Abstract: The aim of this paper is to prove that CBR repeated test is useful to give an adequate like Unconfined Cyclic Triaxial test parameters for design the pavement and subgrade soils. That parameters are the Modulus of Elasticity also called Young’s modulus and the Resilient modulus (Mr) which is the elastic modulus based on the recoverable strain under repeated load. Modulus of elasticity (E) can be determined for any solid material and represents the ratio of stress and strain (stiffness). Resilient modulus (Mr), is an important parameter which characterizes the subgrade’s ability to withstand repetitive stresses under traffic loadings. The 1986 AASHTO guide for design of flexible pavements recommends the use of Mr. In that paper both parameters E and Mr of the subgrade clayey soil by laboratory CBR repeated test were determined using for calculation formulas from triaxial cyclic test.
