How is it Made? A tire is shredded to loosen the steel belting. A magnet removes steel from the rubber The rubber pieces are grinded down into small pellets. 20% of tire rubber which is blended with an 80% liquid asphalt mixture.
What are the Benefits? Great place to dispose of tires. Creates a quiet ride about 75% decrease in noise. Heat-efficient porous top layer cools quickly. Safer than concrete, it allows water to travel through it and be pushed off to the sides of the road, decreasing hydroplaning. Reduced rutting when compared to regular asphalt. More skid resistant.
Disadvantages Cost Heat sensitive - It must be applied on surfaces ranging from 85-145 degrees Fahrenheit. It is a coating of only a few inches so a base material of asphalt or concrete is still required.
