SIST EN 13108-4:2016



EN 13108-4:2016 (E) 6 Introduction The aim of this European Standard is to specify bituminous mixtures on a performance level. Specifications for Hot Rolled Asphalt have traditionally been based on compositional recipes combined with specifications for the constituent materials with additional requirements based on tests on the product. Although more tests are available to provide information on the performance of the material, they are still insufficient to cover the actual performance of the material in the road. Therefore a combination with composition and specifications for the constituent materials will still be necessary. This European Standard covers a large variety of materials for different applications, traffic and climate conditions. EN 13108-4 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 13108-4:2016



EN 13108-4:2016 (E) 7 1 Scope This European Standard specifies requirements for mixtures of the mix group Hot Rolled Asphalt for use on roads, airfields and other trafficked areas. Hot Rolled Asphalt is used for surface courses, binder courses, regulating courses and bases. The mixtures of the mix group Hot Rolled 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.

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 hard paving grade 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, the hard grade bitumen to EN 13924-1 and the multigrade bitumen to EN 13924-2. When natural asphalt is used, it shall conform to Annex B. Premixed bituminous binders that are not covered by the standards EN 12591, EN 14023 or EN 13924-1 and EN 13924-2 may be used provided that information is given as stated in 4.1, and that the base bitumen is conforming to EN 12591, EN 14023 or EN 13924-1 and 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 bitumen and the amount and category of natural asphalt may be defined in documents related to the application of the product.

In case of a paving grade bitumen the grade shall be selected from the grades between 30/45 and 100/150 inclusively. 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 Hot Rolled Asphalt 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. 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 selected, the following requirements may be def
