Asphalt Spraybar
This component of the Distributor is considered the
most important component It is through the spraybar
that the asphalt will be applied to the road surface
For best results, use the right size nozzle and proper
spraybar height for your type and grade of asphalt and
specific application rate. Before starting a job, check
the nozzles for damage and proper settings
Spray Pattern
1 Set the long axis of the nozzle openings to 20
degrees ( Figure 6-4) so that the spray fans do not
interfere with each other This setting will give the
best coverage without interference with the spray
pattern
2 Check the angle using the Nozzle Alignment
Wrench provided with your unit (see Valves And
Nozzles in Section 6)
Spraybar Height
NOTE: Although there is rarely a difference in fan
patterns as the truck load lightens, if you notice a
change in the pattern, you may need to readjust
the height of the bar
1 Set the spraybar height to provide exact triple
coverage of the spray fans ( Figure 6-5) Usually
this coverage is found when the bar is set 9 to 11
inches (23 to 28 cm) above the ground
NOTE: Different weights of material require slightly
different heights Generally, lighter weight
materials should be sprayed at closer to the 9
inch height, while heavier weight material will
need to be sprayed at a height closer to the 11
inch height
2 To set the height, measure from the bottom of the
nozzle to the ground, since the nozzle extends
below the bar The operator will have to try spraying
to see which height gives the best coverage
NOTE: Be sure the spraybar height is set properly
to obtain a uniform asphalt spread It is also
important to maintain the correct height during
the spraying procedure
3 Once the best spraybar height has been
determined, set the support chains by locking into
the slot so there is no more than 13 mm (1/2 inch)
variance during the spraying operation
