Friction is very important to people – without it, for example, we could not walk or even crawl, so why did it take so long for the study of the relationship that exist between deicers and snowy/icy roads. Scientists at EnviroTech Services have been studying this relationship and with the help of modern road sensors have developed a test that shows the effect on friction for deicers. A little history on friction and tires, roads and now deicers follows.
