This synthesis report will be of interest to department of transportation, county, and municipal engineers, as well as to other transportation professionals who are concerned with the condition and maintenance of buried culverts and storm sewers. Its objective is to determine the state of the practice of pipe assessment, the selection of appropriate repair or rehabilitation methods, and the management aspects of a pipe program. This report provides information on plastic, concrete, and metal pipes, and their appurtenances, including inlets, manholes, joints,and headwalls. It also provides information on how transportation agencies have incorporated pipe assessment and corrective work (repair or rehabilitation) into a pipe management system and eventually into the larger transportation management system. Rehabilitation specifications and methods of field report are presented as well. The study presents what management systems and methods are being used by transportation agencies to predict the service life of pipes.
