along the length of the expansion joints . The movement is not solely in the longitudinal direction. The acute corners of a bridge with parallel skewed supports tend to expand and contract more than the obtuse corners, causing the joint to rack. Racking should be limited to 20 percent of the rated movement of the joint. For bridges with expansion
Bridge deck expansion joints are divided into the following three groups. 1. Modular expansion joint systems including finger and sliding plate dams, with 2 to 16 in. of movement, but generally more than 13 in. of movement. S. H. Dahir, Pennsylvania State University, Middletown, Pa. 17057. Bridge Expansion & Movement Joint Systems Emseal ServicesA variety of proprietary joint types are available to suit different structure types and movement ranges. Expansion joints, and their constituent components, generally have a working life significantly shorter than the design working life of the structure itself, hence thought needs to be given at the design stage of how the joints are to be maintained or replaced, while minimising delay or
other bridge expansion joint that can beat Thormajoint for effectiveness, economy and reliability. A special combination of an elastomer modified BJ200 binder and carefully selected single size BJ stone, provide a strength and flexibility that can accommodate horizontal movements up Bridge construction expansion joint - All architecture and elastomeric expansion joint TENSA-GRIP RS & RS-LS. steel for bridge construction road. elastomeric expansion joint. TENSA-GRIP RS & RS-LS. Possible movement:80, 100 mm. mageba TENSA-GRIP expansion joints are single gap joints for movements of up to 80 mm in the case of type RS, or 100 mm in the case of Type RS-LS.

Longitudinal Joints:Joints parallel to the pave ment centerline that control cracking and delineate lanes of traffic. 4. Isolation and Expansion Joints:Joints placed to allow movement of the pavement without dam aging adjacent pavements, intersecting streets, drainage structures, or other fixed objects. Transverse Contraction Joints
EXPANSION JOINTS Large Movements GRANOR® / ETIC Aluminium Finger Joints - Series EJ (Installation for skewed line of movement shown) The Granor ETIC® EJ series Saw Tooth Finger joints are robust watertight Bridge deck expansion joints that accommodate larger movements up to 300mm total capacity. Expansion Joint Systems Structural Rubber ProductsProviding a rated movement of up to 4, the SS40 is an industry standard design that can be modified to accommodate roadway skews, turn-ups, and laybacks. Key features include:Parapet to parapet continuous membrane; Membrane convulutions transfer minimal stress across the expansion joint at all movement ratings. Water-tight seal
Bridge expansion joints (or movement joints) are designed to enable continuous traffic between two structures and are necessary to accommodate structural movements due to creep and shrinkage effects, temperature variations or deformations under live load. They are suitable for reinforced concrete, pre-stressed concrete, composite and steel structures, and particularly for bridge decks. Finger Joints RJ Watson, Inc. - Bridge & Structural RJW Finger Joints are a simplistic design with no moving parts that are designed to accommodate any bridge deck expansion joint movement. Finger Joints are cantilevered or simply supported steel tooth expansion joints. They are comprised of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths.
Asphalt expansion joints are generally installed on road bridges where the distance between adjacent expansion joints does not exceed 50 m provided that the required moving capacity amounts to maximum 50 mm or to such a value that is guaranteed by the manufacturer. Modular Expansion Joints Ideal for Large Span Bridge JointsModular expansion joints, also called GQF-MZL modular bridge joints, are composed by boundary beams, middle beams, cross girders, displacement control systems, bridge bearings, anchoring components and rubber sealing belts. modular expansion joints are suitable for longitudinal movements of 80 mm to 1200 mm.. Having good bearing capacity and stability, modular expansion joints

water away from important bridge components, joints and joint seals play a big role. Bridge joints are typically placed over supports or at the ends of the bridge above the bearings. The joints allow for the effects of thermal expansion of the bridge while directing water from the deck off to the sides of the bridge. US6912751B2 - Expansion joint system for accommodation An expansion joint system which is provided to accommodate forces applied to highway construction during normal changes in ambient conditions, and which is also designed to withstand seismic forces and vehicular forces, which may be applied in transverse and longitudinal directions.

An expansion joint system which is provided to accommodate forces applied to highway construction during normal changes in ambient conditions, and which is also designed to withstand seismic forces and vehicular forces, which may be applied in transverse and longitudinal directions. The system includes spaced-apart transverse vehicle load bearing members which are placed in a gap defined mageba modular expansion joints the benchmark for small or large transverse movements. The table below presents the maximum movement capacities of various sizes of TENSA®MODULAR expansion joint, in the longitudinal and transverse directions. Transverse movements are considered Skewed orientation and movements Expansion joints are typically installed perpendicular to the bridges axis, with
Large movement expansion joints, particularly of the Modular type having movement capacities up to 2,000mm, require careful consideration as to the structural integrity of the bridge in this highly stressed area. Typical blockout depth is in the order 0f 400mm. Careful consideration is
