BRIDGE EXPANSION JOINTS
An expansion joint or movement joint is an assemblage designed to safely soak up the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts jointly, or to allow movement due to ground arrangement or earthquakes. 






They are usually found between sections of buildings, bridges, sidewalks, railway tracks, piping systems, ships, and additional structures.





 Building faces, concrete slabs, and pipelines enlarge and contract due to warming and cooling from seasonal difference, or due to other heat sources.





 Before expansion joint gaps were built into these structures, they would crack underneath the stress induced.
