HIPERPAV Software

Validation Model Summary | HIPERPAV Technical Memorandums | HIPERPAV FAQ's

Meet the new and improved HIPERPAV® III software program. First developed by the Federal Highway Administration (FHWA) in 1996 and then updated with the release of the HIPERPAV® II version in 2005, the free High PERformance Concrete PAVing (HIPERPAV®  software is a simulation tool for determining the early age behavior of portland cement concrete (PCC) pavement (during the first 3 days after construction).  As the HIPERPAV software has evolved, it has become complex and sophisticated but maintained its ease of use and user friendliness.

HIPERPAV® III features enhancements aimed at making the software even more effective and user friendly. The new HIPERPAV® III version features significant improvements, including enhanced temperature predictions for the heat of hydration and an enhanced moisture model. With the new moisture modeling features, users can more realistically compare the effect of various curing strategies and environmental conditions, resulting in improved predictions of critical stresses, material strengths, and drying shrinkage. This has greatly enhanced the software’s ability to predict the potential for early-age portland cement concrete pavement cracking.

Also newly added are a batch mode that allows the user to analyze several strategies at once, a Quick Compare tool that can be used to view the differences between up to four strategies simultaneously, and a sensitivity comparisons tool. The comparisons tool offers the user an opportunity to quickly discern differences in the effects of environmental, design, materials, and construction variables on strength gain, stress development, and cracking risk.

Looking ahead, potential future HIPERPAV® enhancements include the ability to enter the project Zip Code or geographic coordinates and download local weather data via the Internet, as well as the use of wireless technology to obtain data on site-specific climatic conditions and pavement surface temperatures.
