Asphalt

Asphalt production with manufacturing systems of bituminous mixtures, environmentally friendly, for a greater energy efficiency and environmental sustainability.

Asfaltia produces a mixture of bituminous and offers maintenance services and conservations of public works.

The road surface is constituted by a set of layers placed horizontally on the ground, with two main functions:

  • Resistance must be able to sufficiently cushion the traffic so the esplanade can be supported.
  • Provide a comfortable and safe tread.

The pavement, which forms part of any road, is composed of layers of bituminous mixture. A bituminous mix is defined as the combination of a hydrocarbon binder mechanism, aggregates, mineral powder and eventually additives so that all the aggregate particles are covered with a thin film and a homogeneous binder.

At the same time bituminous mixtures can be classified according to manufacturing temperatures in cold, tepid, medium-hot and hot mixtures.

Asfaltia is committed to making sure that bituminous mixture manufacturing systems are more environmentally friendly, i.e., bituminous mixtures are made at temperatures below 100°C, with high rates of recycled materials, not only for its greater energy efficiency and environmental sustainability, but also for the health of our workers.

Furthermore, through R+D and innovation, we develop specific products for any necessary situation. For example a bituminous mixture specific to road tunnels, additive added to improve its burning behaviour, bio-blends etc...

Besides bituminous mixtures in their five asphalt plants located in Basque Country and in Castile and León, Asfaltia also offers maintenance and conservation service.
