ABSTRACT:
Disclosed is an alkyd resin-based pre-manufactured thermoplastic airport runway signage that is applied in relatively large sections onto an airport runway. The pre-manufactured preformed thermoplastic formed as a continuous sheet and wound onto a take-up spool. The runway surface is prepared with a CCS epoxy primer and the preformed thermoplastic is unwound from the take-up spool and positioned onto the runway surface. When the pre-manufactured thermoplastic signage is in a desired location it is initially rolled conforming to the runway surface. Heat is applied to the rolled surface to a preferred temperature with an infra-red (IR) heater to melt and adhere the pre-manufactured thermoplastic signage into the runway surface.
