Evaluation of Ability of HIPERPAV to Predict Climatic Conditions and Sensitivity of HIPERPAV to Climatic and Support Conditions

This article describes software that was developed for the Federal Highway Administration (FHWA) to provide industry with a user friendly means for predicting the behavior of early-age concrete pavements. This report analyzed the most recent version of the software. The focus was on determining the ability of the software to correctly predict the climatic conditions that are present during the first 72 hours after paving. The sensitivity the strength and stress development predictions by the software to the climatic inputs was also evaluated. Finally the sensitivity of the software to various support conditions was characterized. The software was used to evaluate S.R. 22 in Murrysville, Pennsylvania. This road is heavily instrumented with climatic sensors. It also has a weather station onsite. The software was found to predict both temperature and humidity reasonably well. However, it was not able to predict wind speed or cloud as well. Methods for characterizing the support layers were also evaluated. Little documentation was found on defining the inputs for the nonlinear friction model. The support conditions did not significantly affect the stress development within the slab for the wide range conditions considered.
