Binder reliability

At Repsol we solve the problem of adhesiveness in mixtures of certain types of aggregates using bitumens. We have developed a broad range of additives which, together with the adequate bitumens, guarantee reliable aggregate-binder performance.

Properties and applications

The additives used promote adhesiveness, improve the chemical reaction between the aggregate and the bitumen, provide mixtures with greater durability, less aging, and greater ease of spreading of the binder over the aggregate surface.

Some of the main characteristics are as follows:
 
  • They provide the necessary cohesion in hot bituminous mixtures.
  • It broadens the range of aggregates to be used.
  • It reduces the use of addition fillers and recovery fillers can be used in many cases.
