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. This paper in 40 km length of NH-27 was selected, starting from Kota to Anta, to
carry out survey of pavement distress. 200 m intervals 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, cracks, patch
and rutting. All the distresses found have values exceeding maximum limits. The most required probable treatments
for surveyed distresses are overlay, patching. It was also observed that the side drainages were not maintained,
cleaned and even absent in some places of the NH-27
