The article describes the actual in-field performance of CMA (calcium magnesium acetate) vs road salt performance as documented by the Nevada Department of Transportation and Caltrans (California Department of Transportation). The Univresity of Nevada performed data collection to determine and document the effectiveness of CMA relative to NDOT's standard practices using salt. The test section which consisted of 12.5 miles of 2-lane highway on SRs 28 and 431, and the details of the testing are summarized. It was found that although CMA did work as snow and ice control deicing chemical, the timing of the initial application of CMA was critical. The spherical shape and low density of the CMA was a drawback, and it would create an 'oatmeal mush' which had to be removed mechanically. These and other findings are noted.
