Abstract

Abstract This paper discusses the resilient behaviour of various materials of high rigidity, high elasticity and of particulate materials. The resilient behaviour is measured by the resilient modulus (Mr) test which is the mechanical response of soils to a dynamic cyclic load which simulates traffic loading conditions and it is an important parameter in the design of both flexible and rigid pavements. The materials used are of a concrete cylinder, a rubber sample and particulate materials which are sands of different particle size and shape classification. The design resilient modulus follows a constitutive model and it is used to compare the resilient behaviour of each material. The constitutive model shows that the design resilient modulus is affected by the particulate characteristics and how it can be related to a stiff and flexible material.
