Road Markings

Thermoplastic Extrusion - Product Specification


A reflectorised thermoplastic road marking material available in various levels of Luminance, Skid Resistance & Reflectivity, and in various colours.

Extrusion materials are thermoplastics, which possess higher viscosities than spray plastic materials.

The application to the road surface is achieved by either an auger or a thermoplastic pump.

Extrusion thermoplastic product consists of a mixture of light coloured aggregates, pigment and extender bound together with a thermoplastic binder system.

The exact composition of an Extrusion thermoplastic grade will depend on the specification requirements, and is designed that when in a molten state, it can be extruded onto the road surface to give an even line of good definition.

In order to give good drainage characteristics, a drainage channel may be incorporated into the line at predetermined intervals.

Immediately following application of the line, a surface application of solid glass beads to
IS EN 1423 or equivalent shall be applied at a typical rate of 450 g/m2 by an applicator gun attached to the screed machine.

Lines are tack free within 2 minutes at an ambient air temperature of 15 C.


This process employs a mechanically propelled vehicle. Extrusion utilises an auger or pump from a thermostatically controlled tank to extrude the hot thermoplastic through a gate opening set to produce a line of pre-selected thickness of material onto the road surface. Glass beads are automatically applied to the molten line. For more details refer to our Thermoplastic Extrusion Method Statement.

Typical Uses

Generally used on new road construction projects, asphalt, tarmacadam and surface dressed roads.


Extrusion Thermoplastic is supplied in 25kg low melt polythene sacks. Each bag is 25kg of powder mixture and supplied in 1.5 tonne batches, covered and stretch wrapped for protection.


  • Enhanced wet night visibility
  • Immediate retroreflectivity
  • Low maintenance costs – single application of sprayed thermoplastic material immediately restores the Luminance & Retroreflective properties of the product.
