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.

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 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.

MEPDG Analysis on Relationship between Design Inputs and Performance of Asphalt Pavements

Applied Mechanics and Materials, 2014
The main objective of this research is to explore the quantitative relationship between the pavement design parameters (structural layer thickness, voids, aggregate gradation and temperatures) and pavement performance parameters (rutting, cracking and IRI).

Performance evaluation of pavements with cement stabilized layer using MEPDG program and LTPP data

2021
The spring season causes melting of wintry ice in pavement structures. Therefore, transportation agencies use axle load limits to protect the pavement from deterioration during springtime. The use of cement treated base (CTB) in the pavement structure can provide a prospect to overcome this problem.

An experimental design-based evaluation of sensitivities of MEPDG prediction: investigating main and interaction effects

International Journal of Pavement Engineering, 2015
The mechanistic–empirical pavement design guide (MEPDG) uses mechanistic–empirical models by analysing the impacts of traffic, climate, materials and pavement structure to predict performances of pavement. The MEPDG software uses a three-level hierarchical input to predict performance in terms of terminal International Roughness Index, permanent ...

Predicting Subgrade Resilient Modulus for Use in the MEPDG Using Common Soil Indices

2018
In roadway pavement design, one must consider the performance of the pavement structure and mixture design. The tendency for pavement to be more flexible in nature gives increased importance to the properties and condition of the underlying soil subgrade.
