A COMPARATIVE STUDY OF CALCIUM MAGNESIUM ACETATE AND ROCK SALT DURING THE WINTER OF 1986-1987

This study included a determination of the deicing effectiveness, handling and storage characteristics, and some of the environmental effects of the two chemicals. Cma was applied to a section of the queen Elizabeth way and the adjacent sections of service roads near beamsville, Ontario. The adjoining sections of freeway and service roads served as the salt control section. The cma was found to be at least as effective as salt in achieving bare pavement. It was found to be relatively more effective in longer storms and there was residual effect from one storm to another. The storage and handling characteristics of cma were comparable to those of salt. Modifications to equipment or normal maintenance operations were not required. The corrosion of the cma spreader unit was substantially less than that of the salt spreader unit. (a)
