Abstract: The Road construction has become a growth engine for infrastructure development, across the country, consequently, we have experienced a tremendous growth in Infra-structure of India and National Highways specifically, the construction of pavement quality concrete highway has been the preferred option compared to the bituminous highway due to its low maintenance and long life. However, there are various types of cracks which PQC pavements develop post construction and during the service life. This paper describes the repairs of many types of cracks which are most common and develop either during construction, post construction and during the service life.The structural defects are highlighted in the form of various types of cracks in the slab. The settlement at joints may also occur and if the remedial action is not taken it may also lead to development of cracks.
