Asphalt Temperature Gauge
The temperature of the material in the
asphalt tank is shown on a dial
thermometer mounted on the rear or side
of the tank depending on configuration. The
thermometer must be monitored closely
whenever the burners are operating, as it is
essential that material never be heated to a
temperature higher than the supplier’s recommended maximum
temperature.
Preparation
Selection of Correct Spray Nozzles
When the desired rate of travel in feet per minute and the required
spread rate in gallons per square yard are known, the appropriate nozzle
size can be selected with the aid of the BearCat Road Oil Spreading
Calculator, which is furnished with the Model BC-502 /CRC distributor. If
the nozzles presently in the spray bar are not of a suitable size, change
them according to the instructions given below. Refer to the side of the
Calculator that represents your measurement system (English or metric).
On top, in the first window, align the required SPREADING RATE with
TRUCK SPEED. Then, in the 3rd window (Spray Bar Pressure), choose the
Nozzle that fits most closely in the range of 6 to 12 PSI. The acceptable
range is actually 5 to 25 PSI; however, since operation at the lower end is
preferable to minimize over-spray and contamination of the equipment,
the selected nozzle should be one that will yield the required coverage at
6 to 12 PSI. Additional information that should be derived with the
Calculator is the minimum spraying speed for the desired rate with this
nozzle. The minimum acceptable spray pressure for creating an
acceptable spray fan is 4 PSI.
If the spray bar is turned on at speeds lower
than the minimum acceptable travel speed, the spray pattern will be
unacceptable.
