FOREWORD

The High Performance Paving (HIPERPAV® ) III software program is a comprehensive yet user friendly software package. This software program will be of interest to those involved in concrete pavement mix designs as well as the design and construction of concrete pavements. In this user manual, guidance is given on how to use the new HIPERPAV® III software program for the analysis of early age Portland cement concrete pavement (PCCP) behavior.

Information on investigating, modeling, and validating the enhanced HIPERPAV® III is included in the report Computer Based Guidelines for Concrete Pavements: HIPERPAV III, Moisture Transport, and Sensitivity Analysis (Report No. PB2009 115483). The report is distributed through the National Technical Information Service (NTIS).

16. Abstract
This user manual provides guidance on how to use the new High PERformance PAVing (HIPERPAV®) III software program for the analysis of early age Portland cement concrete pavement (PCCP) behavior. HIPERPAV® III includes several improvements over previous versions including (1) improvements to the interface to allow users to navigate through the software program with more ease; (2) the ability to characterize heat evolution of a particular cement paste to improve the precision of the software program’s models; (3) the addition of a batch mode to allow users to analyze several strategies at once; and (4) the incorporation of a comparisons module with sensitivity analysis tools to offer users the opportunity to quickly discern differences in the effects of environmental, design, and construction variables on strength gain, stress development, and early age strength to stress relationships.

The objectives of this research project were to enhance the moisture transport modeling in the HIPERPAV® software program and to add features to further improve the software program. The moisture model study primarily covered the following content: (1) a literature review and evaluation of moisture transport models for concrete materials and pavements; (2) the development of a moisture transport model; (3) a mathematical solution for the moisture transport model using the one dimensional finite difference method; (4) the programming of the moisture transport model using FORTRAN® and VBA® coding; (5) a sensitivity analysis of the effects of model parameters, environmental and construction conditions on the moisture transport, and critical stresses and strengths; (6) the validation of the moisture transport model: and (7) the incorporation of the moisture transport model into the HIPERPAV® software program. The investigation, modeling, and validation of the enhanced HIPERPAV® III are included in the report Computer Based Guidelines for Concrete Pavements: HIPERPAV III, Moisture Transport, Sensitivity Analysis (Report No. PB2009 115483). The report is distributed through the National Technical Information Service (NTIS). Previously published HIPERPAV II reports are (1) Computer Based Guidelines for Concrete Pavements, Volume I: Project Summary (FHWA HRT 04 121); (2) Computer Based Guidelines for Concrete Pavements, Volume II: Design and Construction Guidelines and HIPERPAV II User’s Manual (FHWA HRT 04 122); and (3) Computer Based Guidelines for Concrete Pavements, Volume III: Technical Appendices (FHWA HRT 04 127).
