16、ommittee 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, at the latest by August 2011, and conflicting national standards shall be withdr
17、awn 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 or all such patent rights. This document supersedes EN 13074:2002. This Europea
18、n 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 13074-2, Bitumen and bituminous binders Recovery of binder from bituminous emulsion
19、or cut-back or fluxed bituminous binders - Part 2: Stabilisation after recovery by evaporation EN 13074-1 has been created as the result of the merging of EN 13074:2002 and EN 14895:2006 under a single EN 13074 reference (two different parts), since both standards describe similar procedures which a
20、re 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 specified more accurately. According to the CEN/CENELEC Internal Regulations, th
21、e 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, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Nether
22、lands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 13074-1:2011-05 EN 13074-1:2011 (E) 4 1 Scope This European Standard specifies a method for the recovery of binder from a bituminous emulsion or from a cut-back or fluxed bitumen a
23、fter conditioning at ambient temperature for 24 h followed by 24 h at 50 C, in such a way that will enable further testing with minimum changes of the binder characteristics. It applies to all types of bituminous emulsions, modified with polymers or non-modified, as well as to all types of cut-back
24、and fluxed bitumens, both modified with polymers and non-modified. For cut-back and fluxed bituminous binders, this test method is only an intermediate step and should be followed by the stabilisation procedure specified by EN 13074-2. Direct testing of the recovered binder is however used to evalua
25、te the setting ability of fluxed bituminous binders made with vegetal fluxes. NOTE The recovered binder is not necessarily identical to the initial binder. WARNING The use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the
26、 safety problems associated with its use. The hazards associated with 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
27、document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、 material remaining after the treatment of a bituminous emulsion or a cut-back or fluxed bitumen under the conditions specified according to this method 3.2 mineral flux flux which may be of carbochemical, petrochemical or petroleum origin or a mixture of those components DIN EN 13074-1:2011-05 EN 1
32、3074-1:2011 (E) 5 3.3 vegetal flux type of bio-flux derived exclusively from plant based (vegetal) product NOTE The previous two definitions correspond to the definitions mentioned in EN 15322 1 4 Principle A thin layer of a bituminous emulsion, cut-back or fluxed bituminous product is spread onto a
33、 suitable sheet of material. It is conditioned for 24 h in the laboratory at ambient temperature and then transferred into a ventilated oven for 24 h at 50 C. 5 Apparatus Usual laboratory apparatus and glassware, together with the following: 5.1 Flat plates, of known surface area, equipped with an e
34、dge 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 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 manufactur
35、ed from a suitable non-stick material, such as a silicone material, or may be coated with a non-stick coating 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
36、particular by giving the paper the exact dimensions of the bottom of the plates 5.2 Spatula, palette knife, or other suitable device for spreading the sample of emulsion or cut-back or fluxed bitumen. 5.3 Ventilated oven, at least 80 l internal volume, capable of maintaining a temperature of (50 2)
37、C around the sample and in which the level of the shelves has been checked. 5.4 Balance, of sufficient capacity, accurate to 0.001 kg. 6 Sampling Samples to be tested shall be taken in accordance with EN 58 and shall be prepared in accordance with EN 12594. 7 Procedure 7.1 Preparation of the test ho
38、lder Arrange the plate on a table (work surface) and check the level with a spirit level. 7.2 Bituminous emulsion 7.2.1 Determination of emulsion mass required 7.2.1.1 General Calculate the surface area of the plate (A) in m2. Where the binder content of the emulsion is not known, it will be necessa
39、ry to determine an accurate figure using the appropriate test (determined either by use of EN 1428 or EN 1431) DIN EN 13074-1:2011-05 EN 13074-1:2011 (E) 6 Calculate to the nearest gram the mass, M, of the emulsion sample required, and using the following calculations: 7.2.1.2 For emulsions with bin
40、der content higher or equal to 58% Residual emulsion binder required = (1,00 0,05) kg/m2 Mass of emulsion required (M), expressed in kg = 1,0 x 100/BAwhere A = Area of the plate, expressed in m2; B = Binder content expressed in %. When a proper evaporation of the emulsion cannot be achieved the quan
41、tity of residual emulsion binder required may be reduced up to 50 % of the value mentioned above (1,0 kg/m2). In this case, note that it is necessary to cover the whole surface of the mould with a thin film of emulsion to reach a good reproducibility on the test. This deviation has to be mentioned i
42、n the test report (Clause 8 d). 7.2.1.3 For emulsions with binder content lower than 58% Emulsion Application = (1,00 0,05) kg/m2Mass of emulsion required (M), expressed in kg = 1,0 x A where A = Area of the plate, expressed in m2; When a proper evaporation of the emulsion cannot be achieved the qua
43、ntity of emulsion required may be reduced up to 50 % of the value mentioned above (1,0 kg/m2). In this case, note that it is necessary to cover the whole surface of the mould with a thin film of emulsion to reach a good reproducibility on the test. This deviation has to be mentioned in the test repo
44、rt (Clause 8 d). 7.2.2 Recovery procedure Place the plate(s) on the balance and weigh the mass of required emulsion calculated in 7.2.1 Using a spatula (5.2) evenly spread the amount of emulsion. Place the plate(s) containing the emulsion layer on a flat, even surface. Check the levelness of the pla
45、te(s) using a spirit level and condition the plate(s) for (24 1) h at (23 5) C, under normal laboratory conditions. NOTE Care should be taken not to store plates in a dusty environment in order to avoid entrainment of dust into the sample(s) during this process. Transfer the plate(s) to the pre-heat
46、ed oven (5.3) and leave for (24 1) h at (50 2) C. In case more than one plate is used, 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. If, how
47、ever, the recovered sample is required for stabilisation, proceed as specified in EN 13074-2. DIN EN 13074-1:2011-05 EN 13074-1:2011 (E) 7 7.2.3 Removal and storage of the recovered binder Collect without any delay the recovered binder from the plate(s) using an appropriate tool but without applying
48、 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 freezer. The recovered binder from all the plates of the same sample shall be placed in a same sample container. If the recovered 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 stor
