HIPERPAV (HIgh PERformance concrete PAVing) is a concrete paving software product sponsored by the FHWA intended to serve as a tool in the proper selection and control of the factors affecting concrete pavement behavior at early ages. This paper serves to describe two key components of the HIPERPAV system. The first is the core concrete temperature prediction model, which consists of a transient two-dimensional finite-element model. This model includes the effects of thermal conduction, convection, solar radiation, irradiation, and the heat of hydration of the cementitious materials. The second topic of this paper is the concrete strength development model, which is based on the equivalent age maturity concept. This model allows for an accurate prediction of the strength development in the concrete during the early-age period.
