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.
