Rubberized Asphalt By: Gabriel Ortiz MEEN 3344
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.
