Abstract:

Inputs needed for mechanistic pavement design require complex, time-consuming tests not commonly conducted. As a result, pavements are designed using average or default material properties that might not represent the properties of materials actually used in construction. Doing so may result in inaccurate performance predictions and lessen the ability to optimize resources and conduct accurate life-cycle analyses. Tests for dynamic modulus (the elastic properties of various materials) at different temperatures and tests for cracking performance were conducted on nine different asphalt mixtures. The results were analyzed, and a relation was developed between the two different tests. Based on the analysis, the developed relation can predict the dynamic modulus master curve from IDEAL CT tests (tests to determine the cracking potential of asphalt mixtures). Comparisons between measured values and predicted values were made.
