Bridge Expansion Joint Guide April 2019 DESIGN Finger Joint and Modular Bridge Joint Systems (MBJS) For expansion movements greater than 5-in., but are not recommended. These systems tend to be expensive, expensive to maintain, and high maintenance. Consult with the Bridge Division on the use of these joint types. 13 Chapter 19 EXPANSION JOINTSNDOT only uses modular expansion joints where large movements are anticipated. The following will apply to the design of modular-type expansion joints:1. Expansion Movement. Modular joints should only be considered where the anticipated total expansion movement exceeds 5 in. 2. Joint Support.
warranted, a secondary sealing system may be provided below the expansion joint assembly. 19.2.3 Modular Expansion Joint Reference:LRFD Article 188.8.131.52 Modular joints are expensive and may require significant maintenance. Therefore, in the selection of modular joint systems, use only those that have been designed to facilitate the Chapter 28 Expansion DevicesFor thermal movements greater than 4inches modular expansion devices are recommended. 28.1.2 Concrete Spans An expansion device is required if the expansion length of the structure exceeds 300 feet. At this point the geometrics of the structure determine the number of expansion joints required with a maximum expansion length of 400 feet. Expansion Joints:Where, When and Howwith no expansion joints or between expansion joints R 1 = 0.15, if the building is heated and air-conditioned R 2 = 0.33, if the building is unheated R 3 = 0.25, if columns are fixed base R 4 = 0.25, if the building has substan-tially greater stiffness at one end L allow = allowable length from Fig. 1 As a general rule, expansion joints

With its support box bearing, the conventional assembled rail was improved to a monolithic rail, so this product has durability and stability improved over cumulative fatigue and has excellent waterproofing properties. Modular Joints Series 2000 - Canam-BridgesModular Joints Series 2000. Series 2000 modular joints have proven their effectiveness in hundreds of installations over the years. This joint system, which ensures the continuity of the road surface while maintaining a watertight seal during large structural movement (more than 100 mm), has been in use in Canada for more than 30 years.
SBI is equipped to engineer any number of custom expansion joint configurations including:Modular Expansion Joints Our largest project involving rail bridges is currently on-going for the I-215 Widening in Riverside - San Bernardino through Highgrove, CA. While SBI modular steel bridges are pre-engineered and pre-fabricated they are RAIL EXPANSION JOINT REJ 1200 AD - MicrosoftThis is where rail expansion joints REJ are used. The REJ 1200 advanced, in short REJ 1200 AD, was specifically developed for the heavy-duty transport field. It is based on the rail extension joints type BWG, especially the REJ 1200 with its 1200 mm (± 600 mm) extension length, which are in use since many years, but it has been enhanced in RAIL EXPANSION JOINT REJ 1200 AD - MicrosoftThis is where rail expansion joints REJ are used.
