This Published Document provides guidance on the use of BSEN12271 and BSEN12273 to specify products for Local Roads and for the Highways England Strategic Road Network (SRN). NOTE1 BSEN12271 speci??es the properties of surface dressing and BSEN12273 speci??es the properties of slurry surfacing, including microsurfacing. This Published Document provides guidance on the performance requirements and control procedures for the installation of both surface treatments as products for the maintenance of roads and other traf??cked areas. NOTE2 In BSEN12271 “other traf??cked areas?? include footways and cycleways. This Published Document does not apply to the following: “surface dressing works?? designed by the purchaser; i.e. surface dressing recipe specification for which the producer is instructed as to the rates of spread, chipping size, etc., and therefore is not responsible for performance requirements. NOTE3 Further guidance on the use of recipe specifications can be found in the RSTA Codes of Practice [2]; surface treatments in tunnels where ??re regulations apply; small areas under 500 m2 which are not contiguous, such as patch repairs; air??eld pavements covered by international regulations (e.g. International Civil Aviation Organization regulations); and cold applied ultra-thin surfacings (CAUTS).
