Simple AC/CRC Composite Pavement Design Using MEPDG
Journal of the Korean Society of Road Engineers, 2014PURPOSES : 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).

Probabilistic Numerical Simulation of Pavement Performance using MEPDG
Road Materials and Pavement Design, 2010ABSTRACT 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.

Application of MEPDG Dynamic Modulus Prediction Model in China
CICTP 2015, 2015In 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 ...

Effects of Subgrade Resilient Modulus and Climate Inputs on MEPDG
GeoCongress 2012, 2012Local 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.

Dynamic Modulus Master Curve Construction Using the Modified MEPDG Model
2013 1st International Conference on Artificial Intelligence, Modelling and Simulation, 2013Dynamic 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, 2012In 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, 2011Unlike 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.
