When a road surface is newly laid it has an inherent skid resistance which helps prevent accidents and promotes safer roads. The skid resistance is dependent on both the micro and macro texture of the road surface. Over time, traffic and other factors cause the skid resistance to reduce through a combination of binder bleed, aggregate embedment and or polished exposed aggregate. Inadequate skid resistance will lead to higher incidences of skid related accidents.

Retexturing the worn surface will restore the road surface to the same, or better, skid resistance as when it was first laid. This ensures the best road safety conditions of the road surface. Retexturing is a vastly cheaper alternative to re-surfacing the road as well as significantly quicker and environmentally more friendly.

 

 

 

 

Benefits:

  • Restores highways, or runways, skid resistance
  • Works on concrete and asphalt surfaces
  • Improves road safety and reduces accidents
  • Cheaper and faster than resurfacing
  • Prolongs the life of the road surface
  • Environmentally friendly
  • Does not damage road markings, studs or expansion joints
  • Prolongs the functional life of surface dressing when used as a pre-treatment

Applications:

  • Restoring highways anti-skid properties
  • Removing Rubber build up from aircraft runways
  • Restoring original colour to decorative resin based surfaces
  • Ideal pre-treatment before surface dressing

Services

Shot Blast Surface Retexturing

The shot blast system can be used on all asphalt substrates. The shot is fired at an optimum velocity to abrade and reprofile the exposed aggregate. The shot is captive in the system, being collected with dust/debris. The collected material is sorted and the shot is recycled and reused. The dust/debris which is removed (a mixture of bitumen, aggregate fines and a small amount of iron) is classified under the Waste Management Regulations 1994 as non-hazardous, the same classification as asphalt arisings and is fully recycled by local asphalt plants or local recycling companies.

The retexturing process is managed from the cab, using a touch screen controlled computerised system, that offers a high degree of accuracy. This ensures other road assets such as road markings, studs, and expansion joints are avoided and do not require replacement. The skilled operatives are able to make fine adjustments to ensure that the process runs efficiently at all times.

Hydrotexture Water Retexture

The Hydrotexture technique delivers water at high pressure to scour excess binder and detritus from the road surface, thus restoring macro-texture and exposing micro-texture. The system is purpose-built to allow pressure and flow rate to be adjusted in order to achieve the optimum result for each site.

The Hydrotexture system recovers the resulting mix of water and detritus using powerful suction, thereby eliminating the need for a separate road sweeper.

Captive Shot Blast Retexturing for Concrete

Textureblast has adapted its captive shot blast retexturing system for use on concrete surfaces. By varying the speed of the vehicle, increasing the size of the shot and the velocity at which it is propelled, a substantial increase in both micro-texture and macro-texture can be achieved.

Why two systems?

A choice of techniques is available to suit the substrate condition and the client’s objective.

Hydrotexturing will improve macro and micro-texture but is usually selected, with variable flow rates, for the optimum removal of excess binder, whilst captive shot blasting will restore both macro and micro-texture.

Good Asset Management

Retexturing of a road can either be carried out across the full width of the carriageway or in the vehicle wheel tracks only, as required by the client.

All sites are pre-inspected to ensure that they are suitable. The most appropriate system is always recommended to ensure that the client achieves the best outcome and value for money.

In accordance with best practice under the asset management approach, texture depth and skid resistance values are measured both before and after treatment using a Findlay Irvine micro GripTester and a full report is then produced for the client.
