Abstract As a step-wise implementation effort of the Mechanistic-Empirical Pavement Design Guide (MEPDG) lor the design and analysis of Nebraska flexible pavement systems, this research develops 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 are 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, are evaluated to include Level 2 and/or Level 3 design inputs. Test results and layer modulus values are summarized in Appendices. Modulus values characterized for each design level are then input into the MEPDG software to investigate level-dependent performance sensitivity of typical asphalt pavements. The MEPDG performance simulation results then reveal 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.
