There are different types of bridge rehabilitation, depending on the state of the bridge and the specific needs for repair or improvement. Here are some common types of bridge rehabilitation:
1. Deck rehabilitation: This involves repairing or replacing the bridge deck, which is the top surface that supports vehicle traffic.
2. Structural rehabilitation: This involves repairing or replacing structural elements of the bridge, such as beams, columns, or piers, to strengthen the bridge and restore its load capacity.
3. Seismic rehabilitation: This involves upgrading the bridge to withstand seismic activity by retrofitting or improving its structural elements and connections.
4. Expansion joint rehabilitation: This involves repairing or replacing the expansion joints, which allow the bridge to expand and contract with temperature and movement.
5. Surface treatment or protective coating: This involves applying a protective coating to the bridge to prevent corrosion and prolong its lifespan.
6. Abutment and wing wall rehabilitation: This involves repairing or replacing abutments and wing walls, which are the support structures at the ends of the bridge.
7. Rehabilitation of bearings: This involves replacing or repairing bearings, which are the components that allow the bridge to move and adjust to loads and movements.
8. Rail rehabilitation: This involves repairing or replacing railings and barriers, which provide safety for vehicles and pedestrians.
9. Upgrade of lighting and electrical systems: This involves improving lighting and electrical systems on the bridge, which can improve visibility and safety during night and low-visibility conditions.
