This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of hydraulic road binders, including certification of conformity of the factory production control. This document provides technical rules for factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing), assessment of the performance of the hydraulic road binder, initial inspection of the manufacturing plant and of factory production control and continuing surveillance, assessment and evaluation of factory production control. This document is intended to be linked with the Annexes ZA of the European Standards covering hydraulic road binders, i.e. EN 13282-1 and EN 13282-2. NOTE The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards.
