Inspection and testing of incoming constituent materials

4 INSPECTION AND TESTING OF INCOMING CONSTITUENT MATERIALS AND DELIVERED PRODUCT 

Part of the FPC system requirements specified by CEN EN 13108-21 (2008) is inspection and testing on incoming constituent materials and on finished bituminous mixture (delivered product). As constituent materials, the following are distinguished aggregates, filler, binders, additives and reclaimed asphalt. 

The aim of the inspection and testing of the above is to ensure product quality and compatibility with the predetermined requirements. 

The constituent materials, such as aggregates, filler, binders, additives and reclaimed asphalt, should be inspected and tested on a regular basis. 

The inspection/test frequency and the types of tests per incoming constituent material are all covered in CEN EN 13108-21 (2008). Table 9.2 gives an example of minimum inspection/test and the frequency recommended for aggregate and binder.
