Pre-wetting road salt helps keep the salt on the road’s surface, which makes winter maintenance more efficient and cost-effective. While pre-wetting practices are used by many agencies, they have not been extensively studied.
A recent Clear Roads research project took stock of the current state of the practice for pre-wetting salt and other solid materials, capturing details on equipment, methods, materials and application rates. Researchers also compiled a list of preliminary recommendations to help agencies get the most benefit from pre-wetting and identified areas for future study.
