Study Notes
Highway Maintenance and Rehabilitation
- Routine work to keep pavements in good condition
- Monitoring pavement health is crucial
- Maintenance actions slow deterioration
- Identifying and addressing pavement deficiencies
- Surface maintenance: repairs and upkeep of roadways
- Roadside maintenance: maintaining areas around roads
- Shoulder and approaches maintenance: includes public roads, private driveways, ramps, speed change lanes, turnouts
- Bridge, tunnel, and drainage maintenance: maintaining structures
- Traffic controls and safety devices: road signs, markings, signals, lighting
- Maintenance of bituminous surfaces: dealing with weathering, base/subgrade failure, material quality and compaction issues
- Maintenance of PCC surfaces: repairs for filled/sealed joints, cracks, spalled/scaled/cracked areas, patching
- Treatment of buckled/settlement damaged pavement
- Maintenance of shoulders and approaches
- Maintenance of roadsides: includes areas between travel surface and right-of-way
Bridges, Tunnels, and Structures
- Minimizing deterioration or repair of damage from accidents, floods, and events
- Steel bridges need cleaning and repainting
- Concrete bridge decks may deteriorate due to corrosion
- Bridge deck with minor deterioration may be patched
- Decks with major deterioration can be replaced or overlayed
Pavement Rehabilitation
- Proper maintenance extends pavement life
- Pavement rehabilitation is needed when deterioration warrants it
- Conventional rehabilitation: all new materials
- Patching/overlaying: using new wearing surfaces and pavement
- Pavement milling: method to remove & replace layers
- Pavement recycling involves transforming degraded pavement into homogenous structure
Traffic Control and Safety
- Devices like guardrails, impact barriers, and attenuators
- Pedestrian overpasses/underpasses, fences
- Safety devices should be frequently inspected and repaired
