These questions are in the practice set above. Answer them there to see the correct option and the explanation for each.
- A road is expected to carry 8 msa of traffic. Under SROH, which road category is this?
- A road on the network is expected to carry more than 125 msa of traffic. Under SROH, what does this mean for its reinstatement design?
- Scenario: an undertaker's own traffic count from several years ago suggests a road is Type 3, but the highway authority's current information places the road in Type 2. Under SROH, which classification governs?
- Scenario: a housing estate road was built a few years ago to DMRB standards under Section 38 of the Highways Act 1980, and the authority has notified the undertaker of this in advance of the works. Under SROH, how should the excavation be reinstated?
- Scenario: an undertaker is assessing a road's traffic growth rate but holds only one recent traffic assessment. Under SROH, what growth rate must be assumed until accurate information is available, and which vehicles count towards a valid traffic flow?
- A footway in a conservation area is not a principal route. It is surfaced with distinctively coloured, textured paving chosen for decorative purposes, and has been constructed and maintained to a high standard. Under SROH, which category does this footway fall into?
- A cycle track runs as part of the carriageway rather than as a separate track alongside it. Under SROH, to what standard must it be reinstated?
- Scenario: a footway is registered by the authority as high amenity, with a source of matching reinstatement material identified. Under SROH, how should the undertaker reinstate an excavation there?
- Scenario: a footway serves as a principal route with exceptionally heavy pedestrian and cycle use, but has an ordinary surface with no decorative treatment. Under SROH, which category applies?
- Scenario: the authority demonstrates that a registered high duty footway has been constructed and maintained to a standard exceeding the Code's own performance requirements, with its own declared intervention criteria. Under SROH, to what standard must the reinstatement be carried out?
