Free O6 questions: Find It in the SROH

These questions are in the practice set above. Answer them there to see the correct option and the explanation for each.

  • An opening in a busy flexible road has been built up to binder course level, and the running surface round it is SMA. Before the permanent top layer is ordered, the ganger wants to know what it may be made of, given what is there already, and how the cut faces and the layer beneath must be dealt with first. Which provision covers this?
  • An opening in an estate street surfaced with chipped HRA is ready for its permanent surfacing. The plant asks the ganger which recipes it may send for the top layer and the layer under it, which specification they must be made to, and what size of pre-coated stone to supply for the top. Which provision covers this?
  • A long trench across a busy road used by buses, surfaced in SMA, is to be permanently reinstated. The plant asks which SMA recipes it may supply for the top layer and the one beneath, and how well they must stand up to rutting when tested. Which provision covers this?
