Jun 09, 2011  The resilient modulus can be expressed as 𝑀 𝑅 = 𝜎 𝜀 𝑟, ( 1) where 𝜎 is the applied stress and 𝜀 𝑟 is the recoverable axial strain. 𝑀 𝑅 describes the mechanical response of a pavement base or subgrade to the applied cyclic (traffic) load, and, hence it is considered to be an essential parameter for pavement design.
