Highway & Pavements

Site won fill materials can then be stabilized to produce a higher strength Firmabase material which greatly reduces or fully replaces stone subbase and capping layers. By selecting suitable granular materials, in-situ Firmabase techniques can also be used to create roadbase (CBM) layers. The stabilised Firmabase layer can be created in varying thicknesses to suit applied loading and underlying soil strengths. Firmabase can bemade frost resistant,meaning that the total earthworks can be designed within the heave layer.

All of the Highway Pavement and design is carried out to Appropriate National Standards and Specification. Please see section on Design for further design details
