Project ObjectivesProject Objectives

Evaluate E* for Mixes that are commonly used in Idaho.

Determine E* vs. Temp for various binders used in Idaho, especially for polymer modified asphalts.

Develop constitutive models and develop procedure to estimate E* from given mix design properties.

Study of Gyratory Stability (GS) in relation to E*. Develop and evaluate mix fracture indicators for

ITD mixes. Incorporate reliability analysis.
