The preferred method for compaction in small openings and narrow trenches is in accordance with S10. This must be followed unless there are restrictions, such as kerbs, ironwork, street furniture, that do not allow it. Where these restrictions pre-exist, hand compaction may be used, but only if demonstrated to be appropriate. It is deemed appropriate if:
  1. the width of the reinstatement is the width of the compaction tool sole plate plus a minimum of 30 mm; and
  2. the performance requirements of S2 are met, unless agreed otherwise with the authority.
If hand compaction is not demonstrated to be appropriate, Polymer Modified Mastic Asphalt (PMMA) as per S6.5.6 to S6.5.10 may be used.
