Thick-layer horizontal marking

The thick-layer horizontal road marking is characterised by high durability, resistance to abrasion and excellent day and night visibility. It may be applied on heavy traffic roads, areas of large vehicle traffic as well as in the places with the longest expected duration period (pedestrian crossings, road stop lines and direction arrows).

For thick-layer marking we use materials, the applied layer of which measures 0.9-11mm. The materials are divided into:

  • hot-applied thermoplastic signs
  • cold-applied two-component signs, chemically hardened
  • glued or in-melted prefabricated materials

We cooperate with such manufacturers as 3M, Grawil, Triflex or Rembrantin.

Thermoplastic signs
This type of marking is made by heating of powdered thermoplastic mass up to 190-210oC and applying it on the surface with extruder, drag shoe or manually with plastomarker. Then it is cooled to obtain cohesive surface. This type of marking is the best value for money. Depending on marking type, the material consists of up to 40% of glass balls which retain required parameters through the entire service life of signs. The balls have excellent resistance to abrasion, sunlight and brine. Due to their very good properties, they may be used on town and transit roads. It is made with the technique called structural line method (Drop On Line, Multi Dot), smooth lines, acoustic lines (Crosswise Hump, Barrettes) extruded lines or sprayed lines (Sprayplast). Thermoplastic structural lines ensure perfect day and night visibility, even in very humid conditions or during rainfall, allowing for proper rainwater drainage.
The lines have acoustic property to create a knocking warning noise when a tyre crosses the line.

Chemically hardened marking
This type of marking is obtained by mixing adequate amounts of one or two components with the hardening agent, which react and produce adhesive surface after applying. The mass consists of pigments, filling materials, synthetic resins and glass microballs. This type of marking is ready for traffic within 10 minutes after being applied. It is coarse and resistant to adverse weather conditions and brine. The required irradiation is obtained by pressure floating of glass microballs of adequate granulation and proper light refraction coefficient. This latter process is performed after application of the mass. Chemically hardened marking is made by means of the smooth lines, structural and acoustic lines and spraying, with the line thickness of 0.9 - 6mm. The most frequently utilised are structural and acoustic signs due to their numerous advantages as well as lower material use.

They are characterised by smaller adhesiveness and density. This allows for the use of spray application and obtaining of thinner layer, which, however, is much more durable than that made with solvent-based paints. This technique is widely used for making new marking as well as for economic repairs of old and worn thick-layer signs.

Prefabricated materials
These are glued, melted or in-built materials, which include:

  • thermoplastic mass (premarks), prepared in sheets for hot in-melting as separation lines, crossroad stop lines, pedestrian crossings and sings glued directly to the road surface.
  • adhesive films for applying on new surfaces as separation and road edge lines.
  • spot reflective elements, glued onto separation of road edge lines and traffic excluded areas.

The application films are multi-layer tapes (marking line width), consisting of polymer layer, filling material as well as coursing and reinforcing materials. The surface layer includes abrasion resistant polymer and glass balls which ensure proper night visibility. The shape of the layer ensures adequate water drainage and skid protection.
