Early-age Behavior of Composite Pavements

There is a need for researchers to be able to model the early-age behavior of Portland cement concrete (PCC) pavements. To be useful to both researchers and practitioners, this model must describe the slab’s behavior by coupling models of dement hydration, creep effects, shrinkage and shrinkage cracking, sawcut timing/joint formation, and overall slab geometry (built-in curl). These researchers are developing a comprehensive tool to describe early-age behavior in PCC pavements that would account for early-age effects in pavement analysis and performance prediction by providing outputs to pavement design and by providing researchers with more sophisticated models for analysis.
