Probabilistic Numerical Simulation of Pavement Performance using MEPDG

Road Materials and Pavement Design, 2010
ABSTRACT It is widely acknowledged that the accurate simulation of complex engineering systems, such as nuclear power reactors, modern weapon systems, and aircraft, requires probabilistic analysis due to inherent uncertainties in their models' parameters.

Evaluation of MEPDG flexible pavement design using pavement management system data: Louisiana experience

International Journal of Pavement Engineering, 2013
This paper presents a recent study on using the mechanistic–empirical pavement design guide (MEPDG) design software (version 1.1) to evaluate the performance of typical Louisiana flexible pavement structures and compared it to the existing pavement performance data available in the pavement management system.

Local Calibration of MEPDG for Flexible Pavements in New Mexico

Journal of Transportation Engineering, 2013
AbstractLocal calibration of the mechanistic-empirical pavement design guide (MEPDG) is performed by determining the pavement-performance model coefficients to minimize the difference between the measured and predicted distresses of New Mexico department of transportation (NMDOT) pavements. A total of 24 New Mexico pavement sections, which have all the

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.

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).
