Bridge Expansion Joint;


An expansion joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, or to allow movement due to ground settlement or earthquakes. They are commonly found between sections of sidewalks, bridges, railway tracks, piping systems, and other structures.


Road / Bridge Expansion Joints;

Expansion joints are cut into the concrete or asphalt to help with expansion and contraction of the material through the change in temperature, or due to movement of the road or bridge. The joints are cut into the structure at regular intervals to prevent it cracking or splitting. Road expansion joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber), or constructed in more elaborate ways, such as interlocking metal edges or 'spikes'.
