Maintaining roads in good condition to ensure safety is one of ACCIONA’s lines of activity. The extreme conditions that occur in the cold winter months mean that special care is taken so that roads can be used under the best possible conditions.

The use of salt and brine to prevent the formation of ice is the most common treatment, although it is very harmful to the environment in the places where it is deposited, and it leads to later deterioration of the road surface.

In this respect, we sense a lack of awareness among both ordinary citizens and professionals about the indiscriminate use of salt to melt ice. We offer our services to find solutions that create awareness, optimise the distribution of salt, or replace it as the only way to deal with the hazardous road conditions in  winter.

Salt is the main element used to avoid ice and snow on roads. However, the conditions for spreading it are stipulated on the basis of ambient temperature, to avoid any risk to drivers. This means that it is essential to calculate the quantity of salt or brine applied, and where it is necessary, as well as calculating the amount that remains on the road surface after the last application to optimise its distribution and avoid unnecessary deposits.

Progress in sensors and portable meteorological stations leads us to apply improvements in the area of winter road maintenance, both in economic and environmental terms.

In ACCIONA we are open to suggestions, from the replacement of salt and brine to the detection of the presence of melting liquids on the roadway and the optimization of their distribution, with the aim of setting up a pilot project to co-create a product or service.
