Base Course Resilient Modulus for the Mechanistic-Empirical Pavement Design Guide, Summary Report
Elastic modulus determination is often used in designing pavements and evaluating pavement performance. The Mechanistic-Empirical Pavement Design Guide (MEPDG) has become an important source of guidance for pavement design and rehabilitation. MEPDG recommends use of modulus over structural number for pavement base layer thickness design. For the MEPDG Level-2 and Level-3 material parameter inputs, modulus is input as a single linearly elastic parameter. However, modulus is nonlinear with respect to several critical factors, such as effective confinement stress, loading strain, and moisture. These nonlinear dependencies must be properly understood for the accurate and effective application of modulus in pavement design. However, MEPDG does not offer a standard procedure for determining this single elastic modulus value.
