Optimizing Non-Linear Granular Layer Coefficients of a Flexible Pavement for Mechanistic-Empirical Method
نویسندگان
چکیده
In recent years, mechanistic-empirical (M-E) design methods are preferred in the of flexible pavements instead empirical using equations based on road performance tests. However, calibration transfer that convert mechanical responses to pavement life and definition layer materials used M-E have great importance for methods. this study, analyzes a cross-section designed with AASHTO-93 method were performed, service values calculated different equations. The obtained results compared method, compatible determined. Among examined, it was found rutting equation Asphalt Institute gave most consistent method. analysis selected cross-section, granular base sub-base layers defined as non-linear elastic reflecting actual in-situ conditions. K-Ɵ model definition, K1 K2 parameters optimized.

Empirical-Mechanistic Method Based Stochastic Modeling of Fatigue Damage to Predict Flexible Pavement Cracking for Transportation Infrastructure Management
In the purely theoretical approach of pavement design, percentage fatigue cracking is related to damage in a probabilistic manner according to the Miner’s law. Two methods that are currently widely in use are based on assumptions of damage distribution. One method assumes fatigue damage being normally distributed, while the other one assumes fatigue damage being lognormally distributed. Since m...
متن کاملA Methodology for Sustainable Mechanistic-Empirical Pavement Design
Roads cause significant impacts on the environment, such as contributing to emissions responsible for climate change. For this reason, pavement design methodology should integrate environmental as well as economical impacts. The objective of this study was to incorporate environmental impacts as part of the Mechanistic-Empirical (ME) pavement design procedure using Environmental Product Declara...
متن کاملCharacterization of Cementitiously Stabilized Subgrades for Mechanistic-empirical Pavement Design
Pavements are vulnerable to subgrade layer performance because it acts as a foundation. Due to significant increase in truck traffic, pavement engineers are challenged to build more strong and long-lasting pavements. To increase the load-bearing capacity of pavements, subgrade layer is often stabilized with cementitious additives. Thus, an overall characterization of cementitiously stabilized s...
