Maintenance of Water Bound Macadam Roads:
The maintenance of water bound macadam surface consists of :
- filling potholes, ruts with additional material and adequately compacting.
- removing corrugations by dragging.
- repairing lavelled surface (in which loose aggregates appear on the road) by adding fresh binding material, watering and compacting.
- restoring broken edges by fresh material.
- renewal of surface (50-75 mm) once in 2-6 years depending upon traffic.
