HOW ASPHALT is MADE with MILLIONS of OLD TIRES

For decades, used tires were one of the most polluting types of waste on the planet, capable of taking thousands of years to degrade and causing serious environmental problems. However, what was once considered trash has now become a key resource for modern engineering. Millions of discarded tires are being transformed into an innovative material that is changing the way roads are built around the world. The process begins with the collection and recycling of end-of-life tires, where steel and other components are separated to obtain high-quality shredded rubber. This material goes through cleaning, drying, and thermal treatment stages before being mixed with hot bitumen. The result is rubber-modified asphalt that offers greater elasticity, increased resistance to wear, and a significant reduction in traffic noise. In addition to improving road performance, rubberized asphalt represents a sustainable solution to a global environmental problem. A single kilometer of roadway can reuse thousands of tires, reducing landfills and pollution. This circular economy model shows how technology and engineering can transform hazardous waste into more durable, efficient, and environmentally friendly infrastructure.
