controls the blending of virgin and recycle materials to obtain
exact job specifications of the produced asphalt
mix. The system controls start/stop and rate for both liquid

full automatic or true manual (backup) operation which is totally
independent of the electronics. DIGI-BLEND™ is
compatible with plants having liquid asphalt meters that provide
1000 PPG (pulse per gallon) output and belt scales that have
industry standard milli-amp outputs (4-20 or 0-20 ma).
DIGI-BLEND™ has single control
board design which provides control functions usually handled
by multiple circuit boards
in other systems. The single control board’s visual display
features help a qualified plant electrician determine if the
system is operating satisfactorily and provides clues as to
what other equipment may have caused plant malfunction. DIGI-BLEND™ design
concept also eliminates the requirement of a factory trained
technician to recalibrate the control board when a plant
is moved to a new location or if replacement is ever required.
DIGI-BLEND™ includes pre-wired operator panel, control
electronics and complete true manual backup.
