Use of Longitudinal Expansion Joints in Wide-Bridge ...

Unfortunately, the introduced longitudinal expansion joint can result in deterioration similar to that resulting from using transverse joints at bridge abutments and piers. The reason that longitudinal expansion joints are used in wide bridges is related to concerns about deck cracking resulting from constrained expansion and contraction.

Longitudinal Joint (LJ) Expansion Joint – USL Ekspan

Longitudinal Joint System. This system has been developed to provide an effective method of sealing longitudinal expansion gaps and soffits. The joint can accommodate both longitudinal and vertical movement; the 'LJ' Joint also provides a substantially watertight seal to non-trafficked gaps between structures and is available in two sizes depending on the requirements of the individual project.

Modular Expansion Joints – Ideal for Large Span Bridge Joints

Modular expansion joints for longitudinal movements of 80 mm to 1,200 mm can be widely applied on the bridges which are slope, wide, curved and skew. They are used in highway bridge decks, bridgehead and other places to prevent bridges from appearing cracks cause by climate change. It also can be used in expressway.

Evaluation of the Need for Longitudinal Median Joints in ...

Longitudinal and diagonal cracking in the deck near the abutment on an integral abutment bridge is due to the temperature differences between the abutment and the deck. Although not likely to induce cracking, shrinkage of the deck concrete may further exacerbate cracks developed from thermal effects.

Bridge Design Bridge Deck Joints

Expansion joints are prone to leak and allow the ingress of de-icing salts into the bridge deck and substructure. In general all bridges are made continuous over intermediate supports and decks under 60 metres long with skews not exceeding 30° are made integral with their abutments.

Bridge Deck Joints and Deck Joint Seals

Expansion and contraction caused by temperature changes, shortening and creep caused by prestressing, deflections caused by live loads, and longitudinal forces caused by vehicular traffic all combine to produce nearly continuous motion in highway bridges. Such movements are deceptively slow; however, the associated forces are tremendous. 1

Highway Bridge Expansion Joints Bridge Deck

Bridge Expansion Joints are an integral part of a bridge and play a vital role in ensuring the longevity of a bridge’s structural adequacy. Bridge Extension Joints enable movement and provide water tightness to bridge structures. If Bridge Expansion Joints are not correctly designed and installed, the results can be extremely costly and may end up requiring constant maintenance and repair.

Expansion joints form the load-carrying link between the abutment and the deck, or between individual decks of a bridge. Their function is to create a transition that maintains a high level of riding comfort for vehicular traffic and limits noise output from this traditionally problematic part of a bridge structure.

08.08.2012  Intact bridge decks and expansion joints also serve to shield the structural elements beneath from runoff which may be laden with salts and debris (Figure 4.2). The first priority in maintaining the deck is to provide positive drainage by maintaining open drains and scuppers. Drains can become clogged with sand and other debris from the roadside. Maintenance crews can clean out smaller
