Optimal design of flexible pavements using a framework of DAKOTA and MEPDG

International Journal of Pavement Engineering, 2011
Pavement design optimisation is an active area of research. Due to a large number of parameters, such as thickness of layers, material properties, climatic conditions, affecting pavement performance, it is usually not feasible to determine an optimal design using a trial and error approach.

Comparison of AASHTO 1993 and MEPDG considering the Egyptian climatic conditions

Innovative Infrastructure Solutions, 2017
The current flexible pavement design system in Egypt was adopted primarily from the AASHTO 1993 Design Guide. It is an empirical design method based on the results of the late 1950s AASHO Road test with many limitations. Thus, the Mechanistic-Empirical Pavement Design Guide (MEPDG) which is now called Pavement ME Design was developed to overcome those ...

Study of MEPDG Sensitivity Using Nonparametric Regression Procedures

Journal of Computing in Civil Engineering, 2014
AbstractBecause the new Mechanistic-Empirical Pavement Design Guide (MEPDG) includes numerous inputs, a sensitivity analysis using the Monte Carlo approach is not practical because it requires thousands of MEPDG runs. Instead, nonparametric regression procedures can be very useful to perform MEPDG sensitivity analysis.

Validating MEPDG with Tennessee Pavement Performance Data

Journal of Transportation Engineering, 2013
To implement the Mechanistic-Empirical Pavement Design Guide (MEPDG) developed by AASHTO for pavement construction and rehabilitation, it is necessary to evaluate its performance prediction models using actual pavement performance data, material properties, traffic information, and environmental factors.

Evaluating Sensitivity of Pavement Performance to Mix Design Variable in MEPDG

Road Materials and New Innovations in Pavement Engineering, 2011
Unlike the AASHTO 1993 pavement design guide, the new Mechanistic Empirical Pavement Design Guide (MEPDG) is heavily dependent on asphalt mixture variables such as air void content, percentage binder, binder performance Grade (PG) at level 3 analyses.

Enhancing MEPDG distress models prediction for Saudi Arabia by local calibration

Road Materials and Pavement Design, 2021
During the development of pavement design methods, the MEPDG is evolved by NCHRP 1-37 project. This reason led the roadway agencies to implement the MEPDG.

Prediction of the Subgrade Resilient Modulus for the Implementation of the MEPDG in Idaho

Geo-Frontiers 2011, 2011
This paper focuses on developing two models for subgrade soil characterization for use in the Mechanistic-Empirical Pavement Design Guide (MEPDG). First, a multiple regression model can be used to predict R-value as a function of the soil plasticity index and percent passing No 200 sieve.

Effects of Subgrade Resilient Modulus and Climate Inputs on MEPDG

GeoCongress 2012, 2012
Local validation and calibration are essential steps before the local implementation of the newly developed Mechanistic-Empirical Pavement Design Guide (MEPDG). Recently, a comprehensive study was carried out in Louisiana to validate and calibrate the MEPDG models using the network-level pavement management performance data.

Evaluation of the MEPDG Permanent Deformation Models in Louisiana Conditions

GeoCongress 2012, 2012
The newly developed Mechanistic-Empirical Pavement Design Guide (MEPDG) utilizes a suite of nationally-calibrated, empirical damage models for different trafficinduced distresses commonly found in flexible pavements. To facilitate the MEPDG implementation in Louisiana, this study was aimed to address the local validation and calibration of the MEPDG ...

Simple AC/CRC Composite Pavement Design Using MEPDG

Journal of the Korean Society of Road Engineers, 2014
PURPOSES : Analysis and design of asphalt concrete (AC) and continuously reinforced concrete (CRC) composite pavements. METHODS : In this study, the service life of the AC/CRC composite pavements was determined based on the probabilistic method in the mechanistic-empirical pavement design guide(MEPDG).
