Abstract:
Disclosed is an alkyd or hydrocarbon resin-based pre-manufactured thermoplastic airport runway signage that is applied in relatively large sections onto an airport runway where the alkyd or hydrocarbon resin-based composite includes a functionalized wax incorporated in the resin-based composite within the range of 0.2 to 3 percent by weight, thereby allowing the resin-based composite to exist in a molten state within a viscosity range of between 35,000 and 85,000 centipoise and wherein the top surface provides an area for surface indicia materials existing on the top surface together with retroreflective glass beads with an index of refraction of 1.9 such that when the beads are suspended in and applied on the surface of the resin-based composite in a molten state the beads do not sink into the resin-based composite provide for allowing and maintaining an overall retroreflectivity of about 1000 millicandellas/m2/lux (mcd).
