FOREWARD

This report documents the investigation and modeling of early-age behavior of both portland cement concrete pavements (PCCP) and bonded concrete overlays (BCO) subjected to stresses from moisture and temperature changes. A set of guidelines was developed which provide direction in the proper selection of design and construction variables to minimize early-age damage to PCCP and BCO. The guidelines first identify design and construction inputs that are most likely to lead to good behavior during the early-age period. They then take these inputs and incorporate them in a series of complex models developed to predict the behavior of jointed plain concrete pavement and bonded concrete overlays during this early period. The end product of this research is a comprehensive software package called  IPERPAV (for High PERformance PAVing). This report is Volume I of a three-volume set and is the Final Report of the study documenting the work carried out. Volume II is the User's Manual, which provides general instructions on the use and application of BIPERPAV. Volume III is the Addendum to the User's Manual, which provides specific guidelines for using the final version of the software and includes example screens in color.

This report will be of interest to those involved in concrete pavement mix design, as well as the design and construction of concrete pavements. Sufficient copies are being distributed to provide two copies to each FHWA Region and three copies to each FHWA Division and State highway agency. Direct distribution is being made to the FHWA Division Offices. Additional copies may be purchased from the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, Virginia 22161.
