1 Scope
This British Standard specifies requirements for materials processed with either bituminous emulsion , foamed bitumen or hydraulic material , including their design and composition, production, installation and performance testing.
This British Standard includes requirements for mixtures prepared using bituminous binders that may also contain hydraulic material .
This British Standard describes a number of processes and methods by which existing material in the road or other paved areas is either processed in-situ or uses recycled material processed ex-situ.
NOTE 1 BS 9227 specifies requirements for the production, installation, testing and conformity of hydraulically bound materials ( HBM ) conforming to BS EN 14227 Parts 1 to 5 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 . BS 9227 includes only materials conforming with BS EN 14227 Parts 1 to 5 whether from recycled or virgin materials. For the recycling of pavements, TRL Report TRL 611 [1] can be used.
NOTE 2 BS EN 13108-31 specifies requirements for asphalt concrete using aggregate conforming to BS EN 13043 and bituminous emulsion for use on roads, and other trafficked areas.
