After specified pre-conditioning procedures depending on the viscosity of the binder, the mixture is immersed in water in a glass container. After a given time under specified conditio
27、ns, the percentage of the aggregate surface covered with binder is assessed visually. 5 Reagents and materials 5.1 Reference aggregate, as light in colour as possible, or aggregate from a specific job site, which either passes through a sieve having a mesh size of 10 mm and is retained on a sieve ha

34、5.1) with 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
35、 be tested, 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 i
36、ndicated in Table 1. The efflux time shall be determined in accordance with EN 13357 and dynamic viscosity at 60 C in accordance with EN 14896 or EN 13702-1. Closed containers shall be used and care shall be taken to avoid local overheating and any loss of volatile constituents. Leave the binder in
37、the oven for the minimum time to ensure that it reaches the temperature given in Table 1. NOTE 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 temperatu
38、re for that binder.

42、ied for cut-back and fluxed bituminous binders with an efflux time 10 mm 40 C (EN 13357) higher than 500 s or with a dynamic viscosity at 60C (EN 14896 or EN 13702-1) 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 th
43、e heating plate maintained at the temperature specified in 8.1.3. Pour (200 2) 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 must remain on the heating plate during mixing. Remove the dish from the heating pl
44、ate and ensure by periodic stirring that aggregates remain properly coated until binder 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. 8.2.3 Pour approximately 300 ml of water (5.2) that has been pre-heat
45、ed 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). 8.2.4 Assess the surface coated with the film of binder according to the grading scheme given in Clause 9. 8.3 Procedure for “low viscosity” cut-back and fluxed
46、 bituminous binders 8.3.1 This procedure is to be applied for cut-back and fluxed bituminous binders with an efflux time 10 mm 40 C (EN 13357) lower or equal to 500 s or with a dynamic viscosity at 60C (EN 14896 or EN 13702-1) lower or equal to 10 Pa s. 8.3.2 Pour (20 2) g of binder prepared as indi
47、cated in 8.1.3 into the pre-heated dish and place the dish onto the heating plate 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 must remain on the
48、 heating plate (6.11) during mixing. Remove the dish from the heating plate (6.11) 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 (30 + 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.
