ON-VEHICLE TYPE CONTINUOUS SALT-CONCENTRATION MEASURING SYSTEM FOR EFFICIENT WINTER ROAD MANAGEMENT

Concentration of deicing chemicals (salt) sprinkled over road surfaces in winter decreases as the chemical scatters from passing vehicles and dilutes from precipitation. As the concentration of deicers decreases, the freeze-preventing effect decreases. To determine whether applied deicing chemicals are still effective or whether additional applications are required, it is necessary to measure the actual concentration of salt remaining on the road surface. Conventional practice of salt concentration measurement is for field measurement personnel to make manual measurement on the road surface. This point-to-point measurement method does not lend itself to longitudinally continuous and two-dimensional measurement of salt concentration required for road management and is dangerous because manual measurement needs to be made on the road surface. The on-vehicle type continuous salt-concentration measuring system--designed to solve these problems--makes it possible to measure salt concentration from a moving vehicle. Tests confirmed that the system is capable of safe and quick measurement of salt concentration. The system, which enables management of salt concentration on the entire road surface, is expected to improve the efficiency of deicing chemical application.
