Title: Improvements in Expansion Joint Sealing Performance for Parking Structure Applications

Abstract:Effective sealing of expansion joints in parking structures requires a thorough understanding of structural behavior and the service condition, as well as the properties and limitations of available expansion joint systems. Factors contributing to volume change, traffic conditions, detailing, and installation will all play a role in the ultimate success of the joint system selected. Commercial types of expansion joint seals commonly available include the urethane "T" joint, compression seals, steel and aluminum strip seals, winged seals with headers, and inflated structural seals. Each have certain advantages and limitations which must be considered relative to the usage condition in order to make a proper selection. Detailing considerations, such as joint opening size, movement considerations, traffic volume and loading, directional change, and termination requirements and drainage patterns all have an impact on performance. Periodic maintenance should be expected and planned for through an established program. Today, a wide variety of effective expansion joint sealing systems are available to help avoid the many problems previously associated with parking structure applications. Success depends on understanding the requirements of the service condition and the limitations of the various systems considered for use. Only with care in the specification and detailing of expansion joint requirements at the design stage will the installing contractor be positioned to most effectively install any expansion joint system.
