ABSTRACT
The availability of several analysis tools and utilized models for Asphalt Concrete (AC) material characterization implies that the calculated pavement responses are non-unique. Potential variations are expected to have an impact on the bearing capacity assessment and the pavement life expectancy estimation. In the present research study, the investigation considers two powerful and worldwide used viscoelastic analysis tools, namely the 3D-Move and the ViscoRoute. Although both programs are similar, there are differences in the formulation and the way the input information is provided in the format required. This study emphasizes on the produced output (in particular the calculated tensile strains at the AC bottom, related to AC fatigue performance) and its potential impact on pavement engineering and decision-making issues, considering locally utilized AC materials.
