Surface Dressing

Surface Dressing

We offer all types of specialist surface dressing to provide carriageway, footway, driveway, canal towpath or car park operators with a cost-effective solution to seal and protect the highway surface, increase skid resistance and/or provide enhanced aesthetic value through the use of decorative aggregates. 

We use polymer modified binders (PMBs) on all our surface dressing operations to ensure maximum shear strength, maximum chipping bond, and to reduce sensitivity to higher road temperatures. 

We offer aggregate sizes ranging from 6mm and 10mm, to 14mm available in a variety of colours and can be combined through double dressings, racked in dressings and alternative scheme layouts. 

Our specialist, bespoke plant for footway surface dressing is designed and constructed at our in-house, specialist workshop, using our expert knowledge and experience in this area. 

All plant is fully calibrated to ensure an accurate rate of spread (ROS) of the bitumen emulsion binder and chippings and an onboard heating system ensures that the polymer modified bitumen is applied at an optimum temperature.

Targeted Surface Dressing

We are pleased to bring the Targeted Surface Dressing technique to the UK market from mainland Europe, where it has been used extensively in France and Germany. Target dressing is the ability to apply surface dressings to selected areas of the carriageway surface. An in-cab video/computer allows the operator to select the defective sections of carriageway in advance of the combination sprayer. The surface dressing is then applied to those selected areas as the vehicle passes over them. This fast and targeted approach to surface dressing provides large savings in resources, carbon, cost, time, and inconvenience to road users.

By using target dressing as a means to seal all existing NRSWA reinstatements, patches, cracks and fretting, the highway authority and asset owner is eradicating the formation of potholes in the future (at 10% of the cost of treating potholes).

Benefits include:

  • Works completed quickly (application is up to 3,000 sq.m./day) with only 2 vehicles and 4 operatives required, creating much less disruption.
  • Will move amber roads to green or at least maintain a light amber condition and enables a reduction in the long-term, whole-life cost of repairs.
  • Seals and protects existing patches, reinstatements, and joints in the carriageway surface.
  • Avoids costly third-party insurance claims for pothole damage.
  • Improves public perception by minimising the need for disruptive road closures and traffic congestion.
  • More environmentally friendly when compared to traditional options used.
  • Provides an excellent system for the reinstatement of surface dressings to NRSWA trench reinstatements.
Surface Dressing SAMI’s (Stress Absorbing Membrane Interlayer)

This technique offers a robust alternative to a carriageway ‘plane and patch’ solution. A 200 pen straight-cut bitumen binder is applied directly onto the pre-swept carriageway surface. The SAMI forms a protective barrier between the new surface dressing and the defective carriageway.

By combining the SAMI application with the surface dressing operation, highway engineers can eliminate pre-patching costs and the associated traffic management and public disruption.

Benefits include:

  • When laid in conjunction with the main surface dressing scheme, it reduces public disruption, traffic management costs and the need for road opening notices.
  • A much faster and more cost-effective alternative to pre-patching.
  • The increased bitumen levels provide improved waterproofing and flexibility to the carriageway surface, especially during the winter months.
  • Note – this process is not suitable for high stress points, e.g. hills, bends, junctions.
