4、tish Standard is the official English language version of EN 13179-2:2000, which is included in a package of new European Standards being prepared by CEN/TC 154 relating to aggregates. Although the English language versions of these European Standards will be adopted as British Standards as they bec
5、ome available, the existing British Standards for aggregates will be retained, but only until such time that the completed package of European Standards become available. The original group of British Standards will then be withdrawn and this will be noted in Update Standards The UK participation in
6、 its preparation was entrusted by Technical Committee B/502, Aggregates, to Subcommittee B/502/6, Test methods, which has the responsibility to: aid enquirers to understand the text; present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep
7、the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European pub

17、d by Technical Committee CEN/TC 154, Aggregates, the Secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2001, and conflicting national standards shall be
18、 withdrawn at the latest by December 2003. This European Standard forms part of series of tests for bituminous bound filler aggregates. Test methods for other properties of aggregates will be covered by parts of the following European Standards: EN 932 Tests for general properties of aggregates; EN
19、933 Tests for geometrical properties of aggregates; EN 1097 Tests for mechanical and physical properties of aggregates; EN 1367 Tests for thermal and weathering properties of aggregates; EN 1744 Tests for chemical properties of aggregates. The other part of EN 13179 will be: Part 1: Delta ring and b
20、all test. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, N
21、orway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 4 EN 13179-2:2000 BSI 10-2000 1 Scope This European Standard specifies the procedure for determining the apparent viscosity of a water-filler aggregate mixture, expressed numerically. The test procedure is applicable to filler a
22、ggregate used in bituminous mixtures to regulate production control.2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed
23、 hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 932-

25、 purposes of this European Standard the following terms and definitions apply: 3.1 bitumen number amount of water, when mixed with 100 g of filler aggregate, to give a mixture with a defined apparent viscosity 3.2 laboratory sample reduced sample derived from a bulk sample for laboratory testing 3.3
26、 test portion sample used as a whole in a single test 4 Principle A filler aggregate mixture placed in a cylindrical cup is penetrated for 5 s with an aluminium stamp 8 mm in diameter with a mass of 15 g. The amount of water required to give a penetration of the stamp in the mixture between 5,0 mm a
27、nd 7,0 mm is determined.Page 5 EN 13179-2:2000 BSI 10-2000 5 Apparatus 5.1 All apparatus, unless otherwise stated, shall conform to the general requirements of EN 932-5. 5.2 Balance, accurate to 0,1 g. 5.3 Stainless steel dish, shaped like a truncated cone, height (65 5) mm, upper edge (95 5) mm in
28、diameter, with a flat bottom (65 5) mm in diameter. 5.4 50 ml burette. 5.5 Flexible spatula. 5.6 Cylindrical cup, inner diameter (30 1) mm, height (30 1) mm with a wall thickness of (2,0 0,2) mm. 5.7 Penetrometer, complying with EN 1426. 5.8 Round aluminium stamp, (8,0 0,1) mm in diameter, mass (15,
29、0 0,2) g, fitting into the penetrometer in place of the needle holder. 5.9 Timer, accurate to 0,1 s. 5.10 Demineralized water. 6 Preparation of test portions Reduce the undried laboratory sample to test portions in accordance with EN 932-2. At least three test portions with a mass of at least 50 g a
30、re required. NOTE A mechanical sampler can be used. 7 Procedure Weigh (50,0 0,1) g of undried filler in the stainless steel dish and add x 1 ml of demineralized water from the burette. Mix and stir for (300 10) s with the spatula. NOTE 1 x 1is the expected amount of water required to give a valid va
31、lue of penetration of the stamp into the mixture. NOTE 2 Care should be taken to spread the mixture as little as possible to prevent the water from evaporating. Fill the cylindrical cup with the mixture, ensuring that no air bubbles are entrapped and smooth the surface. Place the cup with the mixtur
32、e on the base of the penetrometer. Level the bottom of the stamp with the surface of the mixture, reset the dial to zero and allow the stamp to penetrate into the mixture for (5,0 0,1) s. Measure the penetration to the nearest 0,1 mm and the amount of water from the burette (x 1ml) to the nearest 0,
33、1 ml. If the penetration is smaller than 5,0 mm or greater than 7,0 mm, mix a further test portion with an adjusted volume of water (x 2ml) and repeat the procedure specified in this clause.Page 6 EN 13179-2:2000 BSI 10-2000 8 Calculation and expression of results Calculate the bitumen number BN in
34、accordance with the following equation: BN = 2x n where x n is the numerical value of the volume of water, in millilitres, used to give a test result with a penetration between 5, 0 mm and 7,0 mm. Express the calculated value to the nearest whole number. NOTE An indication of precision is given in a
35、nnex A. 9 Test report 9.1 Required data The test report shall include the following information: a) the apparent viscosity (bitumen number); b) reference to this European Standard; c) the name or the brand of the filler aggregate; d) the date of the test. 9.2 Optional data The test report can includ
