PAVEMENT DISTRESSES AND ROUGHNESS ODELING ? A CASE STUDY

Saranya Ullas, Sreelatha T, B.G Sreedevi

Pavement deterioration is very complex. It involves structural fatigue as well as functional distresses. It results from the interaction between traffic, climate, material and time. Deterioration is the term used to represent the change in pavement performance overtime. The ability of the road to satisfy the demands of traffic and environment over its design life is referred to as performance. Due to the great complexity of the road deterioration process, performance models are the best approximate predictors of expected conditions. In this study main distresses were identified from the selected road stretches. Regression models are then developed using SPSS (Statistical packages for social sciences) package.
