HMA:
Hot Mix Asphalt.
Idle Mode:
This mode is entered on startup
after initialization. Revision “I”
software automatically transfers
from the program mode to the
idle mode upon completion of the
test. The furnace will idle at set
point temperature in preparation
for the next test. The blower is
“OFF” in the idle mode.
Initialization:
This procedure sets up and con-
figures the furnace for operator
use when the Power Switch is
depressed to “ON”. Initialization
time is approximately 5-15 sec-
onds.
Lift Test:
This test measures the blower
efficiency when the furnace is in
an unloaded condition and is at
room temperature. The operator
is required to tare the balance,
depress the start-stop key, and
observe the balance display.
Normal lift measurements are
minus 3.5-10 grams.
NCAT:
National Center for Asphalt
Technology.
Offset Value:
This value is the temperature dif-
ference between the stabilized
chamber displayed temperature
value and the chamber tempera-
ture verification value determined
by the External Digital
Thermometer.
Program Mode:
This mode is entered by depress-
ing the start-stop key. The pro-
gram mode is used to determine
asphalt content of a HMA sample,
calibration of the HMA sample, or
raw aggregate.
