Abstract: Potholes are one of the most visible and annoying forms of bituminous pavement deterioration from the point of view of a road user. Potholes have always been a problem for highway maintenance agencies as their treatment is complex, costly and time-consuming. Materials for expedient roadway pavement repairs must provide a trafficable repair in the local condition in a minimal amount of time. Therefore, any repair material must be able to cure quickly and be easier to use. A large number of branded rapid repair materials mixes based on emulsion or cutback bitumen are available for pavements. Repairs with these materials can generally be opened to traffic almost immediately after placement, with some displacement, depending upon the loads. These products will gain more stability with time. Repair materials using cut-back asphalts generally provide a good combination of workability and long-term storage under adverse conditions. In the present study one such type cut back bitumen based pothole repair mix has been evaluated based on workability, strength using Marshall Stability and indirect tensile strength, and durability in regards to cohesion and adhesion properties. Along with the laboratory evaluation, the material is used in field for repair of pothole. This research paper deals with laboratory and field evaluation of the pothole repair method and certain details of performance.
