In India, 37 kms of national highways are being newly constructed every day and in the last seven years itself, the length of national highways have almost doubled in the country. The road pavement condition plays a crucial role on safety, comfort, traffic, travel times, vehicle operating cost and emission levels. In the present study, an extensive literature survey was carried out on the functional evaluation of pavements which usually involves the three components, namely, the distresses such as cracks, potholes, surface roughness, and skid resistance. It was found that in developed countries like USA, Europe, and China, the visual condition survey is gradually being replaced by use of advanced technologies like Light detection and ranging (LIDAR), where the accurate three-dimensional (3D) model of the road surface was created and using which, mapping of common surface distresses was done, which will eliminate any subjectivity of the evaluator. Though smartphones were used for functional evaluation of pavements in India, however studies using LIDAR could not be found. This necessitates the need for such studies in India, where the manual evaluation is a labor-intensive and time-consuming task considering the length of roads in the country. In addition to the review of literature, a pilot study was also carried out in Vellore, India using a 3D laser scanner in order to explore its usefulness in pavement distress evaluation. A point cloud of 8.23 million data points with X, Y, and Z values was collected and using which the pothole characteristics were calculated. It was found that the LIDAR derived point cloud data has very high potential in mapping the pothole and other distresses as it can record the minute height differences of even 1 mm.
