Blastrac scarifiers and shot blasters are the best way to remove line markings, rubber skid marks and other contaminants from asphalt and concrete. They can also be used to reduce slipperiness by retexturing the surface to increase friction. All this is done without damaging the supporting structure of the surface.
In the past Blastrac has received numerous requests to develop a fast and effective solution for the removal of existing pavement line markings. Road, highway and airfield maintenance contractors worldwide are searching for environmentally friendly and mobile machines to remove markings from concrete or asphalt surfaces. Both Blastrac shot blasters and scarifiers can be used to remove markings from surfaces of roads, highways, cycling paths, parking garages, airport aprons, runways and more.
- Scarifying machines are suitable for the removal of thick and elastic materials such as thermoplastic.
- Shot blasting systems are suitable for the removal of thinly painted road marking lines while in-depth cleaning between the aggregates. For the bigger shot blasters we have designed blast pattern reducers to reduce the width of the blast mouth.
Rubber & Contaminants Removal
Aquaplaning on roads and airfields is big danger. Over a period of time and depending on the type of covering, aggregate, and the frequency of traffic, rubber marks will gradually make the aggregate smooth and eliminate the micro texture. Soiled surfaces will eliminate the macro roughness. Without macro texture the covering no longer helps to drain the water and the film of water that then appears on the surface is responsible for aquaplaning.
- Blastrac shot blasting systems are a cost effective, environmentally friendly and safe technology for the removal of rubber and contaminants.
Improving Skid Resistance
In order to reduce slipperiness on roads, highways and airfields the roughness and skid resistance has to be upgraded to its original state. Skid resistance needs to be improved on asphalt and concrete surfaces which have become polished by traffic (either by cars or planes) or new surfaces which have a coating of bitumen binder over the aggregate particles.
- Blastrac shot blasters are able to retexture roads, highways, airport aprons and runways on both macro and microstructure level.
Asphalt & Concrete Layer Removal / Pavement Milling
Removing a thick layer of asphalt or concrete from road, highway or airfield surfaces has several purposes such as the prevention of ravelling (where aggregate becomes separated from the binder and loose from the surface) and the removal of bumps and road ruts by levelling the surface.
All Blastrac scarifiers can be used for the removal of surface dressings, thin overlayers and a few millimetres of asphalt and concrete surfaces. They have been specifically designed to have the maximum amount of weight centered above the drum shaft. Depending on the jobsize you can choose between a medium size scarifyer or for the large model. Our scarifiers and milling machines are available in either electric or petrol versions.
