recommendations. Form lines 12 inches (300 mm) wide or less by one
piece; form lines wider than 12 inches (300 mm) by no more than two
pieces. Do not overlap individual pieces. Do not allow a gap
greater than 1/4 inch (6 mm) between pieces.
Do

contamination before placement.
Apply
preformed markings according to the appropriate type of application as follows:
A. Type A Marking Application. Apply the preformed markings while the pavement
surface temperature is at the manufacturer’s application recommendations.
Before any application, test and record the pavement surface temperature, air
temperature and dew point. Retest and record every 4
hours of operation. Demonstrate to the Engineer the testing
devices are accurate and operational. Initially position the marking
under light pressure, or use a hand operated light roller or mechanical
applicator. Once correctly located, hold the marking in position without
delay by rolling.
If Type A preformed markings are specified to be inlaid on newly
placed asphalt concrete, press the markings into the warm surface using a
mechanical roller. Proper application of inlaid markings requires that
the asphalt concrete pavement surface have a temperature below the maximum
temperature recommended for the preformed material or its adhesive backing.

manufacturer’s recommendations.
