Bitumens with end of life crumb rubber (PNFU)

Crumb rubber modified bitumens (CRMB)

Repsol, as part of its commitment to the development of eco-friendly technology, has developed an innovative product from end of life crumb rubber to improve bitumen performance
The technical advantages of bitumens with end of life crumb rubber (PNFU, from the National End-of-Life Tire Program) can be added to the qualities that make these binders eco-friendly. Using our own technology, at Repsol we offer a solution to a current problem: the elimination of end-of-life tires.
 
The stability and homogeneity of the final product has been achieved through the use of a specific product and to the use of selected bitumens.
 
This technique results in the following range of products:
 
  • Bitumens Improved with Rubber
  • Bitumens Improved with Rubber
  • High-Performance Modified Bitumens with Rubber
  • High-Performance Modified Bitumens with Rubber

Bitumens improved with rubber are mainly applied to intermediate bases and can also be used with conventional mixtures for heavy traffic categories, T1 to T4.
