Thermal Rail Stress and Undergrade Bridges - Railway Age

Aug 16, 2019 · The rail must traverse the bridge expansion joint. As the bridge tends to expand in the heat, it closes the gap at the bridge expansion joint. But the rail tends to expand also and desires to open the gap. They work counter to each other’s stresses at this location. For longer traditional bridge spans, a rail “miter box,” such as the units supplied to SEPTA by CMI Promex, is worth consideration …

CWR on Steel Bridges - Transportation Research Board

Rail expansion joints are commonly used in conjunction with minimal rail anchoring to provide long open deck bridges with protection from the thermal effects of CWR. However, due to the costs associated with installing and maintaining expansion joints, as well as the high impact loads induced by the joints on the bridges, many railroads consider removing the expansion joints.

Expansion Joints In Concrete: Characteristics and Purpuse

Expansion joints are one of the important joints used in construction, like the roof expansion joints and in the paving slabs. The function of the expansion joints is to endure the stresses produced due to temperature variations. Flexible expansion joints may reduce crack formation. However, cracks developed may be repaired by using suitable sealer.
