The type of joint system and material used depends on the maximum joint movement. During its service life, a bridge accommodates temperature changes through bearings, expansion joints, or deformation of piers and abutments. However, the wear and tear of the expansion joint material may require repair or replacement.
One of the key factors affecting the service life of bridges is how to address thermal expansion and contraction of the bridge elements. This design issue is handled in two …
Do not use elastomeric compression seal expansion joints. Design joint openings for movements associated with a temperature range of 150 F (-30 F to 120 F). For strip seal expansion joints on typical bridges, use a load factor for movement of 1.0. (Note that this value differs from the LRFD Specification based on past performance of joints in

The most popular bridge bearings and expansion joints currently used in Austra-lian road network were investigated. Bearing types include mechanical bearings, plain elastomeric bearing pads and strips, laminated elastomeric bearings, and pot bearings. Expansion joints comprise pourable seal joints, compression joint seals,
The expansion joint must be flexible enough to maintain the seal between the sections as the structure expands or shrinks due to temperature fluctuations. ... the bonding agent eventually will crack and potentially compromise the integrity of the seal material and cause the premature failure of the expansion joint. ... The two …
Gallagher Fluid Seals recently added the Rubber Expansion Joint Surveys & Failure Analysis white paper to our Resources page. This white paper discusses the importance of inspecting your plant's expansion joints. Proper design and maintenance of rubber expansion joints plays a major role in the overall preservation and lifespan of a …
BPNX is a two part bridge expansion joint system comprised of a high performance, impact absorbing, elastomeric polymer nosing, (PNSX), paired with Dowsil 902RCS silicone sealant, that together form a hard wearing, water tight expansion joint system for new bridge construction and rehabilitation of existing bridge expansion joints.
Silicone sealants have been determined to be a cheap and effective way to quickly seal joints while having a manufacturer's recommended life that matches many other available methods of sealing expansion joints. 1.2. Background on Expansion Joints Silicone sealants have been used to seal expansion joints for nearly 40 years (7, 9).

EVASEAL™ is a specialty flexible closed cell water seal that is bonded to the bridge expansion joint gap with an Australian made epoxy adhesive designed to keep water and debris from exiting the expansion joint gap. Grooves along the sides of the seal filled with epoxy adhesive allow further bond strength to the application's surface.
Expansion joints are important components in bridge structures, which are designed to accommodate the relative movement between bridge deck and abutments, ensuring the serviceability of bridges [1
The proposed guidelines with commentary should cover as a minimum: (1) joint failure mechanisms; (2) performance metrics (e.g., service life and life cycle costs (LCC)) to select the best performing joints considering bridge geometry, environmental loading, and other factors; and (3) procedures for maintenance, repair, and replacement of bridge ...

To prevent these types of failures, concrete bridge decks require joints fitted with materials that allow the structure to expand and contract without causing damage to the structu r al integrity. These are known as expansion joints, and there are many different types. Left Image -Failed Expansion Joint - Undersized. The 2 Types of Expansion Joints
DECK EXPANSION JOINTS 1.1 JOINT TYPES A variety of devices have been incorporated in the design of bridge deck expansion joints. Some of the devices have been effective while others have performed poorly. Joints can be classified into two cl assifications - open and closed. Closed joints are designed to be waterproof, while open …

putting in expansion joints," says WSDOT maintenance superinten-dent Doss Roberts. "The bridge will stand for decades, but we'll be re-pairing the expansion joints the fol-lowing year." Expansion joint maintenance is such a costly problem that many en-gineers now design jointless decks in which flexible piles, deformation of
Problems with the elastomeric parts and fasteners are best addressed through performance tests on the modular bridge joint systems as a system. Two system performance tests, an opening movement/vibration test, and a seal push-out test are suggested for the prequalification of specific modular bridge expansion joint systems.

harmful to the substructure of the bridge. Expansion joints are often one of the first components of a bridge deck to fail and repairing or replacing expansion joints is essential to . extending the life of the bridge. Failure can be due to increased traffic loading, component fatigue, low-quality work, or several other factors.
