Calibration 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 کاملUse 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 کاملStudy of Iowa PCC Thermal Properties for Mechanistic-Empirical Pavement Design
The present research was designed to determine thermal properties, such as coefficient of thermal expansion (CTE) and thermal conductivity, of portland cement concrete (PCC) used in Iowa pavements. These properties are required as input values by the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG). In this research, a literature survey was conducted to determine the major factors tha...
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 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...
