BS EN 12697-2:2015EN 12697-2:2015 (E) 7 1 Scope This European Standard specifies a procedure for the determination of the particle size distribution of the aggregates of bituminous mixtu
37、res by sieving. The test is applicable to aggregates recovered after binder extraction in accordance with EN 12697-1 or EN 12697-39. The applicability of this European Standard is described in the product standards for bituminous mixtures. NOTE Fibres, solid (non-soluble during extraction) additives
38、 and (some) binder modifiers influence the test result. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

42、ative percentages by mass passing those sieves 3.2 D upper sieve size of the aggregate in the bituminous mixture in millimetre (mm) according to the relevant material specification standard 4 Significance and use The composition of a bituminous mixture in terms of binder content and aggregates gradi
43、ng is a significant quality parameter. The European Standard for bituminous mixtures contains some grading specifications. Controlling the mixture grading is an important instrument for product quality management. BS EN 12697-2:2015EN 12697-2:2015 (E) 8 5 Principle The test consists of the determina
44、tion of the particle size distribution of the aggregates in the bituminous mixture by sieving and weighing. A granulometric analysis of the aggregate is performed after binder extraction. 6 Apparatus 6.1 Unless stated otherwise, the apparatus as required in EN 933-1 shall be used. 6.2 Sieves with ap
45、erture size up to and including 2,8 mm shall be in accordance with ISO 3310-1. 6.3 Sieves with aperture size of 4 mm and larger shall be in accordance ISO 3310-2. 7 Sample preparation The test shall be carried out on the material recovered after completion of the test as specified in EN 12697-1 or E
46、N 12697-39. It should be ensured visually that all aggregate is recovered from the mixture and that no binder remained adhering. The recovered aggregate shall be dried to constant mass. Particles shall be separated completely. NOTE 1 “Constant mass” is defined as successive weighings after drying at
47、 least 1 h apart not differing by more than 0,1 %. NOTE 2 Other regimes for achieving constant mass can be used provided that they can demonstrate that they give the same results as drying at (110 5) C. 8 Procedure The test shall be carried out on the aggregate according to EN 933-1. When less mater
48、ial to be tested is available than required in this European Standard, the total amount of material available shall be tested. However the minimum amount of material shall be the lesser of 50 D g and 1 000 g. When the aggregate is visually greasy after carrying out the test in accordance with EN 12697-1, a decrement of the surface tension may be required by adding some peptizing additive. When this test is carried out after a binder extraction procedure in which a sieving stage is incorporated containing the applicable sieves, and when th
