PERMANENT ROADS AND PARKING AREASThe standard design consists of a 320mm single stabilised capping & sub-base (to IAN 73/06). This is a non-frost susceptible replacement layer with an end performance strength of 150MPa (30% CBR) which converts to approx. 260 KN/m2 upon which floor slabs and surfacing can be laid directly. Sub grade improvements and dual layer systems also available.
Permanent Surfacing or Slab Design
Asphalt can be laid directly onto the stabilised layer; no type one regulating layer is required with achievable tolerances of +/–10mm. This is suitable for permanent or long term works.
Conversion to Permanent Roadway
Temporary haul roads can also be constructed to Highways Specifications and used as the capping and sub base for permanent roads after their requirement as a haul road has expired. The area is simply regraded and asphalt can be laid directly onto the stabilised layer.
