Omni-Flex Pipe Joint Seals

摘要

In June, 1991 The Oklahoma Department of Transportation (ODOT) had 16 Omni-Flexpipe joint seals installed in the joints of a reinforced concrete pipe (RCP) section on ODOT Project ACIR-44-2(326)233 in Tulsa. Individual sections of RCP had diameters of 1.5 m (60 in) and lengths of 2.4 m (8 ft) in the area where the seals were installed. The remainder of the joints between RCP sections on this project were sealed with mastic. Mastic is approved for use on ODOT projects, and is widely used in Oklahoma. The 16 joints sealed with Omni-Flex seals, and an adjacent 16 joints of the same size RCP, sealed with Mastic, have been monitored since project completion. Monitoring consisted of inspecting the joints from inside the pipe. Neither section has shown any unusual amounts of leakage or other deterioration which could be considered to be related to performance of the joint seals.
