roads are continuously reconstructed or rehabilitated without any effort made to identify factor(s) responsible for their perpetual failure. Pavement failures can either be functi onal (surface pavement failure) or structural (deep-seated pavement failure). There are many factors that can influence the performance of highway pavement structure.
