with expansion joints at the bridge ends where bridge length exceeds these values. In situations where bridge skew angles exceed 30 degrees, consult the Bearing and Expansion Joint Specialist and the Bridge Design Engineer for recommendations and
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.
BAS Expansion Joints (NZ) has partnered with quality international manufacturers WABO® and Techstar Inc. to provide specifiers with the definitive range of expansion joints for the New Zealand Architectural, Parking/Stadium and Bridge/Highway markets.
Home » Bridge & Highway Products » Expansion Joints » Silicoflex Joint Sealing System The Silicoflex Joint Sealing System was developed as a direct response to bridge owners asking for a higher quality, longer lasting, more universal joint sealing system
The Seismic Transflex® expansion joints consist of one or two movement modules which are the "mobile" sections of the joint, made of rubber and steel, aimed to accommodate the expected movements. And the bridging module which is the "fixed" section of the joint, aimed to bridge the structural opening.

Caltrans seismic expansion joint would perform adequately under typical Bay Bridge traffic. The distress observed to the Trelleborg unit under the high loads in the last phase of testing is unlikely to occur under normal traffic.
Seismic expansion joints are suitable for ensuring water-tightness & thermal insulation in vertical & horizontal structural, seismic & abutment joints in walls of pre-cast concrete, brick, curtain-wall & stone.
Expansion joints are generally placed at various intervals to allow for the expansion/contraction of the material of the bridge (or any structure). In the case of bridges, the joint left is filled with a flexible filler that will expand/contract with the joint as it gets longer/shorter due to climate.
