This paper summarizes the ongoing researches about the defects in flexible pavement and the maintenance in flexible pavements. In the past, lots of researchers have already studied the defects and problems of maintaining the flexible pavements all over the world. Efforts have been made to refer some of the publications related to this topic. Various defects in flexible pavements have been identified since the existence of flexible pavement. Pavement structure can be destroyed in a single season due to water penetration. Defects in flexible pavements is a problem of multiple dimensions, normal growth of vehicular traffic (in terms of no. of axle loading of commercial vehicles), the rapid expansion in the road network, non-availability of suitable technology, material, equipment, skilled labour and poor funds allocation have all added complexities to the problem flexible pavements. Maintenance is set of activities directed towards keeping a structure in a serviceable state during its design life. Maintenance of a road network involves a variety of operations, i.e., identification of deficiencies and planning, programming and scheduling for actual implementation in the field and monitoring. The essential objective should be to keep the road surface and appurtenances in good condition and to extend the life of the road assets to its design life. Broadly, the activities include identification of defects and the possible cause there off, determination of appropriate remedial measures; implement these in the field and monitoring of the results.
