Abstract
The correct disposal of tires is a major concern for the environment. A part of the waste is used to manufacture rubber asphalt, providing environmental, technical, and economic advantages. In the present work, it was identified that the permanent deformation at 60 °C in 10,000 cycles for CAP 50/70 (traditional asphalt) is 4.7%, while rubber asphalt is 2.5%. In addition, the permanent deformation at 60 °C in 30,000 cycles for CAP 50/70 is 6.2%, and for rubber asphalt, it is 3.2%. Thus, the pavement with rubber asphalt is more durable compared to the pavement with CAP 50/70. So, even though rubber asphalt is a little more expensive, in the end, it becomes more economical because it has greater durability. Moreover, over the years the CAP 50/70 will need more maintenance, while rubber asphalt promises a much lower amount of maintenance.
