Circular salt, for sustainable winter road maintenance

Purpose and goal

** Denna text är maskinöversatt ** The project aims to perform and validate the use of fine-grained circular salt with a focus on: The process of making brine from circular salt. Scattering of fine-grained circular salt. Validation and evaluation of a method for winter road maintenance with circular salt. Identify necessary adaptations in eligibility requirements and regulations linked to Road maintenance contracts. Cost/benefit analysis when switching to circular salt.

Expected effects and result

** Denna text är maskinöversatt ** The demonstration is expected to provide a prerequisite for creating a road maintenance with minimal climate impact by showing that local use of circular salt is possible. A demand is created for circular salt in road maintenance. The project will provide a knowledge base to be able to set eligibility requirements in procurements that lead to a competitive market. Create new jobs in Sweden. Reduce dependence on foreign suppliers. Reduce CO2´s footprint in road maintenance.

Planned approach and implementation

** Denna text är maskinöversatt ** The demonstration, which will last for two winters, will begin by adapting the machines and equipment that will be used for spreading circular salt. The effect of the salt will then be evaluated by measuring road friction using connected vehicles in order to validate and evaluate how efficient the circular salt is for anti-slip. As an important part of the project, we will analyze and identify adaptations that must be implemented in regulations and eligibility requirements to create the conditions for implementation.
