EN 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 Standard 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 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 pavements 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 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 intended 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 exercised 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 check 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 viscosity 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 cleanliness, 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 the 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 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.

S is the area of 100 m long slurry surfacing section, in square 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 being 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 12274-8. FPC Factory Production Control; TAIT Type Approval Installation Trial; PSV Polished Stone Value; NPD No Performance Determined 5 Requirements 5.1 Constituent materials 5.1.1 General Only constituent materials with established suitability may be used. The establishment of suitability shall result from one or more of the following: SIST EN 12273:2009



EN 12273:2008 (E) 7 a) European Standard; b) European Technical Approval; c) specifications for materials based on a demonstrable history of satisfactory use in slurry surfacing. Evidence shall be provided for their suitability. This evidence may be based on research combined with evidence from practice. 5.1.2 Binders The binder shall be a bituminous emulsion, which may be modified with polymer, in accordance with EN 13808 (see Table 1). The cohesion of the bituminous binder shall comply with the classes specified in EN 13808. For defined purposes other binders may be used, for example binders resistant to fuel spillage or pigmentable binders, which are specific to the intended use and they shall have performance characteristics complying with EN 13808. 5.1.3 Aggregates The levels and classes for aggregate properties shall be chosen from the appropriate properties and categories in EN 13043 (see Table 1). 5.1.4 Grading curves The maximum nominal size of aggregate (in mm) is declared according to  Basic set + set 1 of sieves: 2; 4; 5,6 (5); 8; 11,2 (11) or  Basic set + set 2 of sieves: 2 (or 2,8); 4; 6,3 (6); 8; 10; 12,5 (12). The design grading curve and tolerance shall be declared by the producer as part of C.3 h). 5.2 Slurry surfacing 5.2.1 Defects as determined by visual assessment The visual assessment of defects according to EN 12274-8 shall be used for the essential characteristics of adhesion of binder to aggregate, resistance to flow/deformation, hardening or setting ability, resistance to abrasion and bond to substrate and their durability (see Table ZA.1) and shall include the measurement of pavement surface macro-texture. Visual assessment of defects shall be carried out between 11 months and 13 months (see Table 1) after the installation. NOTE 1 In general most defects occur during the first twelve months after the installation of a slurry surfacing. NOTE 2 The measurement of visual assessment after twelve months gives an appreciation of the durability of the slurry surfacing and is used in the TAIT. For FPC other surrogate methods may be used if a correlation can be identified with the test used for ITT. 5.2.2 Skid resistance Skid resistance shall be assessed by macro-texture in accordance with EN 13036-1 and shall be declared from the categories in Table 1. SIST EN 12273:2009



EN 12273:2008 (E) 8 The test in EN 13036-1:2001 shall be the reference test. Other test methods may be used (for example laser texture meters – see EN ISO 13473-1) provided that they are correlated with the patch test as the reference test.

EN 12273:2008 (E) 11 Annex A (normative)
Factory Production Control (FPC) A.1 General The producer shall establish, document and maintain a Factory Production Control (FPC) system to ensure that the slurry surfacing placed on the market conforms to the stated performance characteristics. The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control incoming materials, equipment, the production process and the product. Alternative tests to those referred to in this document may be used for Factory Production Control if a correlation can be identified with the test used for ITT. Where the producer purchases constituent materials or has the slurry surfacing designed, or parts of the production or testing carried out by sub-contracting, the FPC of the supplier or sub-contractor may be taken into account. However, where this occurs, the producer shall retain the overall control of the slurry surfacing and ensure that he receives all the information that is necessary to fulfil the requirements according to this European Standard. The producer who sub-contracts all of his activities may in no circumstances discharge himself of his responsibilities to a sub-contractor. All the elements, requirements and provisions adopted by the producer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of conformity evaluation and enable the achievement of the required component characteristics and the effective operation of the production control system to be checked. Factory Production Control therefore brings together operational techniques and all measures allowing maintenance and control of the conformity of the slurry surfacing with its technical requirements. Its implementation may be achieved by controls and tests on measuring equipment, constituents, processes, machines and manufacturing equipment and finished components, including material properties of components, and by making use of the results thus obtained. A producer who has a Factory Production Control which complies with EN ISO 9001 and made specific to this European Standard shall be deemed to satisfy the requirements of this annex. A.2 General requirements The FPC system shall at least fulfil the requirements as described in EN ISO 9001 specified in Table A.1, where applicable: SIST EN 12273:2009
