This British Standard specifies requirements for the transport, laying and compaction of those asphalt mixtures conforming to BS EN 13108-1, BS EN 13108-4 and BS EN 13108-5, described in PD 6691, from the time that they leave the mixing plant until they are placed on the road ready to receive a superimposed layer or traffic. It also includes requirements for preliminary work at the laying site needed to ensure that the substrate is fit to receive the asphalt and for the application of tack coats and bond coats. While this standard does not include explicit requirements for asphalt materials covered in other parts of BS EN 13108 or other proprietary asphalt mixtures, the general requirements of this standard may be applied to those mixtures, in addition to special requirements for particular mixtures as laid down in individual quality plans and/or method statements.
NOTE 1 The term “asphalt” used in this standard is the generic term used to describe the wide range of mixtures of aggregate and bituminous binder individually known as asphalt concrete, coated macadam, hot
rolled asphalt, stone mastic asphalt (SMA), porous asphalt or mastic asphalt and other proprietary materials which are available for use in constructing and maintaining roads and other paved areas that are on the market in the UK. Protocols for the initial type testing of asphalt materials in accordance with BS EN 13108-20 Type testing are included in Annex C, Annex D, Annex E, Annex F and Annex G.
NOTE 2 BS EN 13108-20 Type testing details the way in which the conformity of a mix composition to the requirements of the specification is to be determined. This is similar to a mix design validation or job mix trial. BS EN 13108-20 offers some choice in the way in which specimens are to be prepared for the purposes of initial type testing. Since the results determined will depend on the method of specimen preparation, a set of
protocols showing the recommended UK selection of such procedures, linked to the recommended specification levels and classes, is included in this standard.
In the case of hot rolled asphalt (HRA), requirements are specified for providing a rough-textured surface on the surface course for skid-resistance. This standard does not include requirements for asphalt incorporating bitumen emulsion binders.
