Free O5 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.

• A burst main has been repaired late on a Friday evening in a busy distributor road, and the authority wants vehicles running over the opening that night. No certified cold-lay or interim surfacing can be delivered until Monday, so the ganger proposes to backfill with the dug material, tamp it down and put a thin bituminous cap on top. Which provision covers a reinstatement made so that the road can carry vehicles straight away, and how it must be dealt with afterwards?
• A gang is reinstating a roughly square hole about the size of a paving slab in a bituminous road, hard up against a stop-valve box. A vibrating plate cannot be worked against the box, and the ganger wants to know what may go in beneath the running layer and how it can be consolidated, or spared consolidation altogether, in so tight a space. Which provision governs?
• Saw cutting has left the upright faces round a hole in a Type 3 road wet with slurry. Before the cold-lay binder course is placed, the ganger wants to check what the faces must be cleared of, how far down them a bituminous treatment has to be brushed, and which products are acceptable for it. Which provision governs?
