required, follow the requirements of Air Force
Engineering Technical Letter (ETL) 97-16 "Pavement
Marking System for Low Temperature Applications."
**************************************************************************
Apply paint to clean, dry surfaces, and unless otherwise approved, only
when air and pavement temperatures are above 5 degrees C 40 degrees F and
less than 35 degrees C 95 degrees F for oil-based materials; above 10
degrees C 50 degrees F and less than 43 degrees C 110 degrees F for
water-based materials. Maintain paint temperature within these same limits.

EQUIPMENT
**************************************************************************
NOTE: Where pavement marking is limited to small
street and parking areas, use first paragraph
entitled "Paint Applicator."
**************************************************************************
Machines, tools, and equipment used in the performance of the work shall be
approved by the Contracting Officer and maintained in satisfactory
operating condition. Submit construction equipment list approval by the
Contracting Officer.

Paint Applicator
**************************************************************************
NOTE: Select the applicable paragraph(s) from the
following:
**************************************************************************
[Provide hand-operated push-type applicator machine of a type commonly used
for application of paint to pavement surfaces. Paint applicator machine
shall be acceptable for marking small street and parking areas. Applicator
machine shall be equipped with the necessary paint tanks and spraying
nozzles, and shall be capable of applying paint uniformly at coverage
specified.] Applicator for water-based markings shall be equipped with
non-stick coated hoses; metal parts in contact with the paint material
shall be constructed of grade 302, 304, 316, or equal stainless steel.
[Provide self-propelled or mobile-drawn pneumatic spraying machine with
suitable arrangements of atomizing nozzles and controls to obtain the
specified results. Provide machine having a speed during application
capable of applying the stripe widths indicated at the paint coverage rate
specified herein and of even uniform thickness with clear-cut edges.
[Provide equipment used for marking streets and highways 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 three different colors of paint as specified.] [The equipment
for applying the paint for airfield pavements will be a self-propelled or
mobile-drawn pneumatic spraying machine with an arrangement of atomizing
nozzles capable of applying a width of line at any one time in multiples of
150 mm 6 inches, from 150 to 900 mm 6 to 36 inches.] Provide paint
applicator with paint reservoirs or tanks of sufficient capacity and
suitable gages to apply paint in accordance with requirements specified.
Equip tanks with suitable air-driven mechanical agitators.
Equip spray
mechanism with quick-action valves conveniently located, and include
necessary pressure regulators and gages in full view and reach of the
operator. Install paint strainers in paint supply lines to ensure freedom
