Bridge Expansion Joint Installation
Bridge expansion joints accommodate thermal movement in the deck structure and must be installed with precision to function correctly over the bridge's design life. Installation involves cutting out existing concrete, working at the bridge edge near live traffic, and handling heavy joint assemblies with epoxy bedding compounds. This talk covers the safety controls for expansion joint installation on UK bridge projects.
Key Hazards
Falls from the bridge deck edge during joint installation and concrete removal
Silica dust from diamond cutting existing bridge deck concrete at the joint
Chemical irritation from epoxy and resin bedding compounds used in joint sealing
Workers struck by traffic when joints are installed on live carriageway bridges
Control Measures
- Install edge protection along the bridge parapet before starting joint installation work.
- Use wet cutting methods and RPE during all diamond sawing and concrete breakout operations.
- Wear chemical-resistant gloves and safety glasses when mixing and applying epoxy bedding compounds.
- Install Chapter 8 traffic management before working on joints on live carriageway bridges.
- Lift heavy joint assemblies into position using a crane or telehandler, not manual handling.
- Review the COSHH assessment for all epoxy, resin, and sealant products before application.
- Ensure adequate ventilation when applying solvent-based primers in enclosed bridge abutments.
- Brief the installation team on the joint alignment tolerances and the installation sequence.
- Record all joint installations with gap settings, temperatures, and product batch numbers in the quality log.
Remember
- Install edge protection along the bridge parapet before starting any joint work
- Use wet cutting and RPE during all diamond sawing and concrete breakout at the joint
- Wear chemical-resistant gloves when mixing and applying epoxy bedding compounds
- Install Chapter 8 traffic management before working on joints on live carriageway bridges
- Lift heavy joint assemblies mechanically rather than attempting manual handling
