EN 12273:2008 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/124, Road
6、Construction Products, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 12273:2008 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an
7、 announcement in the Official Journal of the European Communities. EN 12273:2008 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of EN 12273:2008 and their corresponding national
8、standard(s). It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the end of this co-existence period, the nationa
9、l standard(s) will be withdrawn. In the UK, there is no corresponding national standard. It is important to distinguish between unmodified slurry surfacing based on unmodified bitumen emulsion and slurry surfacing that contains additives such as polymers or fibres. This National Foreword clarifies N
10、ote 1 under the terms and definitions described in Sub-clause 3.1. In the UK the term “slurry surfacing“ is used for unmodified conventional slurry surfacings and “microsurfacing“ is used for slurry surfacings that are based on polymer modified bituminous emulsions or latex modified bituminous emuls
11、ions and may have additives such as fibres. The UK industry does not differentiate between different aggregate sizes to define microsurfacing, as indicated in Note 1 under Sub-clause 3.1, although generally a coarser system is used. In the UK “microsurfacing“ is sometimes referred to as “microasphal
12、t“. The term “slurry seal“ for a fine graded, unmodified slurry surfacing, often specified as a recipe, is no longer used.

24、ean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2008, and conflicting national standards shall be withdrawn at the latest by January 2010.

BS EN 12273:2008EN 12273:2008 (E) 4 1 Scope This European Standard specifies the performance requirements and control procedures for the installation of slurry surfacing as a product for the surface treatment of roads and other trafficked areas (e.g. footways, cycleways). This European Standar
29、d is not designed for small areas of slurry surfacing on roads that are less than 500 m2 which are not contiguous (for example minor repairs). This European Standard does not apply to slurry surfacing designed by the purchaser. This European Standard is not applicable to slurry surfacing carried out
30、 in tunnels in terms of reaction to fire. No such regulations have yet been identified, nor is there any method of classification of reaction to fire. NOTE Member States can call up the technical requirements of this European Standard for use in tunnels. This European Standard is not designed for pa
31、vements that are covered by international regulations, for example, International Civil Aviation Organisation (ICAO) regulations (airfields). 2 Normative references The following referenced documents are indispensable for the application of this document.

Slurry surfacing product may consist of
38、one or more layers NOTE 1 Slurry surfacing made with larger size aggregates is often known as micro-surfacing and when made with smaller aggregates, for example less than 4 mm maximum size, is sometimes called slurry seal. Both are included in this European Standard. NOTE 2 Layers that are not inten
39、ded to be trafficked do not have to meet all performance requirements (for example macro-texture). 3.2 binder component of slurry surfacing is a bituminous emulsion which may be modified with polymer or other additives 3.3 Factory Production Control (FPC) permanent internal control of production exe
40、rcised by the producer when all the elements, requirements and provisions adopted by the producer are documented in a systematic manner in the form of written policies and procedures 3.4 design recipe and method statement to achieve the performance requirements specified 3.5 perceptible properties c
41、heck evaluation made with the senses: sight, touch, smell, hearing etc. It is a broader concept than the more commonly used term visual inspection NOTE 1 For example, a check of an emulsion delivery can involve visual (colour, consistency and homogeneity), smell (odour) and touch (estimate of viscos
42、ity by stirring and tackiness after curing). This would determine 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 cleanl
43、iness, grading or flakiness problems. (See also EN 1425.) NOTE 2 In all cases perceptible property checks should extend only as far as good practice and health and safety regulations permit. 3.6 Type Approval Installation Trial (TAIT) synonymous with Initial Type Test (ITT) which demonstrates that t
44、he characteristics of the slurry surfaces complies with the declared characteristics 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
45、period of one year. Detailed information is recorded to clearly identify the product, 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. BS EN 12273:2008EN 12273:2008 (E) 6 3.7 dura
46、bility ability of a product to maintain its required performance, under the influence of foreseeable actions, for a reasonable economic working life 3.8 producer legally responsible for placing the product on the market 3.9 product family declared group of intended uses where the declared performanc
47、e characteristics of the slurry surfacing is representative EXAMPLES Motorways, lightly trafficked roads, footways or declared by stress level. 4 Symbols and abbreviations For the purposes of this document, the following symbols apply. S is the area of 100 m long slurry surfacing section, in square
48、metres (m2); P1 the proportion of area of bleeding, fatting up and tracking in the 100 m section being considered expressed as a percentage of the area of the section; P2 the proportion of area of delamination, loss of aggregate, wearing, lane joint gaps, rutting and slippage in the 100 m section be
49、ing considered expressed as a percentage of the area of the section; P3 the proportion of area of corrugation and bumps in the 100 m section being considered expressed as a percentage of the area of the section; P4 (n) the proportion of area of the rectangle or rectangles containing small repetitive defects in the 100 m section being considered expressed as a percentage of the area of the section; L the total length of longitudinal grooves in the 100 m section, in metres (m); NOTE The above are determined by test procedures in EN
