Evaluation of the On-Flex Expansion Joint Sealing System for Bridge Decks

Report No: 84-R22

Published in 1984

About the report:

Seven ON-FLEX bridge deck expansion joints were installed as experimental features on four bridges in Virginia. Each joint was evaluated with respect to its ease of installation, ability to accommodate thermal and structural movements, ability to prevent debris and water from entering the joint, and its performance over a four-year period (two years for one bridge). The joints appeared to adequately accommodate structural movements, although one appeared to be closing due, possibly, to shifting of the bridge superstructure or the abutment. The joints prevented debris from entering the normal joint opening but they were not completely waterproof.
