DEBRIS REMOVAL FROM CONCRETE BRIDGE DECK JOINTS

A practical and effective technique for cleaning joints on concrete bridge decks was developed. It employs commercially available high-pressure water-jet equipment and a small simply constructed cart which facilitates operator control of the water jet. The technique was tested by Texas Highway Department maintenance personnel on in-service bridges and found to be far superior to other joint cleaning methods. An investigation of several techniques for widening very narrow or completely closed bridge joints was made. With current technology, it appears that suitable equipment could be designed; however, it will require an extensive developmental effort which is not believed to be warranted at this time.
