34、 water (5.2) and dry it in the ventilated oven (6.2) for a minimum of 12 h at (110 5) C. 8.1.2 The quantities of aggregates needed for the tests to be carried out under 8.2 and 8.3 shall be weighed into adequate containers by batches of (200 2) g and/or (400 4) g. Depending on the binder to be teste
35、d, bring the aggregates and the dish(es) to be used for the mixing procedure to the temperature indicated in Table 1 and maintain this temperature for about 2 h. 8.1.3 A binder sample of a minimum amount of 200 g shall be prepared in accordance with EN 12594 and brought to the temperature indicated
36、in Table 1. The efflux time shall be determined in accordance with EN 12846-2 and dynamic viscosity at 60 C in accordance with EN 13302 or EN 13702. Closed containers shall be used and care shall be taken to avoid local overheating and any loss of volatile constituents. Leave the binder in the oven
37、for the minimum time to ensure that it reaches the temperature given in Table 1. Binder formulated with an adhesion improver should be tested under the representative conditions of its use, i.e. after one or several days of storage in a closed container at the typical storage temperature for that bi

41、gher than 500 s or with a dynamic viscosity at 60 C (EN 13302 or EN 13702) higher than 10 Pa s. 8.2.2 Pour (10 1) g of binder prepared as indicated in 8.1.3 into the pre-heated dish and place the dish onto the heating plate (6.11) maintained at the temperature specified in 8.1.3. Pour (200 2) g of a
42、ggregates prepared as indicated in 8.1.2 onto the binder and mix with a spatula until coating is completed, but no longer. The dish shall remain on the heating plate during mixing. Remove the dish from the heating plate and ensure by periodic stirring that aggregates remain properly coated until bin
43、der drainage stops. Once at ambient temperature put the mix in a beaker (6.6) and cover it with a watch-glass (6.7); let it rest for (30 5) min. BS EN 15626:2016EN 15626:2016 (E) 8 8.2.3 Pour approximately 300 ml of water (5.2) that has been pre-heated to (60 3) C into the beaker; cover the beaker w

45、ied for cut-back and fluxed bituminous binders with an efflux time 10 mm 40 C (EN 12846-2) lower or equal to 500 s or with a dynamic viscosity at 60 C (EN 13302 or EN 13702) lower or equal to 10 Pa s. 8.3.2 Pour (20 2) g of binder prepared as indicated in 8.1.3 into the pre-heated dish and place the
46、 dish onto the heating plate (6.11) maintained at the temperature specified in 8.1.3. Pour (400 4) g of aggregates prepared as indicated in 8.1.2 onto the binder and mix with a spatula until coating is completed but no longer. The dish shall remain on the heating plate during mixing. Remove the dish
47、 from the heating plate and ensure by periodic stirring that aggregates remain properly coated until binder drainage stops. Once at ambient temperature, separate the mix into approximately two equal parts: 8.3.3 Put the first part in a beaker (6.6) and cover it with a watch-glass; let it rest for (3
48、0 5) min. Then pour approximately 300 ml of water (5.2) at ambient temperature into the beaker; cover the beaker with a watch-glass and let it rest for (20 4) h at ambient temperature. 8.3.4 Spread the second part on a watch-glass (6.7) and place it in the ventilated oven (6.1) for (24 1) h at (60 3
49、) C. Care shall be taken to properly spread out the coated aggregates on the watch-glass to ensure a single layer. Then transfer the mixture in a beaker (6.6), pour roughly 300 ml of water (5.2) that has been pre-heated to (60 3)C into the beaker; cover the beaker with a watch-glass and place it in the ventilated oven at (60 3) C for (20 4) h (6.1). With low viscosity binders, in particular those incorporating non- or low-volatile flux oils, binder drainage can occur d
