Expansion Joints. Bridge Engineering 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 surfaces of the plates are ush with the top of the bridge deck. The plates are generally bolted to timber deck panels or embedded with steel anchorages into a concrete deck.
To withstand the demanding requirements of bridge/highway installations, all Delastic ® Preformed Compression Seals are extruded from neoprene (polycholoroprene) compounds which satisfy the ASTM standard specification D3542 for Preformed Polychloroprene Elastic Joint Seals for Bridges. In addition to highway and bridge applications, Delastic ® Neoprene Compression Seals have also been used in GENERAL NOTES:NOTE:TWO TUBE BRIDGE RAIL Bridge Abutment Bridge Deck Expansion Joint Expansion Joint in rail 5!0 End TWO TUBE BRIDGE RAIL ELEVATION A B AASHTO LRFD Bridge Design Specifications, 7th Edition 2014. shall be ASTM A500 Grade B.

Finger joints can also accommodate minor rotations and vertical displacements across the joint. Finger joints are fabricated from steel plate, with the fingers sized to maintain minimum spacing and to minimize live load deflections.

High-Strength, Nonshrink Grout. Use high-strength nonshrink grout to fill the gap, when less than 3 in., below the bottom of the expansion joints support boxes. Provide 5,000 psi minimum compressive strength. 3.5. Concrete. Steel Sliding Plate Finger expansion joints of bridge Finger/comb/teeth type expansion joints in bridges contains steel edge profiles, featuring connection surfaces for deck waterproofing membranes, which are connected to the bridge deck by anchor loops. Finger Joints are cantilevered or simply supported steel tooth expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway
Finger joints generally are used for expansion joints larger than those that can be accommodated by strip seals. Approval of the supervising Unit Leader is required for finger joints designed for longitudinal bridge deck movements greater than 10 inches. 184.108.40.206.1 Analysis and design [AASHTO-LRFD 3.4.1, 220.127.116.11.5, 18.104.22.168, 22.214.171.124] TABLE OF SEALED EXPANSION JOINT INFORMATIONELEVATION OF ARMOR PLATE (ASTM-A36) 2 x 4 PL 1 (ASTM-A36) 2 x 4 PL 1 4" 1 4" 1 " 4 1 SEALED EXPANSION JOINT TYPE A WITHOUT OVERLAY SEJ-A 9 9 bar plate and End armor (ASTM-A36) 4 x 1 2 Bar 1 12 11 12 continuous under barrier Armor plate and joint seal installation after joint system Cast or install barrier continuous under barrier Armor plate Watson Bowman Acme Bridge Maintenance and PreservationJun 27, 2019 · Expansion joints are a critical link to the sustainability of a bridge structure. Effects of improper system selection will severely weaken the integrity of a bridge. WBA continues to enhance and improve the performance, preservation adn installation of bridge and highway joint systems.
