What follows describes the framework for a specification that has been developed for the production, construction and testing of HBM. The full specification is similar to the 800 series of the Specification for Highway Works (SHW). Unlike the SHW however, it is applicable to the use of HBM for trench reinstatements and non-road applications such as coastal protection as well as for pavements. The full specification can be made available on request.

XX0 General Requirements
