The manufacturer’s application procedures for preformed tape must be strictly followed.

A clean pavement surface is very important for tapes to achieve a good bond. Preformed tapes may be inlaid or overlaid. Inlaid markings will outperform overlaid markings if a good bond is achieved. Tire traffic over the tape installation will help achieve a good bond. Tapes should not be installed on tine-textured concrete pavement, as the materials will be easily removed by tire wear. Installation of the tape on a deteriorated asphalt pavement surface will accelerate abrasion and adhesion failures.

Inlay Method.

The inlay method is preferred on newly constructed or resurfaced asphalt pavement. The asphalt should still be warm, approximately 130°F. Application usually follows the pavement breakdown roller. The tape is then rolled into the pavement surface with a steel drum roller during the final rolling of the pavement. The roller fuses the plastic into the hot asphalt surface creating an excellent bond and sealing out moisture.

Overlay Method.

On existing pavement and concrete pavement, the overlay method is used. The overlay method is also often used on new pavement surfaces, although the inlay method is preferred due to superior performance. The tape is applied directly on and bonded to the surface with an adhesive. Pressure-sensitive adhesives work best when overlaying permanent tapes on new asphalt pavement surfaces. The use of contact cement is recommended when installing the tape on concrete or over older markings. Manufacturers suggest 2 coats on the pavement surface and 1 coat on the tape. This is also true for all surfaces with heavy turning or weaving movements over the markings. Markings are initially bonded with a light hand roller or vehicle tire and permanently bonded by traffic wear.
