645.03  Application.  Only apply on clean dry pavement surfaces.  If there is oil, salt or dust; power wash the pavement and allow the pavement to dry.

Furnish the Engineer with the manufacturer’s application instructions.  Record the surface temperature and date of application.  Furnish documentation to the Engineer.  Apply preformed markings to the pavement by means of a precoated adhesive on the back, or by an adhesive or activator furnished with the markings and used according to the manufacturer’s 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 not use preformed markings that are subject to premature adhesion or 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.

B.      Type B and Type C Marking Application.  Apply the preformed markings according to the manufacturer’s recommendations.
