Integral bridge - Wikipedia

An integral bridge contains no expansion joints to accommodate enlargement due to increased temperature. Horizontal (axial) movements due to thermal expansion and braking loads are instead transferred to the fill adjacent to the abutment. The omission of the expansion joint removes a pathway for the penetration of chloride-bearing road salts to the bridge's sub-structure.

Thermal Expansion | Encyclopedia.com

THERMAL EXPANSION CONCEPT. Most materials are subject to thermal expansion: a tendency to expand when heated, and to contract when cooled. For this reason, bridges are built with metal expansion joints, so that they can expand and contract without causing faults in the overall structure of the bridge.

How does thermal expansion affect bridges? | Socratic

Thermal expansion can affect bridges with either expanding or contracting the bridge (or, by essentially distorting it's shape).. If a bridge gets very heated, the road bed will expand. On the other hand, if the bridge is cooled, the road bed will retract.

Expansion joint - Wikipedia

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