SKIDABRADER SHOTBLASTING TECHNOLOGY

MACRO TEXTURE


Macro-texture is the space or voids between the aggregate particles. The texture depth / macro texture of an asphalt pavement surface will normally be between 1.0mm to 1.5mms.It is this macrotexture which allows the water to drain away from the surface and greatly contributes to skid resistance in wet conditions. Shot blasting is a very cost effective, environmentally friendly and high performance technology for reducing the
danger of slippery highways & runways. It will remove rubber deposits and will bring the surface macrotexture back to that of the aggregates ability.

MICRO TEXTURE


Micro-texture is the fine component of surface texture formed by the tiny interstices on the surface of the aggregate particles. It is the main contributor to providing grip or skid resistance with the tire, particularly at low speeds. Micro-texture is measured by PSV using the British Pendulum Tester or by mobile methods such as the Griptester or SCRIM. Shot blasting is the only technology that will restore Micro-Texture values to pavement surfaces. Improvement of Micro texture with the shot blasting process is extremely effective. It will in all cases bring back the full benefit of the PSV of the aggregate as per its original properties.

WHERE CAN SHOT BLASTING BE USED?
 

  • To clean and prepare surfaces | such as steel, concrete and asphalt.

  • To remove top layers | like paint and epoxy.

  • To remove markings & rubber | from highways, runways, industrial floors and more.

  • To improve skid resistance | on surfaces such as sidewalks, bike paths, roads and runways.

  • To generate optical and aesthetics effects | on surfaces like roads, highways and runways.

Blastrac closed circuit media blasting machines throw a large amount of steel abrasive media by centrifugal force at the surface. After the steel abrasive hits the surface, the shot blaster recycles the media. Dust and contaminants are removed by an air wash separator and are removed to a dedicated Blastrac dust collector. This makes the process almost dust-free in operation. Blasting with steel shot is the most environmentally friendly abrasive blasting method there is, because there is no use of chemical products and no waste of valuable drinking water.
