37、.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

38、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 in

39、dicated 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 t

40、he oven 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

41、 that binder.
