TRR: A Straightforward Procedure to Characterize Nonlinear Viscoelastic Response of Asphalt Concrete at High Temperatures

Rutting and fatigue damage are two major forms of distress that cause the most concern in asphalt concrete pavements, as they affect both serviceability and safety over the performance life of asphalt pavements. Rutting—permanent deformation under the wheels’ path—is more dominant at high temperatures, and fatigue damage—evolution of micro-cracks and micro-voids—generally is more problematic at low and intermediate temperatures.

"A Straightforward Procedure to Characterize Nonlinear Viscoelastic Response of Asphalt Concrete at High Temperatures," by Mohammad Bazzaz, Masoud Darabi, Dallas N. Little, and Navneet Garg, from 2018, was 2019's most cited article from Transportation Research Record.
