Modelling Flow Rutting in In-Service Asphalt Pavements using the Mechanistic-Empirical Pavement Design Guide

Abstract
Permanent deformation is a serious distress mechanism in asphalt pavements. Modelling is a tool for performance prediction and deterioration assessment. This study evaluated the Mechanistic-Empirical Pavement Design Guide (M-E PDG) model for permanent deformation in asphalt concrete by employing the v1.003 software at level 1 and 3 on two Swedish motorway sections. Dynamic modulus data was obtained using the indirect tensile test on field cores. Level 1 and 3 results differed heavily due to over-predicted dynamic modulus data at level 3. However, the M-E PDG national field calibration is currently limited to that level. Therefore, level 3 appears to be the only usable level until the predictive dynamic modulus equation and the permanent... (More)

However, the M-E PDG national field calibration is currently limited to that level. Therefore, level 3 appears to be the only usable level until the predictive dynamic modulus equation and the permanent deformation model have been further calibrated. Previously found regional field calibration factors derived with accelerated loading tests improved model accuracy, although national calibration was sufficient. (Less)
