Thermoplastic coloured surfacing

  • • Highlights areas to the road
  • • Quick and easy to apply
  • • Hot thermoplastic binder
  • • Hand screed applied to the surface
  • • Easily delineates traffic

Thermoplastic coloured surfacing plays an important part in achieving a duty of care to the road user.

Used to highlight areas to the road user such as red surfacing “don’t drive here”, coloured surfacing is a quick and efficient method of passing this message on. Recognised across the UK, coloured surfacing has become a common sight on the highway and as such can be relied upon to impart the message clearly and succinctly.

What makes the colour?

There are two elements to creating a coloured surface and ensuring long term colour retention.
Aggregates: Aggregates used are chosen to be as close to the required colour as possible, such as naturally occurring red aggregates for red surfacing. Additionally dyed aggregates are available when particularly strong colouring is required.
Binder: The binder is thermoplastic rather than the traditional bitumen base commonly used in roads. This thermoplastic does not start with a ‘black’ base like oil based products, but a neutral base. This makes it very easy to colour with dyes. The dyes chosen for our coloured surfacing have been tested to ensure they have a long life colour retention and resistance to ultra violet light degradation.

Material thickness

Coloured surfacing is a veneer treatment applied on top of the existing surface. The finished product is typically 3mm to 5mm in thickness.

Installation

Heated on site in a specialist boiler, the material is transferred to a screed box in a molten state. The material is then screeded onto the road surface and allowed to cool (approximately 20 to 30 minutes).

Colour choice

  • • Red
  • • Green
  • • Buff
  • • Grey
  • • Yellow

Cycleways & footways

Coloured surfacing is available in a cycleway / footway grade for the expected lighter traffic volumes. The aggregate sizing is smaller than used on roads, making the surface less rough textured, thereby giving a smoother ride to the cyclist and reduced trip hazard to pedestrians.
