Carbon FRP Strengthening of PCCP Aqueducts

Abstract

The paper discusses the Providence Water Supply Board's evaluation of a main water pipeline condition by using nondestructive testing. This evaluation program was necessary because a portion of the prestressed concrete cylinder pipe (PCCP) water main blew out in Cranston, Rhode Island in November 1996 releasing 57 to 76 million liters (15 to 20 million gallon) of water through residential streets; and the possibility that another section of the pipe may not be able to resist the design forces. This paper provides a description of the design, application, and full-scale load testing of the FRP liner for the rehabilitation of the pipeline.
