  2. 1. Mechanistic-Empirical Modeling of Permanent Deformation in Asphalt Concrete Layers

    Author : Erik Oscarsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; modeling; Mechanistic-Empirical; rutting; asphalt concrete; full-scale pavements;

    Abstract : Three mechanistic-empirical permanent deformation models were evaluated under Swedish conditions with respect to traffic, climate and materials using accelerated pavement testing and long-term pavement performance studies. The mechanistic-empirical pavement design guide (M E PDG), the incremental-recursive mechanistic-empirical CalME model (CalME), and the PErmanent Deformation of asphalt concrete layer for ROads (PEDRO) model generally showed both useful features and limitations.
