The purpose of an expansion joint on a bridge it to permit the components to expand and contract with changing temperatures without stressing the entire bridge structure. Early bridge failure would be the result of building a modern bridge without expansion joints.

What is the difference between Rubber Expansion joint and Dismentaling joint?
rubber expansion joint is a rubber and dismentaling joint is mental joint
What is the purpose for placing some type of expansion material between the repair material and the old joint?
allows for a better seal
How do you provide expansion joint in slab beam construction 75 meters in length?
The purpose of expansion joint , is to anticipate movement of structure due to temperature, earthquake,settlement. In 75 mtrs length of slabs we can make expansion joint in L/2 or 75/ 2 or L/ 3 for every 25 mtrs , we provide bearing Pads for movement. , actually this also name as movement joint.
When was Expansion Joint Manufacturers Association created?
Expansion Joint Manufacturers Association was created in 1955.
Where does the name dog bone expansion joint come from?

How do you install expansion joint in reinforced concrete?
Expansion joint's specification depends structure to structure. It depends upon its use rather the purpose it is for. Material used for expansion joint is Neoprene sheet of 50mm thick. Basically material should porous & medium density. Eg. While connecting two different super structure viz. column, we can keep the sheet between the reinforcement of two columns tieing the sheet with binding wire & r/f. Debdutta
Why would a bridge contain gaps where the metal pieces fit together?
these gaps "joint" are used to prevent cracking due to expansion and contraction which result from the change in temperatures between summer and winter and night and day
What is application of expansion joint?
Expansion joints include: PTFE expansion joint, Rubber expansion joint, Metallic expansion joint, and Fabric expansion joint. visit website: www.rubbersealing.comPTFE expansion jointThe PTFE expansion joints are unreinforced PTFE that come standard with iron 150# drill flanges. Stainless flanges are available. They are avaialable in 2, 3, or 5convolutions of varing movements. The 2-convolution joint is sometimes referred to as a "coupling".Molded flexible couplings and expansion joints of PTFEdesigned to help protect pumps, compressors and other expensive equipment.Bellows-type flexible couplings and expansion joints are contour molded of black PTFE by a patented process. They are corrosion resistant, non-aging, with extraordinary flex life and unmatched reliability. These superior units cost no more than those made of lesser materials. The flexible element is formed over the full sealing face of the end flanges eliminating troublesome separate gaskets.Note the change in pressure rating with
