43、d to form an asphalt mixture 3.3 maximum mixing temperature value that an asphalt mixture shall not exceed during the mixing process 4 Principle The bituminous mixture is prepared at a target temperature within a time that is limited in order to reduce mechanical degradation of the aggregates. The t
44、arget temperature depends on the grade of bitumen. NOTE The target temperature for mixing is related to the reference temperatures used for its subsequent compaction. 5 Apparatus 5.1 Laboratory mixer, capable of entirely coating all mineral substances in not more than 5 min and, preferably equipped
45、with thermostatically controlled heating and mechanical speed control. The mixer shall be of the whisk or other type that is not so rigid that it can damage either the aggregate particles or the bowl. 5.2 Ventilated oven, for heating aggregates and bitumen up to the relevant target temperature from
46、Table 1 to the accuracy given in EN 12697-38. 5.3 Balance, capable of measuring the mass of the intended mixture to the accuracy given in EN 12697-38. 5.4 Thermometer, capable of measuring the relevant target temperature from Table 1 to the accuracy given in EN 12697-38. 5.5 Hot plate. Adjustable ho
47、t plate, capable of maintaining the required target temperature during the manual mixing to the accuracy given in EN 12697-38. 6 Procedure 6.1 Mixing temperature 6.1.1 Unless given in the European Standard for the compaction device to be used (!EN 12697-30:2004+A1“, EN 12697-31, !EN 12697-32:2003+A1
48、“ or !EN 12697-33:2003+A1“), the reference temperature for mixtures with paving grade bitumen to EN 12591 shall be taken from Table 1. For mixtures with modified binders or other additives, the reference temperature shall be selected so that the binder has a viscosity to EN 12595 that is similar to
49、those provided in Table 1. For mixtures with reclaimed asphalt, the reference temperature shall be calculated using the overall penetration calculated from the penetrations and proportions of both the added binder and the binder recovered from the reclaimed asphalt !in accordance with Annex A of EN 13108-1:2006, EN 13108-2:2006, EN 13108-3:2006
