Preformed Tapes — Performance
Preformed plastic tapes generally have good durability and
abrasion resistance. Preformed tape typically exhibits better performance
on bituminous asphalt pavement than on hydraulic cement concrete
because of the adhesive characteristics. Inlaid tapes almost always
outperform overlaid tapes. Tapes are known to distort in areas
that have a high amount of turning movements or weaving over the
markings.
A clean surface is more important for tapes
than for any other material. Therefore, tapes must be applied in
areas where good bonding can be ensured.
If applied
properly, tapes can provide durability and visibility for many years.
In most cases these materials are so durable that the tape material
will typically outlast its retroreflective properties.Preformed plastic tapes are most commonly used for shortline
markings, including: crosswalks, stop bars, and words and symbols.
However, their use as a longline application is increasing nationwide.
Permanent tapes are well suited for severe conditions where frequent
replacement is required due to their ease of application. Temporary
preformed tapes can be used in construction or maintenance jobs
requiring temporary delineation or altered travel lanes. Preformed
tapes require little or no equipment to apply and the roadway is
open almost immediately after installation.
