EN 13108-2:2016 (E) 6 Introduction The aim of this European Standard is to enable specification of Asphalt Concrete for Very Thin Layers mixtures on a performance basis. In general, however, there are currently more empirical tests available to describe the mixtures. Depending on the experience with the combination of requirements in this European Standard more or less degrees of freedom for the producer may be given. This European Standard covers a large variety of materials for different applications, traffic and climate conditions. EN 13108-2 gives properties and listings of possible categories. It has to accommodate the road industry for all of Europe. For this reason the menu approach for properties has been chosen. The tables represent categories that are required all over Europe. For this reason numerical values in tables do not always obey statistical rules. Based on conditions of use specific properties and categories may be defined in documents related to the application of the product. The categories defined in those documents need to take into account the reproducibility of the test when this is given in the appropriate test method. Care should be taken to only select those tests which are relevant to the application of the asphalt and the use of the pavement and to avoid a combination of potentially conflicting requirements. SIST EN 13108-2:2016



EN 13108-2:2016 (E) 7 1 Scope This European Standard specifies requirements for mixtures of the mix group Asphalt Concrete for Very Thin Layers for use on roads, airfields and other trafficked areas. Asphalt Concrete for Very Thin Layers is a bituminous material, of which the composition and the grading of the aggregate is selected for application of the material in very thin layers with a thickness of 20 mm to 30 mm. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by this standard. Asphalt Concrete for Very Thin Layers is used for surface courses. This European Standard includes requirements for the selection of the constituent materials. It is designed to be read in conjunction with EN 13108-20 and EN 13108-21. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For all constituent materials the properties relevant to the performance of the mixture shall be made available. The establishment of suitability shall result from one or more of the following: — European Standard; — European Technical Assessment; — Specifications for materials based on a demonstrable history of satisfactory use in asphalt. Evidence shall be based on research and/or the evidence of satisfactory practical use. In documents related to the application of the product details for the assessment of this proof may be defined. There can be technical limitations regarding the future recycling possibilities. Also traceability of the nature of constituent materials can affect the potential for future recycling. 4.2 Binder 4.2.1 General The binder shall be a paving grade bitumen, a modified bitumen, a multigrade bitumen or a blend of one of them with natural asphalt. The paving grade bitumen shall conform to EN 12591, the modified bitumen to EN 14023 and the multigrade bitumen to EN 13924-2. When natural asphalt is used, it shall conform to EN 13108-4:2016, Annex B. Premixed binders that are not covered by EN 12591 or EN 14023 or EN 13924-2 can be used provided that information is given as stated in 4.1, and that the base bitumen is conforming to EN 12591 or EN 14023 or EN 13924-2. The use of these binders may be defined in documents related to the application of the product. 4.2.2 Selection of binder 4.2.2.1 General Depending on the conditions of use, the type and grade of modified bitumen and the amount and category of natural asphalt may be specified, may be defined in documents related to the application of the product. The type and grade of the bitumen and the amount and category of natural asphalt shall be declared in the Type Test report. NOTE EN 14023 for modified bitumen is a framework for classification and is only meant to characterize the modified bitumen. The modified bitumen specifications are not performance based. The same applies to multigrade bitumen according to EN 13924–2. When an additive is used to lower the production temperature of the Very Thin Layer Asphalt Concrete and thereby changes relevant properties of the binder at temperatures representative for the climatic conditions in the place of use, evidence shall be provided to show what the influence of the additive is on the performance of the mix. This proof shall be based on research or evidence of satisfactory performance according to 4.1. SIST EN 13108-2:2016



EN 13108-2:2016 (E) 12 4.2.2.2 Surface courses with reclaimed asphalt When using more than 10 % by mass of the total mixture of reclaimed asphalt from mixtures in which only paving grade bitumen has been used and when the binder added to the mixture is a paving grade bitumen and the grade of the bitumen is specified, the following requirements may be defined in documents related to the application of the product. The penetration and/or the softening point of the binder in the resulting mixture, calculated from the penetrations and/or the softening points of the added binder and the recovered binder from the reclaimed asphalt, shall meet the penetration or softening point requirements of the specified grade. The calculation shall be performed according to Annex A. In some cases the binder of the reclaimed asphalt can be so hardened that a very soft bitumen shall be chosen to fulfil these requirements. In such cases an alternative grade to that calculated according to Annex A (normative) may be defined. When using reclaimed asphalt from mixtures in which a modified bitumen and/or modifier additive has been used, and/or the mixture itself contains a modified bitumen or an additive, the amount of reclaimed asphalt may be limited in documents related to the application of the product to a maximum of 10 % by mass of the total mixture. NOTE 1 The choice for this specification depends on the choice of requirements within this European Standard. For more performance designed mixes there might be no need to apply the pen and/or softening point rule. However, the pen or softening point rule is only valid for paving grade bitumen. NOTE 2 When applying a recipe approach to the mixture using a too great a proportion of modified bitumen or additive could lead to an incorrect decision in respect to the addition of the new binder. 4.3 Aggregate 4.3.1 Coarse aggregate Coarse aggregate shall conform to EN 13043 as appropriate for the intended use. 4.3.2 Fine aggregate Fine aggregate shall conform to EN 13043 as appropriate for the intended use. 4.3.3 All-in aggregates All-in aggregate shall conform to EN 13043 as appropriate for the intended use. 4.3.4 Added filler Filler aggregate shall conform to EN 13043 as appropriate for the intended use and may include materials such as cement, limestone and hydrated lime. Based on the experience in the place of use, the type and amount of added filler may be defined in documents related to the application of the product. NOTE The expression “as appropriate for the intended use” in 4.3.1 to 4.3.4 means that the selection of the requirements and the particular category depends on a number of conditions. These conditions include traffic density, climatic conditions, the construction of the course in which the mixture will be used, and economic considerations. 4.4 Reclaimed asphalt The use and the amount of reclaimed asphalt and the mix group, and/or the courses from which the reclaimed asphalt has been or will be derived may be defined in documents related to the application of the product.
