With ever-increasing number of vehicles actively using the state and national roadway network, transportation-related fuel consumption and consequent pavement structural damage rises. In this dissertation, the impact of material-induced dissipated energy mechanisms in asphalt and concrete pavements were analyzed using field measurements in California and finite element modeling of pavement response. To investigate this phenomenon, full-scale moving load modeling scheme was developed to create numerical simulations representing field conditions. In particular, viscoelasticity in the asphalt layer and damping in the subgrade layer were represented as such mechanisms and the related dissipated energy values were converted to fuel metrics. In the end, developed moving load models were applied to another research study to investigate the delamination behavior and accumulation of bonding damage in
the tack coat layers (asphaltic emulsions applied between pavement lifts to provide adequate bond between the two surfaces). For each task, contributing field attributes were identified and evaluated and the most influential factors were reported.
