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

2. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide
Abstract : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. READ MORE

3. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements
Abstract : Mechanistic-Empirical (M-E) pavement design procedures are composed of a reliable response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic theory (MLET) with improved computational performance by optimizing the time consuming parts of the MLET processes.

4. Investigation of the structural response of pavements in cold region using instrumented test site data
Abstract : The structural behaviour of pavement structures is known to be affected by the traffic-related loading and by the ambient factors to which the structure is subjected. A new mechanistic-empirical (M-E) pavement design method is under development in Sweden with the main purpose to adequately predict pavement structural response and performance. READ MORE

5. Reliability-based Design Procedure for Flexible Pavements
Abstract : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This failure mode has been observed in many parts of the world, and in some regions, it was found to be more prevalent and a primary cause of pavements failure. READ MORE
