EN 12697-18:2004 (E) 6 1 Scope This document describes two test methods: basket method (see clause 4), Schellenberg method (see clause 5). The basket method (see clause 4) describes a method
34、 for determining binder drainage of bituminous mixtures. This method directly measures binder drainage, but when carried out on bituminous mixtures with fibres or mixtures whose mortar content is higher than in porous asphalt some clogging of the holes in the drainage baskets can occur, limiting the
35、 drainage of the binder. Basket method can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to
36、be quantified. The Schellenberg method (see clause 5) describes a method for determining binder drainage of bituminous mixtures. It is applicable to asphalt materials that are not porous asphalt or for those porous asphalt incorporating fibres. It can be used either for determining the binder draina
37、ge for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified. 2 Normative references The following referenced documents are indispensable

41、iple The quantity of material lost by drainage, after 3 h at the test temperature (see 4.4.1) is measured in mixtures placed on baskets made out of perforated metal plates. 4.2 Materials Sufficient aggregates and binder to manufacture at least 4 kg of asphalt material. If more than one binder conten
42、t is going to be tested, aggregates and binder to manufacture 2,5 kg of asphalt material per each additional binder content shall be provided. The aggregates shall be dried to constant mass and graded in the fractions appropriate to the specified grading. The test can be carried out with samples tak
43、en during the factory production control. In that case, sampling shall be in accordance with EN 12697-27. 4.3 Apparatus 4.3.1 Oven with closed ventilation system, vibration free, fitted with thermostatic control to maintain the temperature in the vicinity of the samples to 2 C in the range of 80 C t
