Computer-Based Guidelines for Concrete Pavements, Volume III: Technical Appendices
Primary Topic: Materials-Concrete
Description: This report documents enhancements incorporated in the (HIgh PERformance PAVing) HIPERPAV II software. Enhancements made within this project include the addition of two major modules: a module to predict the performance of JPCP as affected by early-age factors; and a module to predict the early-age behavior (first 72 hours) and early life (up to 1 year) of CRCP. Two additional FHWA studies were also incorporated: one that predicts dowel-bearing stresses as a function of environmental loading during the early age; and a module for optimization of concrete paving mixes as a function of 3-day strength, 28-day strength, and cost. Additional functionality to the software was also incorporated by reviewing and prioritizing the feedback provided by users of the first generation of the software, HIPERPAV I.
This volume includes the following technical appendices: A) annotated outline of the references investigated during this project; B) description of the models selected for incorporation in HIPERPAV II; C) field investigation of JPCP and CRCP sites used for model validation; D) validation of the enhanced HIPERPAV II computer guidelines; and E) finite-difference temperature model validation. This is the third volume and last in a series of three volumes that document the different tasks carried out in accomplishing the objectives for this project.
