Asfaltia produces bituminous mixtures and provides maintenance services and the conservation of public works.
Road surfaces are made up of a series of layers placed horizontally on the ground, with two main functions:
- Resistance: must be able to sufficiently cushion the loads so that the surface can withstand them.
- Provide a comfortable, safe driving surface.
The surface of any road is made up of layers of bituminous mixture. A bituminous mix is defined as the combination of a hydrocarbon binder mechanism, aggregates, mineral powder and finally 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 their manufacturing temperature, 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 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 situation that arises. For example, a bituminous mixture specific to road tunnels, additives to improve its resistance to fire, bio-blends etc…
In addition to the bituminous mixtures produced at their five asphalt plants in The Basque Country and in Castilla and León, Asfaltia also offers maintenance and conservation services.
