roadway bridge expansion joint with large movement

19. Expansion Joints and Bearings

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

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

Key features include:Parapet to parapet continuous membrane; Membrane convulutions transfer minimal stress across the expansion joint at all movement ratings. Water-tight seal

Expansion Joints Bridge Expansion Joint Installation

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.

GUIDELINES FOR ROAD DESIGN, CONSTRUCTION,

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.
