Additivated bituminous pavements

The challenge

Technological advances have shown that recycled materials such as the tires out of use, incorporated in bitumens, can reduce the level of loudness, increase the life of the pavement, improve the technical and economic capacity of the polymers and replace other natural minerals with recycled ones.

However, there was still a huge quantity of waste without a clear value that was being disposed in and fill that could have technical value in the face of various applications, one of them, asphalts.

The solution

To develop specific processes for obtaining additives from waste, mainly black smoke, derived from pyrolysis of different types of waste and rubber powder from tires out of use, which together allow the development of high-performance asphalt mixtures, reducing the amount of waste destined for landfill.

Innovations / improvements

• Reduction of the amount of waste going to  landfill.


• Collaboration with the circular economy.


• Increased knowledge of the use of additives from waste in high quality asphalt.


• Improvement of tires out of use recycling processes.
