Determination of mixture properties for optimum performance

The stage for determining the properties of the cold asphalt consists of determining the target mix in order to satisfy the requirements stated in Table 6.2. 

The specimens, 100 mm in diameter by approximately 62.5 mm in height, are compacted by a Marshall compactor (50 blows) and tested at 21°C 1°C after curing for 48 h. A 

Retained stability (%) (48 h in water bath, room temperature) 50 50 

Behaviour in permanent deformation (when ESAL 3000 per day) The target binder content should be less than the maximum permissible determined (see Section 6.3.3.3)
