This review was initiated to ascertain the state-of-the-art of highway deicing and to furnish information and suggestions for use in planning and initiating research in this problem area.

This concise report summarizes the results of the by: Our survey of deicer users in indicated that solid NaCl was most frequently used, followed by abrasives, then MgCl2, agricultural-byproduct-based (agr-based) 2, calcium chloride (CaCl2), and then other deicers (Table 6).

It is interesting to note that less than 25% of the survey respondents used alternative deicers such as acetates and Cited by: CURRENT DEICING PRACTICES AND ALTERNATIVE DEICING MATERIALS This chapter describes current MDOT deicing practices and materials (primarily road salt and sand) and presents information on several materials thought to merit study as potential alternatives to the extensive use of road salt: CMA (calcium magnesium acetate), calcium chloride, CG "Survey of Alternatives to the Use of Chlorides for Highway Deicing".

Federal Highway Administration, Offices of Research and Development, Rep. FHWA-RD, Geothermal Energy for. ABSTRACT Deicing agents for removal of Ice and snow from highways and streets are essential to wintertime road maintenance In most areas of the U.S.

Due to the ever-Increasing use of highway delclng materials, there has been growing concern as to environmental effects resulting from these practices. Crumbling was often accompanied by brown discoloration. Severity and type of deterioration depended chiefly on deicer cation and experimetnal conditions.

Magnesium chloride was most destructive. Calcium chloride was next, and sodium chloride was relatively benign except under freeze/thaw cycling in M NaCl, and high temperature wet/dry cycling. National Scale. Individual water-quality samples for chloride in 17 major metropolitan areas around the country were retrieved from NWIS, the U.S.

Geological Survey national water-quality database (Figure (Figure1). 1).Candidate streams were selected based on the latitude and longitude of the monitoring location and its proximity to major urban land-use by: The guidance presented in this section and in Appendix C is based upon the results of 4 years of anti-icing field testing conducted by 15 State highway agencies and supported by the Strategic Highway Research Program (SHRP) and the Federal Highway Administration (FHWA).

manufacture, handling and use." The perfect deicing chemical does not exist at this time, however, several of the following chemicals meet at least some of the criteria. Sodium chloride is the most commonly used deicing chemical.

It is generally referred to just as "salt" although most other deicers are also, technically, salts. Physical Alternatives to Chemicals for Highway Deicing Robert R.

A study by Marquette University found that deicing roads with salt reduces accidents by 88 percent and injuries by 85 percent (Kuemmel and Hanbali, ).

than highway speeds. Do not follow the trucks too closely, as the chemicals are slightly slippery for the first 30 to 45 seconds they are on the pavement. If you must pass an anti-icing truck, do so carefully.

It is a good idea to wash your vehicle if it comes into contact with these chemicals to File Size: KB. Entry ® is the only de-icer that breaks down ice molecules — so it keeps working to temperatures as low as °F /°C. Chloride-free = better health. Entry ® keeps salt run-off out of tap water, for sodium levels that are safer for hearts and overall health.

Chloride-free =. Deicing, Plowing & Sanding Before a storm arrives or in the early stages of a storm, MDT may apply winter maintenance chemicals to roadways to prevent snow and ice pack (anti-icing).

Zenewitz and United States. On October 7,while approving a recommendation to extend the existing contract for supply of road salt for de-icing, Council requested a report back on substitutes for de-icing salt which may be in use elsewhere, along with comparative costs of using alternatives to de-icing salt.

Winsford rock salt is more than 90% pure sodium chloride, with the remaining insolubles consisting mainly of Keuper Marl, which is a layer of clay from the late Triassic or ‘Keuper’ period.

Keuper Marl has weathering properties, which give Winsford rock salt its unique. Project Objective The overall goal of this project was to evaluate potassium acetate (KA) and sodium acetate/formate blend deicers (or possibly potassium formate) as alternative anti-icing and deicing compounds relative to NaCl salt-sand mixtures and MgCl2 (baseline deicers) based on various criteria specified by the Colorado Department of Transportation (CDOT).

The concern for deicing salt is that it may cause the corrosion of some metal surfaces. Mixing the salt with gravel and sand will serve to limit this effect. Because sodium chloride is much more widely available than alternatives, it remains the favorite deicing material for.

Alternative Highway Deicing Chemicals* Dr. Stanley A. Dunn and Dr. Roy U. Schenk Bjorksten Research Laboratories, Inc. Madison, Wisconsin A search has been made for road deicing chemi-cals to replace sodium chloride (NaCl).

The impetus for this search stems from the numerous drawbacks associated with the current extensive.

Third party providers may use all. deicing practices on the new Interstate Highway System.3 By the s, road salt deicing had replaced or augmented other techniques in nearly all deicing appli-cations.3 Inroadway deicing accounted for 45% of total salt consumed1.

Data source: U.S. Geological Survey Salt The most common deicing method is the use of sodium chloride in. Use alternative deicers: in areas designated as too sensitive for road salt but also with high risk safety concern, use alternative deicers with fewer negative impacts.

Abrasives such as sand can also be used in sensitive areas, though the impacts of sand should also be evaluated. Trucks can have multiple bins and can switch de-icing types.The dissolved major and trace constituents of deicing chemicals as a source of constituents in highway runoff must be quantified for interpretive studies of highway runoff and its effects on surface water and groundwater.

Dissolved constituents of the deicing chemicals-sodium chloride, calcium chloride, and premix (a mixture of sodium and calcium chloride)-were determined by analysis of salt.Deicing a large commercial aircraft typically consumes between US gallons (1, L) and 1, US gallons (3, L) of diluted fluid.

The cost of fluid varies widely due to market conditions. The amount deicing service companies charge end users is generally in the range of US$8 to US$12 per diluted gallon (US$ to US$ per liter).
