Tyre recycling is the process of converting scrap or unwanted tyres into materials that can be used in new products. Scrap tyres are usually subject to recycling when they are no longer functional due to wear or damage and cannot be re-laid or re-slotted.

According to the tire industry, tire recycling is an important success story. The asphalt industry has been a big factor in reducing the number of tires in landfills, with inventories of used tires shrinking from more than 1 billion in 1991 to just 60 million in 2017.

In 2017, ground rubber applications accounted for 25% of used tires. Floor rubber is used to make some products, but the biggest use of floor rubber is asphalt rubber, using about 220 million pounds or 12 million tires annually. The largest users of asphalt rubber are California and Arizona, followed by Florida, and usage is expected to grow in other states.

Recycled tyre rubber (RTR), derived from used tyres, has been used in asphalt by the paving industry since the 1960s. RTR has been used as a bitumen binder and bitumen mixture additive for gap gradation and open gradation of bitumen mixture and surface treatment.

Benefits of Asphalt Rubber

  • Excellent fatigue resistance improves the durability performance of the pavement.
  • Increased resistance of pavement to fatigue cracks and reflection cracks due to high volume and good elasticity.
  • Stronger low temperature flexibility reduces the temperature sensitivity of the pavement.
  • Improved road resistance to aging and oxidation because of high binder content, thick oil film and the presence of antioxidants in tires
  • Excellent resistance to permanent rutting deformation.
  • Significant reduction in road maintenance costs due to the improved durability of the road
  • The extensive use of used tires saves energy and contributes to environmental protection.
  • Carbon black in rubber enables long-term preservation of pavement black color and high contrast with markings, which improves road safety.
  • Rubber asphalt is used in asphalt mixture, due to the thin construction thickness, the construction is rapid, shortening the construction time.

What is RTR?

Recycled tire rubber is basically recycled tire rubber that is ground into very small particles and used as an asphalt modifier. The addition of ground tire rubber to asphalt helps improve rutting resistance, skid resistance, ride quality, road life and reduce road noise levels. Adding rubber to asphalt solution can delay the aging and oxidation of the resulting binder and increase pavement life by reducing brittleness and cracking.

How is RTR Made?

Tyre handling and crushing is a carefully planned and monitored process to produce a clean and highly consistent rubber material. Crumb rubber is produced by grinding rubber tires into very small particles.

In this process, the tire’s steel wire and fibers are removed. The wires are removed by magnets and the fibers by suction. To process tires using low-temperature fracture, a sharp steel knife is used to cut larger tire fragments into smaller, usually 50mm particles. These smaller pieces are then frozen and broken. According to the customer’s requirements, the rubber particles are sieved into pieces of different sizes. The resulting rubber particles are uniform in size and very clean. Automatic bagging system helps ensure proper bag weight and eliminates cross contamination.

Tire Shredder for Sale

The tire shredder is a mechanical device used to cut tyres and rubber into fine pieces or rubber powder. Whole tyres are difficult to process directly due to the steel wire and large size. It is an excellent tyre recycling pre-processing machine. Feel free to contact us for competitive tire shredder prices.
