Comparing Layer Types for the Use of MEPDG for FDR Design
… by the Mechanistic Empirical Design Guide (MEPDG). Current practice is to treat FDR as an unbound granular base layer, but this does not account for the added stability of the selected stabilization technique. However, previous research has shown that FDR may be more accurately characterized …

Adjustment factors for MEPDG pavement responses considering three- dimensional analysis and wide-base tire
The Mechanistic-Empirical Pavement Design Guide (MEPDG) provides a superior methodology as compared to its predecessor in the design and analysis of pavement structures. The mechanistic (MEDPG analysis) calculates critical pavement responses due to pavement-tire interactions. On the other hand, the …

Mechanistic-Empirical Pavement Design Guide (MEPDG) Method Implemented to Estimate Damage in Flexible and Rigid Pavements
… the Empirical-Mechanistic Pavement Design Guide (MEPDG) method for flexible and rigid pavements requires numerous input parameters. Most of these parameters can be easily determined while some require best estimates that are usually extracted from available literature. This thesis identifies the …

Risk Analysis and Reliability Improvement of Mechanistic-Empirical Pavement Design
… the Mechanistic Empirical Pavement Design Guide (MEPDG) is a congregated indicator defined as the probability that each of the key distress types and smoothness will be less than a selected critical level over the design period. For such a complex system as the MEPDG which does not have …

Evaluation and modeling of repeated load test data of asphalt concrete for mechanistic-empirical flexible pavement design
… Mechanistic-Empirical Pavement Design Guide (MEPDG) uses a power model that incorporates Dynamic Modulus (DM) as a factor in predicting rutting performance of asphalt concrete. The rutting model is empirical and the rutting profiles obtained from the model are largely based on the adjustment …

Characterization of Ohio Traffic Data for Integration into the Mechanistic-Empirical Pavement Design
The MEPDG requires a multitude of traffic inputs to be defined for the design of pavement structures. These inputs include (a) base-year traffic data such as the initial two-way annual average daily truck traffic (AADTT), (b) traffic volume adjustment factors (directional and lane distribution …

Validating the empirical distress prediction models within the AASHTOWare Pavement Mechanistic-Empirical Design, using Tennessee pavement performance data from the Long Term Pavement Performance database
The Mechanistic-Empirical Pavement Design Guide (MEPDG) represents a recent pavement design approach, developed to address the shortcomings of the 1993 AASHTO Guide for Design of Pavement Structures. The Pavement Mechanistic-Empirical Design (PMED) software is set to operationalize the …

Evaluation of In-Situ variability of concrete pavement characteristics and their effect on performance
… The Mechanistic Empirical Pavement Design Guide (MEPDG) is a tool used to evaluate the performance of JPCP, which predicts pavement distresses based on a desired reliability of design. MEPDG's current reliability analysis does not allow the MEPDG to quantify the effect of improved material …

Cement Stabilized Crushed Stone Base Course Strength and Stiffness Analysis
… the Mechanistic-Empirical Pavement Design Guide (MEPDG), referred to as AASHTOWare Pavement ME [2]. The 1993 AASHTO flexible guide applies empirically derived unitless strength values referred to as structural layer coefficients and structural numbers (SN) to pavement thickness and pavement types. …
