Huntington Beach, California -- Two cities in California are collaborating to pave â€œgreen roadsâ€ using rubberised asphalt concrete (RAC). With help from a Department of Resources Recycling and Recovery (CalRecycle) grant, Garfield Avenue repairs will use a pavement that contains ground waste tyres laid over recycled pavement.
RAC is a paving material composed of ground tyre rubber, asphalt, and other aggregates. RAC is more durable, up to 85 percent quieter than traditional asphalt roads, and uses thousands of waste tyres per paved mile. It is also safer with better skid resistance in wet weather, and excellent color contrast that lasts, making it easier to see lines and turn lanes at night or during bad weather.
This project will use more than 3,000 waste tyres that would otherwise end up in the dump. In the past 6 years, Huntington Beach has diverted more than 200,000 waste tyres by using RAC for street repair.
