23、lled Copy, (c) BSIBS EN 13074-1:2011EN 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 after conditioning at ambient temperature for 24 h followed by 24 h at 50 C, in such a way that will

24、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 and fluxed bitumens, both modified with polymers and non-modified. For cut-back and fluxed bituminou

25、s 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 evaluate the setting ability of fluxed bituminous binders made with vegetal fluxes. NOTE The recovered bin

26、der 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 safety problems associated with its use. The hazards associated with the use of this method have be

However it is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of reg

33、: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 suita

34、ble 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 edge of

35、 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 manufactured fro

36、m 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 partic

37、ular 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) C arou

38、nd 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 holder A

39、rrange 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 necessary to

40、determine an accurate figure using the appropriate test (determined either by use of EN 1428 or EN 1431) Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 05/08/2011 07:49, Uncontrolled Copy, (c) BSIBS EN 13074-1:2011EN 13074-1:2011 (E) 6 Calculate to the nearest gram the mass, M, of the emulsi

41、on sample required, and using the following calculations: 7.2.1.2 For emulsions with binder 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 conte

42、nt expressed in %. When a proper evaporation of the emulsion cannot be achieved the quantity 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 em

43、ulsion to reach a good reproducibility on the test. This deviation has to be mentioned in 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 plat

44、e, expressed in m2; When a proper evaporation of the emulsion cannot be achieved the quantity 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

45、 a good reproducibility on the test. This deviation has to be mentioned in the test report (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(

46、s) containing the emulsion layer on a flat, even surface. Check the levelness of the plate(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 entrainme

47、nt of dust into the sample(s) during this process. Transfer the plate(s) to the pre-heated 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 ea

48、ch plate. At the end of the specified period, remove the plate(s) from the oven. If, however, the recovered sample is required for stabilisation, proceed as specified in EN 13074-2.

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 test
