31、de 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. It also covers the range of proprietary asphalt mixtures which are available for use in constructing and m
32、aintaining roads and other paved areas that are on the market in the UK. However, while the general requirements of this standard will be applicable to those proprietary mixtures, there may be special requirements for particular mixtures and these will be laid down in individual proprietors Quality
33、Plans and/or Method Statements. This British Standard has been prepared by Technical Committee B/510. It supersedes BS 4987-2:2003 and BS 594-2:2003 and is a combination, rationalization and expansion of the previous requirements of those standards. In particular, it takes account of the implementat
34、ion in the UK from 1 January 2008 of European Standard specifications and attestation procedures for asphalt mixtures covered by the BS EN 13108 series (which do not deal with the laying procedures for the asphalt mixtures), as well as the European test methods for asphalt covered by the BS EN 12697
35、 series. However, as not all of the test methods previously used in the UK have been replaced by equivalent European methods, reference is made where required to retained BS 598 test methods. Requirements for transporting asphalt mixtures, for preparatory site work and for laying and compaction of a
36、sphalt mixtures, including the covering of concrete and sett paving, are given in this Standard, which also contains in the Annexes protocols to be used for initial type testing of asphalt materials in accordance with BS EN 13108-20. It has been assumed in the drafting of this British Standard that
37、the execution of its provisions is entrusted to appropriately qualified and experienced people. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does
38、 not of itself confer immunity from legal obligations. Licensed Copy: London South Bank University, London South Bank University, Thu Mar 01 08:56:08 GMT+00:00 2007, Uncontrolled Copy, (c) BSI BS 594987:2007 5 1 Scope This British Standard specifies requirements for the transport, laying and compact
39、ion of those asphalt mixtures conforming to BS EN13108 Parts 1, 4 and 5, described in BSI Published Document 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
40、at the laying site needed to ensure that the substrate is fit to receive the asphalt and for the use 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
41、 requirements of this standard may be applicable to those mixtures, in addition to special requirements for particular mixtures as laid down in individual proprietors Quality Plans and/or Method Statements. NOTE The term asphalt used in this standard is the generic term used to describe the wide ran
42、ge 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
43、 areas that are on the market in the UK. Protocols to be used in the initial type testing of asphalt materials in accordance with BS EN 13108-20 are included in the Annexes of this standard. In the case of Hot Rolled Asphalt, it also covers the procedure necessary to provide a rough- textured surfac
44、e on the surface course for skid-resistance. This standard does not include requirements for asphalt incorporating bitumen emulsion binders. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this British Standa
