PREFORMED THERMOPLASTIC ROAD MARKINGS
It is possible to purchase reformed thermoplastic road markings in one metre strips as shown here, it is also possible to buy it in "rolls" of longer length, but the principle is the same as shown here.
The principle being is that they are thermoplastic, so carefully applied heat to the road surface and the preformed road marking will bond it to the road surface without damaging the thermoplastic.
The process is fairly self explanatory if you follow the photographs. I must add that there is only so many people about is because this was a demonstration of the product.
The procedure could quite easily be carried out by a small patching gang after laying the patch or by an "emergency gang" / "highway patrol gang" that most local highway authorities possess. You can see that you do not need a lot of equipment, and it is likely that the gang will already be carrying it for other uses.
Just use the correct amount of heat, i.e. just enough to make the thermoplastic molten, so that it will bond with the road surface, and that is all.
Preheating the road surface to which the preformed thermoplastic road marking is to be applied.
|Removing the preformed line from the backing paper and applying it to the preheated road surface.
Carefully heating the applied preformed thermoplastic road marking until it is molten thus ensuring a complete bond with the road surface.

The process being repeated to achieve an unbroken continuation of the double yellow line system.
