14、ant technical change with respect to EN 13179-1:2000: Clause 7 has been completed by the following sentence: “For some types of filler, the stiffening effectmay make the mixture of filler and bitumen so stiff that a homogeneous mixture cannot be obtained bystirring for the specified time. If a homog

22、 EN 12591, Bitumen and bituminous binders Specifications for paving grade bitumens 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 delta ring and ball increase of the softening point of a bitumen/filler aggregate mixture in a composition of 3

23、7,5 volumeparts of filler aggregate and 62,5 volume parts of bitumen, related to the softening point of the bitumenused in that mixture 3.2 constant mass mass determined by successive weighings performed at least 1 h apart and not differing by more than0,1 % Note 1 to entry: In many cases constant m

24、ass can be achieved after a test portion has been dried for a pre-determined period in a specified oven at (110 5) C. Test laboratories can determine the time required toachieve constant mass for specific types and sizes of sample dependent upon the drying capacity of the ovenused. 3.3 laboratory sa

25、mple reduced sample derived from a bulk sample for laboratory testing 3.4 test portion sample used as a whole in a single test BS EN 13179-1:2013 EN 13179-1:2013 (E) 5 3.5 softening point temperature at which the material under standardized test conditions attains a certain consistencybetween solid

26、and liquid behaviour 4 Principle The test is carried out using filler aggregate particles smaller than 0,125 mm and bitumen. Duplicatedisks of bitumen and a bitumen/filler aggregate mixture are cast in brass rings. The rings are heatedat a controlled rate in a water bath while supporting a steel bal

27、l and the temperature at which thedisks soften enough to allow the steel ball to fall a distance of (25,0 0,4) mm is determined. Themean values of temperature for the rings containing the bitumen and the rings containing thebitumen/filler aggregate mixture are calculated. The difference between the

28、two mean temperatures isreported as R mfis the mass of added filler aggregate, in grams; fis the particle density of the filler aggregate, in megagrams per cubic metre;bis the density of the paving bitumen at 25 C, in megagrams per cubic metre. NOTE 1 This gives a mixture by volume of 37,5 % filler

29、aggregate and 62,5 % bitumen. NOTE 2 If bis not known, 1,025 Mg/m3can be used in the calculation. Put the dish back into the flask heater and stir the filler aggregate into the bitumen over a period of(150 5) s. Continue to stir for a further (150 5) s with the temperature held at (150 5) C, so that

30、 ahomogenous mixture is obtained. BS EN 13179-1:2013 EN 13179-1:2013 (E) 7 Place the other two brass rings on the plate coated with release agent and slightly overfill them withthe mixture of bitumen and filler aggregate. Determine the softening points of the bitumen and the bitumen/filler aggregate

31、 mixture as specified inEN 1427. For each part of the test use one brass ring filled with the bitumen and one brass ring filledwith the bitumen/filler aggregate mixture. For factory production control purposes both rings of the same type may be tested together. Theprocedure in Clause 7 should be use

32、d in cases of dispute. Repeat the whole test if the difference between the two temperatures for the softening point of thebitumen and/or the difference between the two temperatures for the softening point of thebitumen/filler aggregate mixture exceeds 3 C. 8 Calculation and expression of results Cal

33、culate the mean of the two temperatures of the softening points of the bitumen and thebitumen/filler aggregate mixture in 0,1 C. Calculate the difference between the two means andexpress the value to the nearest 0,5 C. Report the rounded result as R b) the stiffening effect of the filler aggregate,

34、expressed as R c) the name of the brand of the filler aggregate; d) the date of test; e) any variations to the test procedure. 9.2 Optional data The test report can include the following information: a) name and location of sample source; b) a description of the material; c) a description of the sam

35、pling procedure; d) the individual data of the temperatures of all softening points.
