Although rubberized asphalt was developed initially as a way to make road patches last longer, recent studies have shown that it comes with many more benefits.

Noise Reduction ? As noted in the study done in Arizona, cars produce less noise when driving on rubberized asphalt. used tyre recycling plant for sale The rubber creates a more porous and flexible road surface that dissipates the vehicle?s sound instead of reflecting it outwards the way hard surfaces do.
Greater Longevity ? One of the first properties of rubberized asphalt observed was that patches made from this type of material lasted much longer than previously used asphalt. More recent case studies on the topic show that it can last up to 50% longer and resists cracking.
More Economical ? Paving a road with rubberized asphalt requires less raw materials, as it can be thinner and still handle the same volume of traffic. The reduction in initial materials cost combined with a decrease in repairs makes rubberized concrete cheaper to build and maintain.
Increased Safety ? Rubberized asphalt is darker in color. Road markings stand out better against this dark road surface, making night driving easier. Studies have shown that the added crumb rubber gives drivers better traction and reduces skidding as well.
Environmentally Beneficial ? Using scrap tires to pave our roads is a responsible way to re-use the masses of rubber that would otherwise be discarded every year. Resurfacing a road with two-inch-thick rubberized asphalt uses 2,000 scrap tires per lane per mile. It doesn?t take a large project to make a measurable dent in our overly large sized problem. For example, California alone produces 40 million tires per year. 75% of those can be diverted away from landfills into this type of construction project.
Although most rubberized asphalt projects currently underway in the United States are taking place in warmer states, the practice is catching on elsewhere. States like Colorado and Washington are adopting the methods and techniques used elsewhere to see if they can overcome the challenges associated with mixing, laying, and compacting this material on their roads. It is only a matter of time before we are literally driving on tires wherever we go.
