Asphalt bitumens

Asphalt bitumens are binders from the distillation of crude oil. They are characterized by their viscoelastic performance which depends on temperature and their high chemical stability. They are also called penetration bitumens due to the fact that this property is used to classify them.

Uses and characteristics

Uses and characteristics

Bitumen is the component that binds and gives cohesion to bituminous mixtures and is mainly responsible for their properties. Its consistency can be modified by applying more or less temperature, which allows their easy handling, enveloping of the aggregates, compacting of the mixtures and their adequate performance at service temperatures. Asphalt bitumens mainly have two fields of application: the road and the industrial environment.

Roads

  • Conventional hot bituminous mixtures
  • Polymer-modified bitumens
  • Crumb rubber-modified bitumens
  • Fuel-resistant bitumens
  • Multigrade bitumens
  • Emulsions (conventional and modified)
Industrial applications

  • Emulsions and mastics for industrial waterproofing and paving 
  • Asphalt sheets
  • Pipe coating
  • Hydraulic works
  • Sealing of joints
  • Asphalt paints, etc.
The conventional bitumens most widely used in Spain are those with 35/50 and 50/70 penetration, which are used to manufacture conventional bituminous mixtures. This is due mainly to climatic reasons, since type of climate is one of the main conditioning factors when using one or other type of bituminous binder.

For use in road construction, five types of asphalt bitumens are differentiated in accordance with their penetration. The most widely used in Spain are those with 35/50 and 50/70 penetration, which are used to manufacture conventional bituminous mixtures. This is due mainly to climatic reasons, since type of climate is one of the main conditioning factors when using one or other type of bituminous binder.

Repsol's bitumens improved with rubber actively contribute to increase road quality and safety

Repsol bitumens improved with rubber

Repsol uses proprietary technology to develop so-called "green asphalts" in which the base bitumen is mixed with crumb rubber under certain conditions. Asphalt mixtures for road surfaces manufactured using these rubber bitumens have significant technical advantages such as: lower acoustic impact on reducing the noise levels produced by wheeled traffic and greater adherence. 

They also contribute to solving the major environmental problem posed by the accumulation of this waste due to the reuse of more than 10,000 tons of end-of-life tires annually. In short, the use of these bitumens achieves more efficient and eco-friendly asphalt mixtures.
