Spray paving steps
There are six basic sequential steps to spray paving (details of each step
are described below):
1.
Load emulsion in the tank(s): Fills the tanks with emulsion (page
74)
2.
Circulate the tank(s): Heats up the pumps and valves before
spraying (page 80)
3.
Circulate the spray bar: Heats and charges the spray bars before
spraying and prevents emulsion cooling and clogging when
spraying is paused (page 81)
4.
Spray emulsion: Applies emulsion to the paving surface (page 82)
5.
Vacuum the spray bars: Pulls emulsion back in the tank when
spraying is complete (page 84)
6.
Clean out and rinse the spray bars: Cleans the system after use to
prevent clogging (page 85)
Loading emulsion in the tank(s)
Warning:
Wear protective gear for face, hands, feet and
body when working with hot material.
Warning:
Take extra care when cutback emulsions are
used. They have a much lower flash point thereby posing a
greater risk of explosion. Verify maximum temperature allowed of
product and spray paver before heating.
Warning:
Do not mix different asphalt emulsion materials
in the tank. Clean tank and the circulating system before adding a
different substance.
