16、 (E) 3 Foreword This document (EN 13074-2:2011) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement,
17、at the latest by August 2011, and conflicting national standards shall be withdrawn at the latest by August 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any
18、 or all such patent rights. This document supersedes EN 14895:2006. This European Standard EN 13074 consists of the following parts: EN 13074 -1, Bitumen and bituminous binders Recovery of binder from bituminous emulsion or cut-back or fluxed bituminous binders Part 1: Recovery by evaporation EN 130
19、74 -2, Bitumen and bituminous binders Recovery of binder from bituminous emulsion or cut-back or fluxed bituminous binders Part 2: Stabilisation after recovery by evaporation EN 13074-2 has been created as the result of the merging of EN 13074:2002 and EN 14895:2006 under a single EN 13074 reference
20、 (two different parts), since both standards describe similar procedures which are generally performed consecutively. The two different parts have been made as consistent as possible and the procedures for removing, storing and preparing the binder sample for further testing have been clarified and
21、specified more accurately. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece
22、, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 13074-2:2011-05 EN 13074-2:2011 (E) 4 1 Scope This European Standard specifies a method for the stab
23、ilisation at 85 C for 24 h of a binder after recovery from a bituminous emulsion or from a cut-back or fluxed bitumen for further testing. It applies to all types of bituminous emulsions, modified with polymers or non-modified, and as well as to all types of cut-back and fluxed bitumens, both modifi
24、ed with polymers and non-modified. The recovery test method is specified in EN 13074-1. WARNING The use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. The hazards associated wit
25、h the use of this method have been assessed using cut-back bitumen containing 10 % kerosene and 90 % 160/220 penetration grade bitumen and were found low enough to be acceptable. However it is the responsibility of the user of this document to establish appropriate safety and health practices and de
26、termine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced docum
27、ent (including any amendments) applies. EN 12594, Bitumen and bituminous binders Preparation of test samples EN 13074-1, Bitumen and bituminous binders Recovery of binder from bituminous emulsion or cut-back or fluxed bituminous binders Part 1: Recovery by evaporation 3 Terms and definitions For the
28、 purposes of this document, the following terms and definitions apply. 3.1 recovered binder material remaining after the treatment of a bituminous emulsion or a cut-back or fluxed bitumen under the conditions specified in EN 13074-1 3.2 stabilised binder binder free from most of the volatile part of
29、 its flux oils, obtained from recovered binder by heating at 85 C for 24 h under the conditions specified according to this method 4 Principle A thin layer of recovered binder from a bituminous emulsion or a cut-back or fluxed bituminous product is stabilised for 24 h at 85 C in a ventilated oven. 5
30、 Apparatus Usual laboratory apparatus and glassware, together with the following: 5.1 Flat plates, of known surface area, equipped with an edge of maximum internal height 35 mm and a minimum surface area of 0.04 m. The internal base of the plate shall have no deformation greater in depth DIN EN 1307
31、4-2:2011-05 EN 13074-2:2011 (E) 5 than 1 mm. The number of plates to be used shall be appropriate to give a sufficient amount of binder for further testing. The plates may be manufactured from a suitable non-stick material, such as a silicone material, or may be coated with a non-stick coating such
32、as such as silicone coating; or the plates may be lined with a suitable non stick paper or fabric. When using non-stick paper or fabric, any crinkle of the paper or fabric shall be avoided, in particular by giving the paper the exact dimensions of the bottom of the plates. 5.2 Ventilated oven, at le
33、ast 80 l internal volume, capable of maintaining a temperature of (85 2) C around the sample and in which the level of the shelves has been checked. It is acceptable to use the same oven for both the recovery step (EN 13074-1) and the stabilisation step provided that this oven is capable of maintain
34、ing around the sample the specified temperatures. In case the same oven is to be used for both steps, the sample may be left in the oven during the period of temperature adjustment (from 50 C as specified in EN 13074-1 up to 85 C), provided this period does not exceed 1 h. 6 Procedure 6.1 Stabilisat
35、ion of the binder Stabilisation of the recovered binder shall take place immediately after the recovery procedure (EN 13074-1). Put the plate with the recovered binder in the oven (5.2) and leave it for (24 1) h at (85 2) C. If there are several plates, introduce them simultaneously. The binders sho
36、uld not be grouped when their volatile parts might be of different natures. Arrange the plates in such a way that air circulation is not hindered. Air circulation has to be effective on each side of each plate. At the end of the specified period, remove the plate(s) from the oven. 6.2 Removal and st
37、orage of the stabilised binder Collect without any delay the stabilised binder from the plate(s) using an appropriate tool but without applying any extra heat to the sample. To facilitate the removal of binders from the non-stick material, it may be necessary to cool the plates in a refrigerator or
38、freezer. The stabilised binder from all the plates of the same sample shall be placed in a same sample container. If the stabilised binder is required for further testing at a later date, it shall be stored for as short a time as possible, but no longer than 28 days, in a sealed container and stored
39、 at a temperature lower than 28 C. NOTE When storing the stabilised binder, a period as short as possible should be favoured (if possible less than one week). Specific storage conditions (use of inert gas, e.g. nitrogen) are recommended, especially in cases where storage time exceeds 1 week. 6.3 Hom
40、ogenisation of the stabilised binder and preparation of the sample for further testing Before performing further testing on the stabilised binder, the binder from each plate shall be homogenized by mixing. If the sample of recovered binder comes from more than one plate, the binder from the whole pl
41、ates shall be blended. Heating of the stabilised binder shall be strictly in accordance with EN 12594. When possible, the preparations for further testing shall be carried out immediately after homogenising the stabilised binder to avoid reheating. When moulding samples for further testing and in or
42、der to prevent any further ageing, the stabilised binder shall be heated at a temperature between expected softening point + 80 C and expected softening point + 100 C for the minimum time necessary. Moulds for further testing shall be preheated according to the recommendations mentioned in the appro
43、priate standards. DIN EN 13074-2:2011-05 EN 13074-2:2011 (E) 6 7 Test report The test report shall contain at least the following information: a) type and complete identification (including the date and place of sampling) of the material under the recovery test (EN 13074-1) followed by the stabilisa
44、tion test; b) reference to this European Standard; c) conditions of use of the stabilised binder (see 6.2 and 6.3); d) any deviation, by agreement or otherwise, from the procedure described; e) date of the test.
