Every year there are huge amounts of vehicle tires that are worn out or suffer damage beyond repair. Despite of ending up in stockpiles or landfills, scrap tyres can be recycled and processed into a wide range of useful products. One of them is recycled into crumb rubber and then made into wet pour rubber crumb surfacing.
What is Wet Pour Rubber Crumb Surfacing?
Wet pour safety surfacing is a continuous, porous material made by mixing rubber crumb with a polyurethane resin on site and laid on an existing suitable or specially prepared base. It is a two-layer system including the base layer (shock pad layer) and a top layer(wearing course layer). The rubber of the base layer is different from that of the top layer. The base layer is varied in depth depending on the use of the area, while the top layer determines the color and pattern design of the surfacing.
The crumb rubber is available in a wide range of colors so that it is highly decorative and can also be used for demarcation of different areas of child play kits. The crumb rubber can also be incorporated into different pictures, logos and other graphics.
Advantage of Rubber Crumb Safety Surface
Rubber crumb surfaces are strong and durable, slip resistant, and suitable in all weathers. Due to the highly impact absorbent properties of rubber crumb, rubber crumb surfaces can be applied to almost any area where there is a risk of falling, especially where young children or elderly people are present. The greater the depth of the cushioning, the more impact can be absorbed.
Application of Wet Pour Safety Surfacing
Rubber surfacing can be used in playgrounds, nurseries, school sports areas, athletic tracks, tennis & basketball courts, golf tees and golf course pathways, parks, garden paths, boat deck surfaces, swimming pool surrounds, pubs, garages, driveways, sidewalks, patios, etc.
Recycling Tires into Crumb Rubber
Scrap tires are cut by a ring cutter into two halves, one is with the steel wire and the other is not. The part that has the steel wire is processed by the steel wire separator which separates the steel wires from the tyre. The other part is cut into strips by the strip cutter. Then the strips are cut by the block cutter into blocks. The rubber blocks are then put through a grinder which reduces them into tiny granules known as crumb rubber. After vibration separation and magnetic separation, the steel wire are removed and the crumb rubber that does not meet the size requirement are reground.
