Project Description:	HIPERPAV© (HIgh PERformance Concrete PAVing) software was first released in 1996, followed by an updated version in 2005. The software program allows users to predict early-age concrete pavement behavior based on user-defined inputs for environmental, design, and construction conditions. The user inputs variables such as ambient weather conditions, thickness of pavement, mix design, time of placement, and type of curing. Mathematical models then calculate the progression of the concrete’s strength gain and developing stresses for the first 72 hours after placement. In the new HIPERPAV III©, an enhanced moisture transport model has been developed, incorporated into the software, and has been released in January 2010. The improved moisture model captures the interaction between pavement design, materials, environmental, and construction inputs and provides a more realistic characterization of moisture transport in the slab and its effect on early-age drying shrinkage, warping stresses, and strength development in the slab. The Transtec Group, Inc., under a Federal Highway Administration (FHWA) contract, is currently working on further enhancing the HIPERPAV III© software program to incorporate additional features. These features will include automatically downloading weather data from the National Weather Service Web site and adding slag aggregate input into HIPERPAV III©, along with its default thermal properties, such as coefficient of thermal expansion, specific heat, and thermal conductivities.
