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 jointed plain concrete pavement (JPCP) as affected by earlyage factors, and a module to predict the early-age behavior (first 72 hours) and early life (up to 1 year) of continuously reinforced concrete pavement (CRCP). Two additional Federal Highway Administration (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. |
