Research status of road deicing salt

Abstract

The rapid development of highway construction has greatly improved socio-economic growth and people's living standards, and the safe and efficient operation of highway transportation network is the basis for ensuring the sustained growth of economy. Snow and ice on the road reduce the adhesion coefficient of vehicle tires to the road, according to relevant data, the adhesion coefficient of road surfaces with soft snow is 0.20-0.40, and the adhesion coefficient of road surfaces with compacted snow is 0.15-0.5, the adhesion coefficient of icy roads is only 1/8-1/4 of that of dry roads
