JOINT SEALING PRACTICE FOR LONGER SPANS

A FORESEEABLE TREND TO LONGER SPAN BRIDGES TOGETHER WITH THE REALIZATION THAT THERE IS A DEFINITE, CAUSAL RELATIONSHIP BETWEEN CERTAIN IDENTIFIABLE TYPES OF PREMATURE BRIDGE DISTRESS AND INEFFECTIVE SEALING PRACTICES HAS LED TO THE RECENT DEVELOPMENT AND USE OF A NUMBER OF INTERESTING NEW SEALING SYSTEMS USING THE COMPRESSION PRINCIPLE. A PHOTOGRAPHIC STUDY OF PREMATURE BRIDGE DISTRESS HAS BEEN ACCOMPLISHED IN AN ATTEMPT TO BETTER UNDERSTAND WHAT IS HAPPENING AND WHAT CAN BE DONE TO ELIMINATE OR AT LEAST MINIMIZE THE PROBLEM. A PERFORMANCE CRITERION FOR A SEALING SYSTEM HAS BEEN ESTABLISHED TO ASSIST BRIDGE DESIGN ENGINEERS IN THE SELECTION OF AN EFFECTIVE SEALING SYSTEM FROM THE AVAILABLE CANDIDATES. TYPICAL SOURCES AND CATEGORIES OF MOVEMENT PHENOMENA ON BRIDGES ARE DESCRIBED AND THEIR IMPORTANCE UNDERSCORED IN LONG-SPAN JOINT SEALING PRACTICE. IT IS THE RESPONSIBILITY OF THE DESIGN ENGINEER TO IDENTIFY, DESCRIBE AND PREDICT THE MAGNITUDE OF EACH OF THE TYPES OF MOVEMENT THAT MIGHT OCCUR AT THE JOINT INTERFACES ON THE STRUCTURE. EXAMPLES OF CURRENT SEALING SYSTEMS AND SOLUTIONS IN THE UNITED STATES AND EUROPE ARE ILLUSTRATED AND DISCUSSED IN TERMS OF THEIR PERFORMANCE CAPABILITIES. /AUTHOR/
