Method C – Permanent base reinstatement
- The backfill, sub-base and base must be reinstated to a permanent standard at the first visit.
- The interim surface course and part or all of the interim binder course may be deferred set material. Part or all of the entire interim binder course may be an unbound granular material.
- On the second visit, all interim surfacing materials must be removed to the top of the base, and a permanent binder course and surface course must be laid.
