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 ...

Application of MEPDG Dynamic Modulus Prediction Model in China

CICTP 2015, 2015
In order to research the dynamic modulus prediction of asphalt mixtures, one section of Lianxu Highway in Jiangsu Province, China was picked. The applied prediction equations are from the Mechanistic-Empirical Pavement Design Guide (MEPDG), and the prediction procedure could be broken into 3 steps: establishing the viscosity-temperature relationship ...

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 ...

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

Study of Load Spectra of the Jaozhou Bay Expressway Based on MEPDG

Applied Mechanics and Materials, 2011
To study the traffic characteristic and axles load spectra of Jaozhou bay expressway, WIM data was collected, axle configuration and vehicles classification was determined. The characteristic of truck traffic monthly distribution and the truck hourly distribution was studied and axle load spectra for major tuck class groups were developed.

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 ...

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.

Comparison of Idaho Pavement Design Procedure with AASHTO 1993 and MEPDG Methods

Transportation and Development Institute Congress 2011, 2011
Several in service pavements located in different regions of Idaho that have been designed according to the ITD design method were redesigned using the AASHTO 1993 as well as the Mechanistic-Empirical Pavement Design Guide (MEPDG) procedures. All designs were conducted at a 50% reliability level.

Evaluation of the MEPDG Dynamic Modulus Prediction Models for Asphalt Concrete Mixtures

Transportation and Development Institute Congress 2011, 2011
HMA dynamic modulus (E*) is one of key inputs to the Mechanistic-Empirical Pavement Design Guide (MEPDG). There are two different E* models in the MEPDG; the NCHRP 1-37A viscosity-based model, and the NCHRP 1-40D, which is based on the binder shear modulus. This paper focuses on evaluating the influence of the binder characterization input level on the
