Development of Dynamic Modulus Parameters from Single Point Tests

This research seeks to develop a relation between quality-control/quality-acceptance material tests that have been developed to control cracking (bending beam rheometer for mixtures at low temperatures, and the IDEAL CT at intermediate temperatures) and the dynamic modulus, E*, master curve. The master curve values are used as input to the pavement design software but, due to difficulty in determining the dynamic modulus, national averages are often used rather than specific local material properties. This work will result in a relation between the material properties and the structural design of pavements which will allow for cost optimization and improvement of pavement mixes to minimize cracking (a major maintenance issue).
