  • Abstract:
    As a step-wise implementation effort of the Mechanistic-Empirical Pavement Design Guide (MEPDG) for the design ; and analysis of Nebraska flexible pavement systems, this research developed a database of layer moduli — dynamic ; modulus, creep compliance, and resilient modulus — of various pavement materials used in Nebraska. The database ; includes all three design input levels. Direct laboratory tests of the representative Nebraska pavement materials were ; conducted for Level 1 design inputs, and surrogate methods, such as the use of Witczak’s predictive equations and the ; use of default resilient moduli based on soil classification data, were evaluated to include Level 2 and/or Level 3 design ; inputs. Test results and layer modulus values are summarized in the appendices. Modulus values characterized for each ; design level were then put into the MEPDG software to investigate level-dependent performance sensitivity of typical ; asphalt pavements. The MEPDG performance simulation results then revealed any insights into the applicability of ; different modulus input levels for the design of typical Nebraska pavements. Significant results and findings are ; presented in this report.
