A pavement may be considered to have failed when the deformations of its components are sufficiently large to cause an intolerably uneven riding surface or to cause cracking of the surfacing material. It has been recognized for many years that either or both of these modes of failure will develop if there is excessive plastic deformation of the pavement compounds and methods of pavement design have been developed to minimize the possibility of failure due to this cause. The aim of the paper is to throw light on the resilience characteristics of clay subgrades with respect to their influence in causing fatigue failures in asphalt pavements.
