Dynamic Modulus Master Curve Construction Using the Modified MEPDG Model

2013 1st International Conference on Artificial Intelligence, Modelling and Simulation, 2013
Dynamic modulus, E is one of the fundamental properties defining the response of hot mix asphalt (HMA) mixtures in flexible pavement systems. Correspondingly, HMA materials are characterized by E master curve incorporating time and temperature effects. One of the widely used models, modified by Bonaquist (2009) is the MEPDG master curve model.

Investigation of Foamed Warm Mix Asphalt Performance Using the MEPDG

GeoCongress 2012, 2012
In recent years, warm mix asphalt (WMA) produced using foamed asphalt binder has gained popularity in the United States due to its ability to improve workability and compactability of asphalt mixtures produced at lower temperatures. As compared to other WMA technologies, foamed warm mix asphalt does not require the use of costly additives, making it ...

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.

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.

Lessons Learned from MEPDG Development: A Confession of the JPCP MEPDG Developers

Proceedings of the International Conference on Concrete Pavements
After 15 years from the initiation of the National Cooperative Highway Research Program (NCHRP) 1-37A project, the Mechanistic-Empirical Pavement Design Guide (MEPDG) developed under that study has been adopted by the American Association State Highway and Transportation Officials (AASHTO) and is in the process of adoption by many transportation ...

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

Systematic back-calculation protocol and prediction of resilient modulus for MEPDG

International Journal of Pavement Engineering, 2016
AbstractA research focusing on the characterisation of representative local material properties was conducted to facilitate the full implementation of the Mechanistic-Empirical Pavement Design Guide for roadway designs in Wyoming. As part of the test program, falling weight deflectometer deflection data were collected from 25 test sites in Wyoming for ...

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 ...

Sensitivity of Input Variables for Rigid Pavement Rehabilitation Strategies in the MEPDG

Airfield and Highway Pavement 2013, 2013
The Mechanistic-Empirical Pavement Design Guide (M-E PDG) can be used to design different flexible rehabilitation options; namely HMA over HMA (overlay), HMA over JPCP (composite), and HMA over JPCP fractured (rubblized). Each rehabilitation option has different input variables for new and existing layers. The type and magnitude of the input parameters
