BS EN 12273:2008 Slurry surfacing. Requirements

BS EN 12273 specifies the performance requirements and control procedures for the installation of slurry surfacing as a product for the surface treatment of roads and other trafficked areas (e.g. footways, cycleways).

BS EN 12273 is not designed for small areas of slurry surfacing on roads that are less than 500 m2 which are not contiguous (for example minor repairs).

BS EN 12273 does not apply to:

  • Slurry surfacing designed by the purchaser
  • Slurry surfacing carried out in tunnels in terms of reaction to fire. No such regulations have yet been identified, nor is there any method of classification of reaction to fire
  • Pavements that are covered by international regulations, for example, International Civil Aviation Organisation (ICAO) regulations (airfields).

Slurry surfacing is surface treatment consisting of a mixture of aggregates, bituminous emulsion water and additives, which is mixed and laid in-place. Slurry surfacing product may consist of one or more layers
