Finger Expansion Joints on Pampanga Delta Bridge

The Pampanga Delta Bridge is an important transportation hub connecting Pampanga province with surrounding areas, handling a significant amount of traffic. Due to frequent climate changes and geological activities in the region, the stability and durability of the bridge have become key design considerations. To address the displacement and deformation of the bridge during use, the project team chose finger expansion joints as the solution.

Application Effects

Since the installation of finger expansion joints on the Pampanga Delta Bridge, it has performed excellently in several aspects:

• Vibration Damping Performance. Finger expansion joints effectively absorb vibrations caused by traffic loads and natural factors, enhancing driving comfort.
• Durability Improvement. The use of high-strength materials has reduced maintenance costs and extended the lifespan of the bridge.
• Safety Enhancement. The reduction of safety hazards caused by bridge displacement has significantly improved traffic safety.
