35、 European Standard describes a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasiveness of porous asphalt. The test ap
36、plies to laboratory compacted porous asphalt mixtures the upper sieve size of which does not exceed 25 mm. It does not reflect the abrasive effect by studded tyres. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These nor

41、machine, as specified in EN 1097-2. 3.2 Thermometer, capable of covering the test temperature range with an accuracy of 0,5 C. 3.3 Chamber, room or enclosure, large enough for the Los-Angeles-machine. During the test, the air temperature in the chamber shall remain constant to the test temperature 2
42、 C. The air temperature shall be measured near the Los-Angeles-machine. 3.4 Oven, equipped with a closed ventilation system or a chamber fitted with a thermostatic control to maintain the test temperature constant in vicinity to the samples, stored prior to the test, to 1 C. 3.5 Balances, of suitabl
43、e capacity for the mass to be weighed with an accuracy of 0,1 g. 4 Preparation of test specimen 4.1 At least five specimens shall be prepared for each sample tested. Licensed Copy: Wang Bin, na, Tue Oct 23 07:29:44 GMT+00:00 2007, Uncontrolled Copy, (c) BSIEN 12697-17:2004+A1:2007 (E) 7 4.2 The cyli
44、ndrical specimens shall have a diameter of (100 3) mm and a height of (63,5 5,0) mm. !The asphalt shall be mixed in accordance with EN 12697-35:2004+A1 and specimens compacted“ as specified in !EN 12697-30:2004+A1“, compacted by 2 50 blows, or EN 12697-31, compacted by 40 gyrations. NOTE The compact
45、ion method has an influence on the result. 4.3 After the specimens have been compacted and removed from the mould, their density and void content, if required, shall be determined in accordance with !EN 12697-6:2003+A1“ (Procedure D: bulk density by dimensions) and EN 12697-8. 4.4 Prior to testing,
46、the specimens shall be stored on a flat surface for at least 2 days at a temperature of not more than 25 C. 5 Procedure 5.1 The test temperature shall be defined and maintained in the chamber during the test with an uncertainty of 2 C. Before testing, specimens shall be kept at the test temperature
47、for at least 4 h. NOTE Test temperature has a very large influence on the test result. Temperatures between 15 C and 25 C are usually used for design purposes. For porous asphalt in cold climate zones, temperatures representing the low temperature local conditions can also be used. The test is not a
48、dequate for temperatures above 35 C. 5.2 The mass of specimen shall be determined and W1(see clause 6) shall be recorded. One specimen shall then be placed inside the Los-Angeles-machine drum and, with the metal balls removed, the drum shall be turned at 3,1 rad/s to 3,5 rad/s (30 rpm to 33 rpm) for
49、 300 turns. 5.3 When the test is completed, the specimen shall be removed from the machine, slightly cleaned by means of a cloth eliminating particles that are clearly loose, and weighed again. The reading W2(see clause 6) shall be recorded. 5.4 The test shall be repeated in the same way for each of the specimens prepared according to clause 4. NOTE Observation as to whet
