Haunching		Excavating the edge of the carriageway to about 500mm depth and replacing the materials with a new road structure.		To strengthen the road edge where it has failed, often prior to surface dressing or resurfacing.
Resurfacing/Overlay		Covering the carriageway with a minimum thickness of 40mm of dense hot laid surfacing material.		To replace a failed surface which is not suitable for Micro suirfacing or Surface dressing. Resurfacing restores ride quality, skidding resistance and can reduce noise.

Retread		Rotovating the carriageway to a shallow depth, applying additional bitumen and compacting.		To reuse existing materials from the failed road to form a new construction which can be surface dressed or resurfaced.
Recycling		In-depth recycling, remixing the existing carriageway to 500mm+ and mixing with either cement or bitumen.		To reuse existing materials from the failed road to form a new construction which can then be resurfaced.
Footway Slurry Sealing		Covering the footway with a veneer of cold laid surfacing material.		To seal the surface and restore visual/overall quality.
Footway Reconstruction		Excavating the footway to about 200mm depth and replacing the materials with a new structure.		To replace a failed footway structure.
