14.5 BRIDGE JOINTS Expansion joint devices are designed to accommodate structure movement, provide smooth and quiet passage of traffic, prevent water runoff (particularly deicing chemicals) from damaging the supporting structural elements, and provide a long service life. Article 14.5 Page 1 of 4 3/201514.5 BRIDGE JOINTS. Expansion joint devices are designed to accommodate structure movement, provide smooth and quiet passage of traffic, prevent water runoff (particularly deicing chemicals) from damaging the supporting structural elements, and provide a long service life. The following selection criteria cover the expansion joint systems most commonly used in Idaho:
Bridge Deck Expansion Joint can be applied to both concrete and steel bridge structures. USES Bridge Deck Joint Sealant is a superior high strength, elastomeric expansion joint system designed for both concrete and bridge structures. ADVANTAGES Pre-molded to ensure consistency.

This Chapter presents NDOT criteria for the design and selection of expansion joints in bridges. 19.1 GENERAL
The strip seal expansion joint is NDOTs preferred deck expansion joint system for new bridges with estimated total design thermal movements ranging from 1 in to 5 in. The contractor will select a strip seal joint from the Qualified Products List (QPL) that provides the Chapter 28 Expansion DevicesChapter 28 Expansion Devices July 2018 28-3 28.1.1 General Use watertight expansion joints wherever possible according to the design criteria and of all structure lengths . On skews over 45°, strip seals mus t be oversized to compensate for racking of the joint. For thermal movements greater than 4inches modular expansion devices are China Steel Modular Expansion Joints for Bridge China Steel Modular Expansion Joints for Bridge Construction, Find details about China Bridge Expansion Joint, Bridge Expanion Device from Steel Modular Expansion Joints for Bridge Construction - Heng Shui Kang Qiao Rubber Co., Ltd.
Steel sliding plates, shown in Figure 25.1, have been used extensively in the past for expansion joints in both concrete and timber bridge decks. Two overlapping steel plates are attached to the bridge deck, one on each side of the expansion joint opening. They are generally installed so that the top Miscellaneous Bridge Details - JBoss EAP 7Bridge Barrier Railing Type 4 and Type 5 Bridge Design Guides:Box Beam Place all details appropriate for the project, structure specific information, and the Expansion Joint Device quantity on the sheet. The sheet shall then be added to the plans as a normal plan sheet. Sizing Bridge Expansion Joints for Movement · EMSEAL Sizing Bridge Expansion JointsJoint Movement in Consideration of Lasting Joint Sealing. The lasting sealing of any expansion joint begins with the selection of a sealing material in consideration of the movement at the joint to be sealed AND the movement capability of the product being considered. This is no different in bridges.

Model Number:#SSS. Versatile System To Cover Your Needs. The Wabo®StripSeal system is a unique concept for effectively sealing expansion joints in bridges and structures. Elastomeric seals lock into a machined steel cavity for a watertight connection.Influence of the Acoustic Cover of the Modular A bridge expansion joint is a structural component designed to provide smooth passage over a gap between adjacent sides of a bridge deck. This gap is made in a purposeful way to compensate deformations in the bridge construction elements.
