Expansion Joints

Home»Bridge & Highway Products»Expansion Joints

RJ Watson has 25 years of worldwide experience in the successful design and installation of hundreds of expansion joint systems for bridges and highways

Bridge expansion joints are designed to allow for continuous traffic between structures while accommodating movement, shrinkage, and temperature variations on reinforced and prestressed concrete, composite, and steel structures. They stop the bridge from bending out of place in extreme conditions, and also allow enough vertical movement to permit bearing replacement without the need to dismantle the bridge expansion joint.

RJ Watson has developed and installed Expansion Joint Systems on multitudes of bridges, highways and parking decks throughout the world.   The Silicoflex Joint Sealing System is an innovative highway and bridge expansion joint system that is cost effective, easy to install and offers a long, effective sealing life. 

RJW Finger Joints for are cantilevered or simply supported steel tooth bridge expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths.  

SilTron is a two-part, cold-applied, self-leveling, fast-curing, ultra-low modulus, 100% silicone material designed for sealing of concrete pavement joints experiencing thermal movement. ZED Seal is an enhanced co-polymer foam designed to give greater resilience and higher tensile and tear performance.

Silicoflex Joint Sealing System

The Silicoflex Joint Sealing System is an innovative highway and bridge expansion joint system that is cost effective, easy to install and offers a long, effective sealing life.

RJW Finger Joints

RJW Finger Joints for are cantilevered or simply supported steel tooth bridge expansion joints. They are composed of pairs of independent elements with parallel teeth provided in lengths from 3 feet to full roadway widths. 

ZED Seal

ZED Seal is an enhanced co-polymer foam designed to give greater resilience and higher tensile and tear performance. ZED Seal will permanently bond to concrete, steel or elastomeric concrete expansion joint surfaces.

Poly-Tron Elastomeric Concrete

Poly-Tron is an easy to mix,  three component, modified polyurethane elastomeric concrete. Poly-Tron is used primarily as an expansion joint edge material. 

SilTron

SilTron is a two-part, cold-applied, self-leveling, fast-curing, ultra-low modulus, 100% silicone material designed for sealing of concrete pavement joints experiencing thermal movement.

We will test your joints

A 2 million cycle fatigue test was performed on an RJ Watson finger joint. The universal test fixture with a long actuator was used to repeat the 28 kip axial load. The 6.25 mile cumulative sliding test was performed successfully on the large movement finger joint specimen. Total displacement exceeded 32 inches employing our large stoke actuator which easily accommodated this displacement. The fixture contained aggregate on the slide surface which provided a realistic wear simulation for the test.

 

RJ Watson is located outside of Buffalo, NY and  has a state of the art 70,000 square foot facility for engineering, fabrication and testing of bearings, joints and other structural devices
