Abstract
The Resilient Modulus (MR) of a subgrade soil is an essential input into the flexible pavement design models contained in the American Association of State Highway and Transportation Official’s new pavement design guide, the MechanisticEmpirical Pavement Design Guide (MEPDG). For most inputs required for pavement design, there are three levels of input that can be used within the MEPDG system. Level One requires the engineer to enter a value for subgrade Resilient Modulus based on the results of Resilient Modulus tests conducted in the laboratory. Level Two allows the user to input values for other soil property tests including California Bearing Ratio (CBR), and resistance value (R-Value). The program then converts these numbers to Resilient Modulus values using empirical correlations. When a pavement designer does not have access to detailed data about the subgrade soil, Level Three inputs can be used. These inputs are educated guesses for the Resilient Modulus of the subgrade soil based on the AASHTO soil type entered.
