roads

Roads are one of the most essential infrastructures used by society throughout history. It is undoubtedly the infrastructure that best penetrates the territory. Thanks to it, the different urban, industrial and rural centres remain connected, creating commercial, social, political and cultural links.

It is a versatile land transport infrastructure that can adapt to the territory’s characteristics where it is implemented, while transforming it, an essential element for sustainable development. .

Currently, roads can be classified into motorways and motorways (high-capacity roads), conventional roads and multi-lane roads.

From the original Roman road to today’s incipient smart roads, road construction has evolved dramatically, continually adapting to the technology, machinery and materials available at any given time. Throughout history, road construction companies have transformed the industry through constant innovation.

Building and innovating road networks that bring people together

The road of the future will be smart, efficient, sustainable and safe. Their construction will become increasingly technological, from the application of BIM and digital twin technologies in their design and construction to the monitoring and use of artificial intelligence for their operation and conservation to the development of new sustainable and more resistant building materials. Another significant aspect will be the implementation of connectivity between infrastructure, vehicles and drivers, all aimed at making the road safer and climate-neutral through technological innovation and the circular economy.

Once constructed, the maintenance and upkeep of roads, expressways, and highways begins—a process that is essential for extending the infrastructure’s service life and ensuring safety and traffic flow. Sando Conservación y Energía is the specialized division of Sando that carries out these activities across the country.

Since Sando Infraestructuras y Proyectos began operations as a road construction company in 1974, road construction has evolved significantly. Today’s roads are much more sustainable and safer. Moreover, they have been adapted to the characteristics of the vehicles on them and the needs of road users. Thanks to the experience acquired throughout its years of activity, Sando has the knowledge and resources necessary to complete construction projects for the roads of the future successfully.

Sando has highly qualified personnel in this type of infrastructure and specific machinery for road construction. Sando has the essential road construction machinery for developing its activity, such as earthmoving and bituminous paving machinery. In addition, it also owns machines for conservation, aggregate, hot mix asphalt (HBC) and concrete manufacturing plants, which allows it to undertake projects with its resources.

In this regard, Sando Infraestructuras y Proyectos is a road construction company with extensive experience in building all types of land transportation routes. Throughout almost 50 years, this company has developed projects for conventional roads, motorways, and highways throughout Spain. It also belongs to the Spanish road construction companies with experience in international projects. Sando has carried out some projects: the A-23 Dual Carriageway, the A-4 Dual Carriageway, the Jerez Los Barrios Dual Carriageway, the Alozaina Road, and the A-68 Dual Carriageway.
