EN 13108-3:2016 (E) 6 Introduction The aim of this European Standard is to enable specification of Soft Asphalt 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 13108-3 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 Soft Asphalt and the use of the pavement and to avoid a combination of potentially conflicting requirements. SIST EN 13108-3:2016
EN 13108-3:2016 (E) 7 1 Scope This European Standard specifies requirements for mixtures of the mix group Soft Asphalt for use on low volume roads and roads with low stability. Soft Asphalt is used for surface courses, regulating courses and bases in colder climates. The mixtures of the mix group Soft Asphalt are produced on the basis of hot bitumen. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by this standard. 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.

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 and shall conform to EN 12591. Premix binders and other bituminous binders that are not covered by EN 12591 can be used provided that information is given as stated in 4.1, and that the base bitumen is conforming to EN 12591. 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 bitumen may be defined in documents related to the application of the product. The bitumen shall be selected from the grades between 250/330 and 650/900 or between V1500 and V12000 inclusively. When an additive is used to lower the production temperature of the Soft Asphalt and thereby changes relevant properties of the binder at temperatures representative for the climatic conditions in the place SIST EN 13108-3:2016
EN 13108-3:2016 (E) 11 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. 4.2.2.2 Mixtures with reclaimed asphalt When using more than 10 % by mass of the total mixture of reclaimed asphalt from mixtures in which mainly 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 selected, the following requirement may be defined in documents related to the application of the product. The viscosity and/or the softening point and/or the penetration of the binder in the resulting mixture, calculated from the viscosity and/or the softening point and or the penetration of the added binder and the recovered binder from the reclaimed asphalt, shall meet the viscosity and/or softening point and/or penetration requirements of the specified grade. The calculation shall be performed according to Annex A (normative). 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. NOTE The choice for this specification depends on the choice of requirements with in this European Standard. For more performance designed mixes there might be no need to apply the viscosity requirement and/or softening point rule. However, the viscosity requirement or softening point rule is only valid for paving grade bitumen. 4.3 Aggregates 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 Added filler 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. The properties of reclaimed asphalt declared in accordance with EN 13108-8 shall conform to requirements that may be selected appropriate for the intended use. SIST EN 13108-3:2016
EN 13108-3:2016 (E) 12 NOTE The expression “appropriate for the intended use” 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. The upper sieve size D of the aggregate in the reclaimed asphalt shall not exceed the upper sieve size D of the mixture. The aggregate properties of the reclaimed asphalt or of the mixed aggregates from the reclaimed asphalt with the other aggregates shall fulfil the requirements for aggregate defined in documents related to the application of the mixture. When required, the amount of reclaimed asphalt, the mix group and/or the courses from which the reclaimed asphalt has been or will be derived shall be declared in the Type Test report. 4.5 Additives The nature and properties of all additives shall be declared and they shall conform to the requirements referred to in 4.1. For specific applications and based on the experience in the place of use the amount of additives may be defined in documents related to the application of the product. NOTE Chemical and organic additives can be used for example, to reduce production temperatures by influencing the viscosity of the binder. This might have an effect on other relevant mixture properties. 5 Requirements for the mixture 5.1 General The mix formulation shall be declared in the Type Test report according to EN 13108-20, including: — the target percentages passing the specified sieves; the target grading shall be declared for the sieves called up in Tables 1 to 10 where appropriate; — the target binder content and where relevant, the binder content from reclaimed asphalt; —
