Current development of road markings given the ever-increasing volume of road traffic and the need to improve safety, road marking is likely to have the greatest impact on road users in all forms of traffic guidance and information, especially at night. Less than a hundred years ago, the first road markings were officially recognized as an aid to road traffic.

The original white line was hand-painted, and it wasn't until the early 1940s that thermoplastic screeds were used because of the lack of solvent in fuel paints.
Thermoplastics have been the solution to the UK road marking market for years as they are relatively easy to use in most conditions, 12 months a year.
In the late 1990s, the thermoplastic road marking material was refined to match the material recipe and application thickness in tender documents.
In the case of retro-reflectivity, this is achieved by the percentage and type of glass bead in the mixture and first applied to a new marker surface.
The inability to hold the glass beads applied to the surface and the reliance on the wheels of the vehicle to expose the glass beads present in the material in some cases result in the product being unable to provide adequate retro-reflective capability at night.
Despite the exclusive use of thermoplastics in the US for road marking, paint remains the first choice for approximately 70% of the global road marking market due to its high lighting efficiency and retro-reflective capabilities.
