Binder Content - Bitumen Extraction

The determination of binder content of bituminous mixtures is one of the major properties that affect pavement performance. The binder content affects the pavement’s tendency to permanent deformation, fatigue cracking and moisture damage.

The binder content can be determined by ignition method and hot/cold extraction. However due to environmental, economical, health and safety concerns, Matest investigated alternative methods to determine binder content developing innovative devices that combine all the processes associated with bitumen extraction and recovery.
