• Abstract:
  A research project was initiated to evaluate the performance and cost effectiveness of a proprietary, pre-blended, ; roadway-deicing chemical on New Hampshire highways. The evaluated material is a patented blend of sodium chloride, liquid ; magnesium chloride, and cane molasses. The manufacturer reported that the treated salt provided value greater than that of ; conventional sodium chloride because a smaller quantity was needed to obtain the same result. This report documents the New ; Hampshire Department of Transportation’s (NHDOT) evaluation of the treated salt material and provides a cost comparison ; between the test material and straight sodium chloride under normal snow removal and ice control conditions during the 2003- ; 2004 winter season. ; Two NHDOT-maintained roadways were chosen for the evaluation. Each test site was divided into a test section that ; was treated with the test material, and a control section that was treated with conventional sodium chloride. Both materials were ; applied to the roadway during normal snow removal operations by the same operators using the same NHDOT plow trucks ; equipped with conventional sand/salt spreader bodies. Standard NHDOT snow removal and ice control procedures were ; followed. Test sections were rotated on a monthly basis to minimize variability. ; Although the quantity of treated salt required during the study was less than that of the straight sodium chloride, the ; reduction of material was not enough to offset the higher unit cost of the treated salt. On average, the treated salt cost 27 percent ; more to use than sodium chloride during the test period. ; It is noted that subsequent to the completion of the field phase of this project, the manufacturer reportedly reformulated ; the product and released what is referred to as an enhanced deicer. It is believed that the product evaluated during this research is ; no longer marketed.
