Paint Application Equipment
1.5.1.1
Self-Propelled or Mobile-Drawn Pneumatic Spraying Machines
The equipment to apply paint to pavements shall be a self-propelled or
mobile-drawn pneumatic spraying machine with suitable arrangements of
atomizing nozzles and controls to obtain the specified results. The
machine shall have a speed during application not less than 8 km/hour 5 mph,
and shall be capable of applying the stripe widths indicated, at the paint
coverage rate specified in paragraph APPLICATION, and of even uniform
thickness with clear-cut edges. [Equipment used for marking streets and
highways shall be capable of placing the prescribed number of lines at a
single pass as solid lines, intermittent lines or a combination of solid
and intermittent lines using a maximum of two different colors of paint as
specified.] [The equipment used to apply the paint binder to airfield
pavements shall be a self-propelled or mobile-drawn pneumatic spraying
machine with an arrangement of atomizing nozzles capable of applying a line
width at any one time in multiples of 150 mm 6 inches, from 150 mm 6 inches
to 900 mm 36 inches]. The paint applicator shall have paint reservoirs or
tanks of sufficient capacity and suitable gauges to apply paint in
accordance with requirements specified. Tanks shall be equipped with
suitable air-driven mechanical agitators. The spray mechanism shall be
equipped with quick-action valves conveniently located, and shall include
necessary pressure regulators and gauges in full view and reach of the
operator. Paint strainers shall be installed in paint supply lines to
ensure freedom from residue and foreign matter that may cause malfunction
of the spray guns. The paint applicator shall be readily adaptable for
attachment of an air-actuated dispenser for the reflective media approved
for use. Pneumatic spray guns shall be provided for hand application of
paint in areas where the mobile paint applicator cannot be used.
