Effect of the Field-Stress State on the Subgrade Resilient Modulus for Pavement Rutting and IRI
Geotechnics, 2023 The new Mechanistic-Empirical Pavement Design Guide (MEPDG) uses the subgrade resilient modulus (MR) as the key input parameter to represent the subgrade soil behavior for pavement design.

Influence of Unbound Materials Input Level on Pavement Performance using MEPDG [PDF]
Bulletin of the Faculty of Engineering. Mansoura University, 2020 For material characterization, the new Mechanistic Empirical Pavement Design Guide (MEPDG) has 3 input levels. Level 1 input values must be obtained through direct laboratory testing. Level 2 inputs are determined by the application of correlations with other material properties. Finally, Level 3 inputs are simply typical default values.

A Review on the Resilient Response of Unsaturated Subgrade Soils
Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Considering the great contribution of subgrade modulus to the overall performance of roads or railways, it is crucial to provide the best prediction of resilient modulus for their foundations. Incorporating the seasonal variation of moisture content, the resilient modulus variation of unsaturated soils will be accurately predicted.

Journal of Advanced Transportation, Volume 2020, Issue 1, 2020., 2020 Pavement performance prediction is a crucial issue in big data maintenance. This paper develops a hybrid grey relation analysis (GRA) and support vector machine regression (SVR) technique to predict pavement performance. The prediction model can solve the shortcomings of the traditional model including a single consideration factor, a short prediction ...
