20、n of surface dressing as a product for the surface treatment of roads and other trafficked areas. This European Standard does not apply to surface dressings designed by the purchaser. This European Standard is not applicable to surface dressings carried out in tunnels and where fire regulations appl
21、y. This European Standard does not apply to small areas of surface dressing on roads that are less than 500 m2which are not contiguous (for example patch repair surface dressing especially when carried out manually). This European Standard does not apply to aircraft pavements that are covered by int
22、ernational regulations, for example, International Civil Aviation Organization (ICAO) regulations (airfields). 2 Normative references The following referenced documents are indispensable for the application of this document.

28、inder and at least one layer of chippings 3.2 binder binder as a component of surface dressing is a bituminous material such as: bitumen emulsion; fluxed bitumen; cut-back bitumen; or paving grade bitumen; any of which may be modified with polymer 3.3 chippings coarse aggregate practically free of f
29、ines with a narrow grading range 3.4 pre-coated chippings chippings coated with bituminous binder before application 3.5 mosaic arrangement of the chippings such that they are in shoulder to shoulder contact and are thus supported laterally NOTE The initial stability of a surface dressing is depende
30、nt upon the formation of a close mosaic and the cohesion and adhesivity of the binder. Subsequent durability is gained by re-orientation of the chippings by traffic to form a tight mosaic, and sufficient binder to secure the chippings to the existing road surface. 3.6 embedment process whereby chipp
31、ings are forced into an existing road surface by the action of traffic NOTE 1 Factors affecting embedment are: traffic density of heavy vehicles during summer months; average road temperature and road hardness. Cement concrete, for example, does not allow embedment; size of chippings. Larger chippin
32、gs reduce the rate of embedment; traffic speed. Slow moving traffic, experienced on hills and at junctions, increases embedment. Conversely, fast traffic in the overtaking lane of a dual carriageway results in less embedment; shaded areas. A reduction in average road temperature reduces embedment. N
33、OTE 2 Embedment results in a reduction of macrotexture with time (macrotexture is measured in accordance with EN 13036-1 or EN ISO 13473-1). 3.7 Factory Production Control permanent internal control of production exercised by the producer when all the elements, requirements and provisions adopted by
34、 the producer are documented in a systematic manner in the form of written policies and procedures NOTE This production control system documentation ensures a common understanding of quality assurance and enables the achievement of the required product characteristics and the effective operation of
35、the production control system to be checked. 3.8 design proposal design proposed (components and method statement) to provide the performance requirements specified BS EN 12271:2006EN 12271:2006 (E) 6 3.9 perceptible properties check evaluation made with the senses: sight, touch, smell, hearing etc.
36、 It is a broader concept than the more commonly used term visual inspection NOTE 1 For example, a check on a binder delivery might involve visual (colour, fuming, consistency and homogeneity), smell (odour) and touch (estimate of viscosity by stirring and tackiness when cured and at ambient temperat
37、ure). This would detect whether the binder conformed to the expectations of the tester and would be the quickest way to detect a defective load. Similar principles apply to aggregates, particularly with stockpile inspection where handling soon reveals cleanliness, grading or flakiness problems. NOTE
38、 2 In all cases perceptible property checks should extend only as far as health and safety regulations permit. 3.10 Type Approval Installation Trial (TAIT) synonymous with Initial Type Test (ITT) which demonstrates that the characteristics of the surface dressing complies with the declared character
39、istics according to this European Standard. The TAIT consists of a defined section where surface dressing has been installed using Factory Production Control (FPC) and which has been submitted to performance tests after a period of one year. Detailed information is recorded to clearly identify the p
40、roduct, its performance and the intended uses (see Annex C) NOTE A TAIT is used by the producer to provide confidence in his product and his capability to design and install it. 3.11 road grade intended use which may have set frequencies of testing and/or set categories of performance (see Annex C)
41、3.12 product family represents a declared sub-group of intended uses and/or associated parameters described by the appropriate road grade (see Annex C) 3.13 single surface dressing (see Figure 1a) successive laying of one layer of binder and one layer of chippings 3.14 racked-in surface dressing (se
42、e Figure 1b) successive laying of one layer of binder and two layers of chippings, the second layer being of a smaller size 3.15 double dressing (see Figure 1c) successive laying of a first layer of binder and a first layer of chippings followed by a second layer of binder and a second layer of chip
43、pings, the second layer of chippings being of a smaller size NOTE When the surface dressings are not carried out at the same time (i.e. successively), they are considered as two single dressings. 3.16 inverted double dressing (see Figure 1d) successive laying of a first layer of binder and a first l
44、ayer of chippings followed by a second layer of binder and a second layer of chippings, the second layer of chippings being of a larger size NOTE When the dressings are not carried out at the same time (i.e. successively), they are considered as two single dressings. 3.17 pre-chipping dressing (see

47、e, under the influence of foreseeable actions, for a reasonable economic working life 3.20 defect state of a surface dressing where the mosaic is covered by binder as in the case of fatting up, tracking and bleeding (P1); or is disrupted as in the case of scabbing and tearing (P2), fretting (P3) or
48、streaking (P4) NOTE 1 For further clarification see EN 12272-2. NOTE 2 A defect can occur due to poor construction techniques.
