This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety an

For dated references, only the edition cited
26、applies. For undated references, the latest edition of the referenced document (including any amendments) applies.EN 58, Bitumen and bituminous binders Sampling bituminous bindersEN 12594, Bitumen and bituminous binders Preparation of test samples3 PrincipleA homogeneous sample of modified bitumen i
27、s maintained in a vertical vessel at 180 C, or at a temperature specified by the producer, for 3 days. After the sample has cooled down, it is cut into three equal parts. The two ends (top and bottom) are analysed further to evaluate possible differences in characteristics.If the chosen temperature
28、differs from 180 C, it shall be mentioned in the test report.4 ApparatusUsual laboratory apparatus and glassware, together with the following:4.1 Tube, of thin unvarnished aluminium, of height 160 mm minimum and of diameter between 25 mm and 40 mm, closed at one end (bottom end) and typically “tooth
29、paste tube”.4.2 Oven, maintained at a temperature of (180 5) C or other chosen test temperature 5 C for three consecutive days.4.3 Tins, one to be marked “top” and one to be marked “bottom” (see 5.5), each of sufficient capacity to contain the combined upper and lower parts of different tubes.4.4 Fo
30、rceps or pliers, of steel, (e.g. forceps: straight and of length 200 mm - 250 mm), for closing the aluminium tube filled with sample.4.5 Cutting tool, a broad-bladed knife or sharpened filling knife, for cutting the aluminium tube containing the sample at a low temperature.4.6 Heating tool, gas flam
31、e, heating plate or similar for heating the cutting tool5BS EN 13399:2017EN 13399:2017 (E)5 Procedure5.1 GeneralEnsure that the laboratory sample is representative of the modified bitumen to be analysed, in accordance with EN 58. Ensure that the laboratory sample is homogeneous and non-contaminated.
32、Sufficient test sample shall be prepared in accordance with EN 12594, placed in a suitable container.If large quantities of sample are needed for characterization, multiple tubes shall be conditioned simultaneously.NOTE Examples of characterization tests: softening point EN 1427 1; needle penetratio
33、n, EN 1426 2; complex modulus, EN 14770 3 and elastic recovery EN 13398 4.5.2 Filling of the tubeDraw a marking line on the tube for the maximum filling height (100 mm to 120 mm). Then mark the lines showing were to cut the top and bottom sections. The tube shall be cut into three equal parts from t
34、he maximum filling height.Pour the homogeneous liquid sample into the tube to the filling mark, taking care to avoid incorporation of air bubbles.NOTE Correct filling height of material can be checked by weighing the filled tube.A possibility for thermal expansion of the test material is necessary,
35、and is created by squeezing the tube jacket slightly flat after filling.5.3 Closing of the tubeEnsure that the filled tube is tightly closed, to avoid any action of air during high-temperature storage.After pouring the test material into the tube, press the open end of the tube at a short distance a
36、bove the binder surface. Carefully close the tube and seal, using forceps. Ensure that no air remains by squeezing test material up along the interior part of the tube. Press the tube end flat and fold the tube end tightly at least two times using forceps.5.4 Test conditionsWithin 1 h after filling,
37、 place the tube in the preheated oven in a vertical position.NOTE The separation tendency can be affected if the sample is allowed to cool down before the storage test.Ensure that the tube is maintained in a vertical position at the chosen temperature with an accuracy of 5 C for (72 1) h.5.5 Recover
38、y of the sampleRemove the tube from the oven and let it cool down to room temperature, still in the same vertical position. One of the following techniques are used for the recovery of the sample:1. CuttingPlace the cooled tube horizontally on a hard, flat and clean surface, and cut into three equal
39、 parts with a sharp, heated cutting tool.2. Peeling6 BS EN 13399:2017EN 13399:2017 (E)Remove the aluminium foil from the cooled tube with suitable pliers. Place the cylindrical sample horizontally on a hard, flat and clean surface, and cut it into three equal parts with a heated cutting tool.NOTE To
40、 facilitate the cutting of the tube or the removal of aluminium foil, the tube can be given a second cooling step, e.g. for 30 min at 20 C in a freezer.The middle part is of no use and is discarded. Place the top and bottom parts separately in the respective tins marked “top” and “bottom”. Melting t
41、emperature is (180 5) C, or a temperature specified by the producer 5 C. After no longer than 60 min in the oven, remove the aluminium pieces from the cutting procedure. Then homogenise the samples before moulding.The parts are now ready for further testing.If more than one tube is needed, combine a
42、nd homogenize according to EN 12594, before moulding.6 Test reportThe test report shall contain at least the following information:a) type and identification of the sample under test;b) reference to this European Standard;c) measured values for the top and the bottom part including reference to the
43、test method. Difference or ratio in their values whichever appropriate, according to the used European standards;d) storage temperature, if it differs from 180 C;e) any deviation, by agreement or otherwise, from the procedure specified;f) date of the test.7BS EN 13399:2017EN 13399:2017 (E)Bibliograp
