Roads, Footways & Layers

Free O3 questions: Roads, Footways & Layers

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

• Scenario: the highway authority's current information places a quiet residential street at 0.4 msa. Under SROH, which road category must the reinstatement be designed for?
• Under SROH, once a road's category has been settled, what does the Code itself go on to settle about the reinstatement's design?
• Scenario: an opening runs from the carriageway, across a grass verge and onto an area of unmade ground. The ganger says the Code's layer thicknesses apply to the carriageway length only. Under SROH, is that right, and why?
• Scenario: a cycle track built and maintained to a high standard is surfaced in a bituminous material given a particular texture and a distinctive coloured finish. Under SROH, which category does it fall into, and on what basis?
• Scenario: a town-centre regeneration is expected to change traffic patterns so that commercial vehicle numbers on a street rise sharply. Under SROH, what may the traffic growth rate used for the reinstatement design be based on?
• Under SROH, in what order does the Code set out the normal sequence of operations for an undertaker's works?
• Under SROH, what is a road structure classified as flexible, composite, rigid or modular for?
• Scenario: an undertaker could finish a carriageway opening permanently at the first visit, but proposes to leave an interim surface and come back later purely to suit its own programme. Under SROH, what does the Code expect of it?
• Scenario: on a carriageway opening the backfill, sub-base and base are reinstated permanently at the first visit, and an interim binder course and surface course are laid above them. Under SROH, what may those interim layers be made of?
• Scenario: an opening through a concrete road slab exposes a hydraulically bound layer sitting immediately below the underside of the slab, and the operative has to know where the backfill ends and the sub-base begins. Under SROH, how is that layer treated?
