DIN EN 13108-8:2016-12 EN 13108-8:2016 (E) 5 Introduction The use of recycling in asphalt production makes it necessary to specif
26、y reclaimed asphalt as a constituent material in a way similar to that of aggregates and binders. In the asphalt product standards EN 13108-1 up to and including EN 13108-7 and EN 13108-9 the use of reclaimed asphalt is permitted with requirements related to the percentage addition. Site-won asphalt
27、 comprises asphalt taken by milling of asphalt road layers, slabs ripped up from asphalt pavements and asphalt from reject and surplus production. The processing of site-won asphalt results in reclaimed asphalt, suitable and ready to be used as constituent material for asphalt, after being tested, a
28、ssessed and classified according to this standard. Reclaimed asphalt (RA) may be used as a constituent material for bituminous mixtures manufactured in an asphalt plant, in accordance with the specifications for those mixtures. This European Standard contains requirements for reclaimed asphalt with
29、respect to binder and aggregate properties and foreign matter that apply in all cases of usage of reclaimed asphalt. Additionally, this European Standard indicates which properties of the reclaimed asphalt and its constituent materials need to be declared and documented if a description of a feedsto
30、ck is necessary. Since the requirements for the asphalt mixtures are the same for mixtures with and without reclaimed asphalt, a set of properties of the reclaimed asphalt are of importance. The particle size and properties of the aggregate, the binder content, the properties of the binder and forei
31、gn matter in the reclaimed asphalt are relevant to the quality of the product, i.e. the fresh asphalt in which it is mixed. The level of homogeneity of the material in practice determines the maximum amount of reclaimed asphalt that may be used. The size of the particles of asphalt in the reclaimed
32、asphalt, which may range from large lumps to finely milled material, is relevant only to the process to be used to mix into the fresh asphalt. DIN EN 13108-8:2016-12 EN 13108-8:2016 (E) 6 1 Scope This European Standard specifies requirements for the classification and description of reclaimed asphal
33、t as a constituent material for asphalt mixtures. It is not a standard for compliance. This European Standard only specifies reclaimed asphalt with bituminous binders, such as: paving grade bitumen, modified bitumen or hard grade bitumen. Reclaimed asphalt contaminated with coal tar or other additiv
34、es or components above hazardous levels is not covered by this standard and will need to be considered under Member State Environmental, and Health and Safety Regulations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispe

40、nd fine aggregates, filler aggregate and bituminous binder which is used in the construction of a pavement DIN EN 13108-8:2016-12 EN 13108-8:2016 (E) 7 Note 1 to entry: The asphalt may include one or more additives to enhance the initial laying characteristics, performance or appearance of the mixtu
41、re, but it is often not possible to identify and differentiate all specific additives in site-won asphalt. 3.1.2 site-won asphalt the material to be recycled, in the form of milled asphalt road layers or as slabs ripped up from asphalt pavements, or being asphalt from reject, surplus or failing prod
42、uction Note 1 to entry: These materials will require assessment and often processing before being suitable as a constituent material. 3.1.3 reclaimed asphalt RA the processed site-won asphalt, suitable and ready to be used as constituent material for asphalt, after being tested, assessed and classif
43、ied according to this standard Note 1 to entry: Processing can include one or more of: milling, crushing, sieving (screening), blending, etc. 3.1.4 feedstock of reclaimed asphalt quantity of reclaimed asphalt (according to 3.1.3) with classified / declared properties, suitable and ready to be used a
44、s constituent material for the manufacturing of asphalt mixtures, being either: reclaimed asphalt used for a special purpose or reclaimed asphalt from special asphalt mixtures with specific properties (e.g. PSV, aggregate type, etc.); or reclaimed asphalt in a stockpile which is added to and used of
45、, on a regular basis, as long as the requirements of Clause 5 and properties of the final asphalt mixture are observed Note 1 to entry: The latter is also called the “general” feedstock, while the former may need additional description by the manufacturer. Note 2 to entry: When the properties of the
46、 reclaimed asphalt in the general feedstock change to such an extent that the reclaimed asphalt as constituent material is not conforming to the reclaimed asphalt as documented in the Type Test, EN 1310820 requires a new Type Test. Note 3 to entry: Feedstocks will have been assessed and they consist
47、 only of reclaimed asphalt according to 3.1.3. 3.1.5 aggregate size designation of the size of the aggregate in the reclaimed asphalt in terms of lower (d) and upper (D) sieve sizes, expressed as d/D Note 1 to entry: For reclaimed asphalt, d will almost invariably be 0. 3.1.6 particle size of reclai
