Use of Chemical Admixtures to Increase the Effectiveness of Snow and Ice Removal

项目名称：	Use of Chemical Admixtures to Increase the Effectiveness of Snow and Ice Removal
摘要：	Snow and ice removal can be a large expenditure during the winter months. With the increase in traffic volumes, winter weather events have a more serious impact on what is considered to be necessary and efficient movement of people and goods, reducing the costs associated with snow and ice prevention and removal would be very beneficial to the Department. There are products on the market now that boast longer working times, lower working temperatures, a less-corrosive formula and that are safer for the environment when compared to typical rock salt. Some of the Department's maintenance yards already use some sort of pre-wetting chemical for their sand/salt mixtures, but there are newer products out there that are made with sugars and are safer for the environment. Other cities and states are already using some of these products to reduce cost and be more environmentally conscious. Using a highly concentrated mixture of salt water (salt brine) has also been an option for anti-icing applications for some time. Salt brine has a benefit over rock salt because it will stick to the roadway, allowing it to work longer without being scattered by vehicles. Some of the Districts in the state have started using salt brine for anti-icing operations to keep the snow and ice from sticking to the pavement to begin with, allowing for easier removal with plows. Also, the Department's ability to view remote areas during winter weather events is limited. Adding weather monitoring systems to more remote areas of the state allows Department personnel the ability to more effectively utilize their resources. Managers will know what kind of equipment to send to these areas if they know what they are facing before leaving the maintenance yard.
