Whereas snow maintenance managers have traditionally deiced pavement surfaces after a snow storm, anti-icing requires advance planning before the storm arrives. If managers use an organized and systematic approach in their anti-icing programs, roads will be in the safest possible condition for winter storms. The program must consist of well-timed applications of a liquid deicer as well as good judgment in decision making. Anti-icing programs are best suited for roadways requiring a high level of service as the preventative features of the operations are most congruent with service levels requiring more frequent winter maintenance.
There are numerous benefits believed to be associated with the use of anti-icing; such benefits include reduced maintenance costs and improved motor safety. Anti-icing programs are also thought to reduce the number of road closures and crash frequency. The decrease in automobile crashes leads to a decrease in insurance claims, injuries, and timely delays.The anti-icing program's use of liquid de-icers results in improved air quality as well as having decreased negative impact on water supplies; as compared to past methods of road treatment. Furthermore, using liquid deicers over other road treatment methods has been show to reduce negative effects on roadside trees and vegetation, making the product a good choice for protecting the environment. In general, anti-icing programs have shown advantages over rival snow management techniques in the areas of safety, mobility, productivity, and environment quality.
