HIPERPAV (High PERformance concrete PAVing) is a concrete paving software sponsored by the Federal Highway Administration (FHWA). It is intended to serve as a tool in the proper selection and control of the factors affecting concrete pavement behavior at early stages. This paper will discuss two key components of the HIPERPAV system. First, the paper will discuss the core concrete temperature prediction model, which consists of a transient two-dimensional finite-element model. The model includes the effects of thermal conduction, convection, solar radiation, irradiation, and the heat of hydration of the cementitious materials. The second topic discussed is the concrete strength development models, 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.
