ABSTRACT
ABSTRACT: Pavement rutting is caused by the accumulation of residual deformation in one or more of the pavement layers and in the subgrade. The application of repetitive wheel loads result in certain amount of residual and permanent strain in the pavement layers. With the passage of traffic this residual/permanent strain will accumulate and ultimately lead to significant failure by rutting. The rutting in the underlying layers will also contribute to the rutting characteristics of the layers above. Hence it is essential to use appropriate constitutive models for pavement materials and solution techniques which will capture these responses to simulate the actual behavior of pavement under traffic loading.
