation of Concrete Pavements.
