A Review on Cracks and Patches on Road

Abstract

This paper presents a report of cracks and patches are same type of road surface distresses whose assessment is essential in India. At present, distress data collection is increasingly being automated by using various imaging system. This is expensive, time consuming and slows down the road maintenance management. A robust method of automated detection and assessment of cracks and patches from real life video clips of Indian highway is proposed. The local authority road networks commonly comprise roads of various functional characteristics and a variety of construction types. We are investigate about the use of digital technique to obtain field data to increase safety and reduce labour requirements using a semi automated distress collection and measurement system and also in the robust method cracks and patches are detected and quantified automatically using various image processing technique supported by heuristically derived decision logic. The algorithm automatically detects cracks and patches after the adjustment of the optical distortion. Moreover, the technique products an automatic classification and rating to create different categories. Patches have always been a problem for highway maintenance agencies because their repair is costly and time consuming.
