Coloured Thermoplastic

Description

Coloured thermoplastic is an excellent durable anti-skid treatment for all road surfaces

Application
  • It is laid in a single layer and contains calcined bauxite aggregate throughout its depth, (usually 3/5mm, ensuring that new calcined bauxite is exposed as the surface wears.).This product can be applied all year round onto new and old surfaces. Our design and technical personnel are available for site visits and discussion to ensure a cost-effective solution.

    Coloured thermoplastic is laid at a temperature of 160/170°C and has instant bond to the surface through heat transfer to underlying surface.

  • Spread rate 90/100 square metres per tonne
  • Initial texture depths 1.1+-0.3m
  • Colours: red, green, grey, buff
  • Application temperature 160/170°C
Features
  • Coloured thermoplastic is ideal for use on sharp bends, bridges, approaches to roundabouts, pedestrian crossings, junctions, ghost islands, railway platforms, ramps, cycle lanes, traffic islands, wheel chair, road sign works.

    COLAS Contracting also have a dedicated Road Signs division devoted to the recording, maintenance and erection of fixed assets throughout the national road network across Ireland. By using the very latest in asset recording technology it enables COLAS Contracting to accurately and efficiently record all fixed signs on the roadside using Trimble handheld recording Juno's.

Resin Based Surface Treatment

Description

The spray grip system combines a tough flexible cured Bitumen Extended Epoxy Resin with Calcined Bauxite aggregate; an outstanding aggregate which demonstrates an extraordinary resistance to polishing and abrasion. This aggregate combined with Bitumen Extended Epoxy Resin has proven over the past 30 years to be the best for performance and cost.

Application

The bitumen extended epoxy resin is sprayed directly onto the road surface by specially designed equipment at a predetermined rate, followed by an even distribution of specially graded Calcined Bauxite chipping.

Where to use
On the approaches to:

  • Pedestrian crossings
  • Traffic signals
  • Roundabouts
  • Junctions
  • Motorway junctions
  • Fast bends
Features
Calcined Bauxite has the following values; psv of 75 / 83, A.A.V. of 4, hardness of 9.
Benefits
  • Wet weather braking distance down by 33%
  • Wet weather accidents cut by up to 57%
  • Total accidents reduced by up to 15%
  • Minimum surface preparation and maintenance
  • No need to replace existing road markings
  • Long effective life
  • Resistance to oil and solvent spillage

MMA Based Treatment

Description

Semi liquid 2K -metacrylic based coating intended to achieve adhesion and embedment of antiskid aggregates (calcinated bauxite) to provide efficient and durable high friction road surface.

Application

The metacrylic based costing is sprayed directly onto the road surface by specially designed equipment at a predetermined rate, followed by an even distribution of specially graded Calcined Bauxite chipping.

Features
Calcined Bauxite has the following values; psv of 75 / 83, A.A.V. of 4, hardness of 9.
Benefits
  • Durable high friction road surface
  • Minimum surface preparation and maintenance
  • No need to replace existing road markings
  • Long effective life
  • Resistance to oil and solvent spillage
  • Curing Time - 30 to 40 mins at 20°C
