Winter
Road Treatment WHY are liquid winter road treatments beneficial? CDOT began using liquid road treatments in the winter of 1995/1996, and has been conducting research since then to determine their effectiveness, safety and efficiency. CDOT has opted to increase use of liquid road treatments as a direct result of their widespread benefits. Advantages of these solutions on roadways statewide include reduction in the use of salt and sand mixtures and improvement of road conditions during storms beyond what is possible by the use of sand and salt mixtures alone. Efficiencies in costs, and reductions in lives lost and winter road accidents, along with increases in driving safety, road navigability and environmental safety have made liquid road treatments the product of choice. There are numerous benefits to using liquid anti-icer and de-icer techniques. Since CDOT began using these products, they have reduced the consumption of sand used for winter road treatment in Colorado by 23%. This results in cleaner air and vastly reduced PM10 (particulate matter contributing to Colorado's "brown cloud" effect). Use of these products has clearly helped Colorado meet air quality standards. What's more, research into the use of liquid anti-icers and de-icers indicates that they have less negative impact on highway bridge decks, trees and vegetation, and water supply than any other method of winter road treatment utilized in the past. Liquid anti-icers and de-icers are the best products available for protecting many environmental resources. Since increasing use of liquid anti-icing and de-icing products, there has been a significant reduction in the number of winter days that state highways must be closed in Colorado. For example, in the winter of 1994-95 before liquid de-icers were used on the I-70 corridor west of Denver, the highway had to be closed 35 times due to adverse road conditions between Denver and Vail. The following winter, 1995-96, with the use of liquid de-icers, there were only 12 times the highway had to be closed. Since then, there has been an average of 13 closures per winter on I-70 west. Liquid anti-icing and de-icing technology has resulted in cost savings for the state, taxpayers, consumers and corporations. Money has been saved due to reduced wage loss due to tardiness and absenteeism, and reduced production and delivery losses that can occur during winter storms. Lives have been saved by reduced accidents and reduced response time to medical emergency Snow, ice and slush related accidents have also been drastically reduced statewide since the winter of 1995/1996 when CDOT began widely using liquid anti-icers and de-icers. Such reductions include a 76% reduction on I-70 west of Glenwood Springs in South Canyon, a 53% reduction on I-70 in the Vail area, a 89% reduction on SH 82 near Basalt, a 53% reduction on I-25 at the Mousetrap and a 64% reduction on I-70 at the Mousetrap. |
