Results showed that the milling-induced stress zone increases significantly with increased stiffness/aging. Viscoelastic and Drucker-Prager models with the maximum principal stress failure criterion and the erosion method were utilized to predict failure. The models were simulated at 25 ☌ and 60 ☌, with unaged, 60 months, and 120-month aged conditions. Using laboratory-measured stiffness, a three-dimensional finite element model (3-D FEM) was developed and validated with drop tower impact tests. The objective of this study was to predict the milling-induced stresses for two asphalt mixes. Milling is a necessary step for the removal of aged or distressed Hot Mix Asphalt (HMA) materials and recovery of Reclaimed Asphalt Pavement (RAP) for rehabilitation of asphalt pavements. The majority of the pavements in the world are surfaced with asphalt mixes.
