How much maximum movement can a strip seal expansion joint accommodate?

A strip seal expansion joint is designed to accommodate a significant amount of movement, typically allowing for larger expansions and contractions that occur due to temperature variations and other factors affecting the bridge structure. The maximum movement that a strip seal expansion joint can handle is generally around 4 inches. This capability enables the joint to effectively manage the thermal expansion of bridge components and maintain structural integrity, reducing the risks of distress or failure in adjacent bridge components.

This design not only ensures that movement is accommodated within safe limits but also seeks to facilitate smooth vehicular passage over the joint, limiting the impact on vehicle comfort and safety. Therefore, the maximum accommodation of 4 inches is an important feature of strip seal expansion joints, making them suitable for various bridge applications where significant movement is expected.
