BS 5931 is a code of practice that gives information and recommendations about the use of extruded-asphalt or extruded-concrete, and slip-formed concrete road-edge features such as kerbs or channels.
Details of asphalt and concrete mixes that are suitable for the processes are given together with construction details.
Note: BS 5931 does not provide recommendations for the forming of such edge features monolithic-ally with paved areas nor on the forming of safety barriers.
BS 5931 on ‘in situ edge details for paved areas ’ is useful for:
Most forms of road-edge detail may be successfully extruded or, for concrete alone, slip formed. Raised kerbs may be formed on both rigid and flexible pavements during new construction projects.
The principle use of machine laid in situ sections in the United Kingdom has been at the back of hard shoulders on motorways as a drainage detail. BS 5931 guidelines help you to adopt in situ sections for
Machine laid in situ sections using BS 5931 guidelines can be laid at up to ten times the rate of laying for conventional forms of kerbs. The in situ type of kerb discussed in BS 5931 may be superimposed on existing kerbs thus avoiding taking up and relaying to new levels.
BS 5931 guidelines help you to facilitate efficient laying of in situ sections that make roads and pavements more practical for use.
