Pavement Distress: A Case Study


Pavement design, the process of developing the most economical combination of pavement layers, mainly deals with the design of material mixtures and thickness of different pavement layers. Even if highway pavements are well designed and constructed, they may require proper maintenance; and if not, different distresses like fatigue cracking, bleeding, rutting, potholes etc occur in the pavement which is considered to be complex phenomenon because of several factors involved (like rainfall, traffic etc.). 20 km length of NH-52A was selected, starting from Nirjuli to Itanagar, to carry out survey of pavement distress. 50 important locations of 400 m interval in the highway were selected for the study. In this study, the observation showed that the most commonly found pavement distresses in the highway were pot holes, alligator cracks followed by raveling and edge failure. All the distresses found have values exceeding maximum limits. The most required probable treatments for surveyed distresses are overlay, patching and shoulder improvement. It was also observed that the side drainages were not maintained, cleaned and even absent in some places of the NH- 52A.
