14、ods (ISO 3696:1987) 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 fines mixing time time in seconds for the mixability of a mixture of mineral filler and bitumen emulsion without noticeable breaking effect under the conditions specified in
15、this standard 4 Principle A specified quantity of filler is added at a uniform rate, with stirring, to a specified quantity of bitumen emulsion diluted with water. Stirring is continued until the mixture becomes pasty and forms lumps which do not adhere to the walls of the pan. This, combined with a
16、 noticeable increase in stirring power indicates the end of mixability. The time to reach this point (breaking status) is the fines mixing time. 5 Reagents and materials Use only reagents of recognized analytical grade and water conforming to grade 3 of EN ISO 3696. 5.1 Reference filler The Sikaisol
17、 filler1 (characteristics are given in Annex A) shall be used as the reference filler. Other filler such as the Forshammer filler may be used as an alternative to the Sikaisol filler. In the event of dispute, the Sikaisol filler shall be used. 5.2 Cleaning agents, as used conventionally in laborator
18、ies. 1 This information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of the product name. Equivalent products may be used if they can be shown to lead to the same results, or if a correlation between the products has been established.
19、EN 13075-2:2009 (E) 5 6 Apparatus Usual laboratory apparatus and glassware, together with the following. 6.1 Oven, capable of being maintained at (110 5) C. 6.2 Conical shaped funnel of suitable volume, capable of feeding the filler at a rate of 10 g per 5 s. 6.3 Spatula, nickel or stainless steel,
20、20 cm long. 6.4 Spatula, spoon shaped for adding filler. 6.5 Stop watch, with an accuracy of 0,2 s or better over a time interval of 500 s. 6.6 Bottles, of approximate capacity 500 ml made of a material that will not react with the emulsion, having tight fitting lids, for storing emulsion samples an
21、d water. 6.7 Constant temperature bath and/or climatic chamber, capable of a temperature of (25 1) C. NOTE If the bath is used to condition the emulsion sample bottles, it should be equipped with a frame or device to prevent the bottles from moving in the water bath. 6.8 Balance, capable of weighing
22、 up to 1 000 g with an accuracy of 0,1 g or better. 6.9 Enamelled or stainless steel dish, of suitable volume, capable of containing 150 g of diluted emulsion and 150 g of filler. 6.10 Thermometer, having a suitable range, capable of measuring the temperature to the nearest 0,2 C. 7 Sampling The tes
23、t material shall be sampled in accordance with EN 58 and shall be prepared in accordance with EN 12594. 8 Procedure Carry out the procedure under normal laboratory conditions (18 C to 28 C). Dry the quantities of filler, required for the test, in the oven (6.1) at a temperature of (110 5) C until co
24、nstant mass is reached and let it cool to ambient temperature in a dessiccator. Pour a portion of emulsion (250 10) g and water (150 10) g into bottles (6.6) and secure the lid. Place the required quantity of filler in a closed container. Place the bottles with the emulsion and the water and the con
25、tainer with the filler in the constant temperature bath or climatic chamber (6.7) for a minimum of 1,5 h. Transfer (100 0,5) g of the emulsion in the dish (6.9) then add (50 0,5) g of water while agitating with the spatula (6.3). Transfer (150 1) g of filler in the conical shaped funnel (6.2). Start
26、 the stop watch (6.5), and while mixing with the spatula (6.3) at constant rate of 1 r/s, add filler contained in the conical shaped funnel (6.2) to the diluted emulsion, by portions of 10 g per 5 s, so that within the 75 s, the overall (150 1) g filler is poured. Continue mixing and measure the tim
27、e until the emulsion breaks (see Clause 4). EN 13075-2:2009 (E) 6 If the bitumen emulsion does not break within 300 s, the test procedure shall be stopped, and the result of the test “ 300 s“ shall be reported. NOTE It may happen that lumps form as soon as the filler contacts the diluted emulsion, b
28、ut the body of the emulsion neither breaks nor reaches the “pasty” stage within 300s In such cases, the emulsion is deemed to have not broken. The test procedure shall be stopped and the result of the test “ 300 s formation of lumps” shall be reported. Repeat the test with a new test portion taken f
29、rom the same laboratory sample using clean apparatus. 9 Expression of results Express the individual mixing time values (in seconds) to the nearest integer. Express the result as the arithmetic mean of the two individual results of mixing time, to the nearest integer. 10 Precision NOTE A European ro
30、und robin test has not been carried out. The precision data given are based on data obtained by long term experience in Germany and calculated according to ISO 5725 1. They are considered valid until the results of a European round robin test become available. 10.1 Repeatability The difference betwe
31、en two successive test results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, exceed 10 % of the average value in only one case in twenty. 10.2 Repro
32、ducibility The difference between two single and independent results obtained by different operators working in different laboratories on identical test material would, in the long run, in the normal and correct operation of the test method, exceed 20 % of the average value in only one case in twent
33、y. 11 Test report The test report shall contain at least the following information: a) type and complete identification of the sample under test; b) reference to this European Standard; c) reference to the used filler; d) result of the test and individual mixing time values (see Clause 8 and Clause
34、9); e) any deviation, by agreement or otherwise, from the procedure described; f) date of the test. EN 13075-2:2009 (E) 7 Annex A (normative) Characteristics of the Sikaisol filler The Sikaisol filler shall have at least the following properties: Natural fine silica, uncrushed; SiO2 content greater
