Title:

Reducing Salt Consumption by using Road Weather Information System and Mesan Data

Abstract:

This paper describes a new salt index developed by the Swedish National Road Administration (SNRA). The salt index is based on data from SNRA's 700 road weather information system (RWIS) stations as well as on data provided by the Swedish Meteorological and Hydrological Institute (SMHI) and on the total amount of salt. SNRA uses RWIS data for information on air and road surface temperatures, humidity, wind, and type of precipitation and SMHI data for the amount of precipitation. In calculating the salt index, the length of road treated with salt, type of road, and guidelines for salt are used. A salt index of 1.0 indicates that the contractor (or county, regional, or national road manager) has used the optimum salt dosage.
