Use of Pavement Management Information System for Verification of Mechanistic-Empirical Pavement Design Guide Performance Predictions
The performance models used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) are nationally calibrated with design inputs and performance data obtained primarily from the national Long-Term Pavement Performance database. It is necessary to verify and calibrate MEPDG performance models for local highway agencies' implementation by taking into account local materials, traffic informatio...
متن کاملCalibration of Pavement ME Design and Mechanistic-Empirical Pavement Design Guide Performance Prediction Models for Iowa Pavement Systems
The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance models and the associated AASHTOWare® Pavement ME Design software are nationally calibrated using design inputs and distress data largely from the national Long-Term Pavement Performance (LTPP). Further calibration and validation studies are necessary for local highway agencies’ implementation by taking into acc...
متن کاملSensitivity analysis of rigid pavement systems using the mechanistic-empirical design guide software
Initiatives are underway to implement the new Mechanistic-Empirical Pavement Design Guide (MEPDG) in Iowa. This paper focuses on the sensitivity study of Jointed Plain Concrete Pavements (JPCP) and Continuously Reinforced Concrete Pavements (CRCP) in Iowa using the MEPDG software. In this comprehensive study, the effect of MEPDG input parameters on the rigid pavement performance is evaluated us...
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...
