Abstract:

This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures’ dynamic modulus master curves, based on NCHRP reports and other relevant literature, indicates that the dynamic modulus used as input to the AASHTOWare Pavement ME® software can be generated based on four parameters. Review of data from 34 different projects tested between 2007 and 2010 indicates that the asphalt mixtures used in Utah have consistent patterns that define the ranges of the parameters used to generate the dynamic modulus master curve. Furthermore, an analysis was conducted which confirmed that, theoretically, there should be some relation between the cracking tolerance index and the dynamic modulus. The relation was verified using asphalt mixtures from six different UDOT projects. Based on the literature review, the theoretical analysis, and the laboratory experiments, it was concluded that the feasibility of predicting portions of the dynamic modulus master curve using only the cracking tolerance index is reasonable. It is recommended that the results be verified using a different set of asphalt mixtures and that an actual predictive relation be developed.
