asphalt rubber RARx

RARx additive with rubber powder

60% ELT powder in its composition

(ELT: End of Life Tires)

What is RARx?

RARx is a high-tech product made from end of life tyre powder (60% of its composition) pretreated with bitumen and other additives of mineral origin. 

RARx marks an evolution of currently existing technologies, incorporating powdered rubber from end of life tyres into asphalt mixtures.

  • The final quality of the product and the digestion of the rubber powder particles are ensured when carrying out this process at the place of origin (wet process).
  • It takes advantage of its versatility and ease of use in asphalt-mixing plants since it is incorporated into the production process of the mixes in question as an additive or an additional fine aggregate (dry process).

How do you work with RARx?

The main advantage of RARx is its ease of use in asphalt-mixing plants

  • The RARx is sent to the plant in big-bags or tankers.
  • It is stored in one of the filler silos.
  • It is dosed with the aggregates for an even distribution with them before its incorporation into the end product.

In this way, the RARx allows the manufacture of asphalt mixtures of high performances for small works or actions, without energetic extra charges for the plant of manufacture of mixtures and with the versatility of being able to execute works of great or small volume, constant or discontinuous in the time.

What are the advantages of working with RARx, additive with rubber powder?

The asphalt mixes produced with RARx have numerous advantages in different aspects, which can be summed up as follows:

Technical advantages of RARx, additive with rubber powder

  • Enables the performance of modified mixtures to be achieved
  • Prevents the spread of cracks
  • Exponential increase of life to fatigue
  • Absence of plastic deformations

Financial advantages of RARx, additive with rubber powder

  • Improves the cost compared to mixtures with modified bitumens
  • Avoids any problems on work site and allows high performance execution
  • Avoid problems with rubber bitumen, such as decantations and tank problems

Environmental and social advantages of RARx, additive with rubber powder

  • Substantial improvement of the LCA of the executed works, thus protecting the environment (LCA: Life Cycle Analysis)
  • It allows the optimization of the pavements and, therefore, a lower use of natural resources.
  • Allows the reuse of used tires.
  • Allows the manufacture of low-noise asphalt mixes
