BS 9227:2019

This standard BS 9227:2019 Hydraulically bound materials for civil engineering purposes. Specification for production and installation in pavements is classified in these ICS categories:

• 91.100.01 Construction materials in general

This British Standard specifies requirements for the production, installation, testing and conformity of hydraulically bound materials (HBM) conforming to BS EN 14227 for pavement applications, whether constructed by the ex-situ or in-situ methods. It also includes requirements for preliminary work at the laying site, needed to ensure that the substrate is fit to receive the HBM.

NOTE 1 The term “hydraulically bound materials” (HBM) used in this British Standard is the generic term to describe the wide range of materials comprising aggregates or soil, hydraulic binders and water; including roller compacted concrete (RCC), hydraulically bound granular material (HBGM) and hydraulically stabilized soils (HSS), which are available for use in the construction and the maintenance of roads and other paved areas.

NOTE 2 This British Standard does not include a framework for investigating and assessing existing pavements to be recycled to produce HBM.

This British Standard relates to HBM for use in pavements, including the pavement foundation. Applications related to earthworks or other uses of HBM are not covered within this British Standard.

NOTE 3 The annexes of this British Standard are informative only and do not contain provisions.
