Approved Header Type Expansion Joint Systems. Select a header joint material that meets the requirements of DMS-6140:Polymer Concrete for Bridge Joint Systems; Select a class 7 joint sealant or one specified on the plans that meet the requirements of DMS-6310:Joint Sealers; Ensure joint sealers are compatible with header materials. Bridge Maintenance Manual - Iowa Department of If the open joint is a low-movement joint (that is, a relatively short bridge with only minor thermal range of expansion) and if the bulkheads and/or steel armoring on each side of the joint are in good condition, consider sealing the joint using a properly sized foam backer rod and Dow- Corning 902RCS ultra-low modulus, 100% silicone rubber joint sealant, or equal.

Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures. They stop the bridge from bending out of place in extreme conditions, and also allow enough vertical movement to permit bearing replacement without the need to dismantle the bridge expansion joint.

This process took only 2-3 days, which for an expansion joint of this size is rather fast. In the autumn of 2016, each four expansion joints with a displacement capacity of 1,760 mm and 1,200 mm, respectively, were installed at the Jianghai Bridge. Each of the expansion joints has a Finger Joints RJ Watson, Inc. - Bridge & Structural Finger Joints are cantilevered or simply supported steel tooth expansion joints.

Various expansion joint designs are also available in manganese and all rail configurations. All providing safe and reliable expansion protection against serious and costly damage to bridge joints and other adjacent track work assemblies. Easer Rail Miter Joint Design Light Traffic Slower Speeds All Rail Miter Joint Designs The Important Role Stainless Steel Expansion Joints Play In effect, stainless steel expansion joints are used to maintain building assembly functions while allowing the individual parts to move without problems. Bridges are structures that heavily rely on stainless steel expansion joints for proper function. Bridges experience a lot more movement than people realize, and they need to be properly supported. Thermal Rail Stress and Undergrade Bridges - Railway AgeAug 16, 2019 · The rail must traverse the bridge expansion joint. As the bridge tends to expand in the heat, it closes the gap at the bridge expansion joint. But the rail tends to expand also and desires to open the gap. They work counter to each others stresses at this location. For longer traditional bridge spans, a rail miter box, such as the units supplied to SEPTA by CMI Promex, is worth consideration near or at
