This article reports on a unique collaborative project by highway authorities in Scotland, Norway, Sweden, Finland, and Iceland, which is designed to identify best winter maintenance practice. This three-year research project is called 'ROADEX' (Regional ROAD administrations Exchange of information and EXperience). ROADEX has appointed two working groups, one to examine winter maintenance and the other to investigate road condition management. Work has now been completed on the first part of the winter maintenance group project, to identify the winter maintenance methods adopted in each of the collaborating countries. The group has focused its efforts on specific problem areas, such as roads exposed to deep or drifting snow, and studied the types of equipment used to remove deep snow. Specialist equipment, such as high-speed snowblowers, is essential to keep high mountain passes open to traffic. These machines are kept near the areas that are known to be affected by deep or drifting snow. Another focus for discussion has been ice control, for which various techniques have been used. In Sweden, experiments have been conducted using 'hot grit', which is dropped from the back of a vehicle onto roads covered by sheet ice. The grit has to be very hot for it to penetrate the ice.
