SNOW AND ICE PROPERTIES PERTINENT TO WINTER HIGHWAY MAINTENANCE

STUDIES WERE MADE OF THE MECHANICAL AND THERMAL PROPERTIES OF SNOW AND ICE. PROPERTIES MEASURED INCLUDED THE STRENGTH, SPECIFIC HEAT AND THERMAL CONDUCTIVITY OF SNOW, AND THE STRENGTH AND FORCE OF ADHESION OF ICE. PHASE TRANSITIONS AND THE MECHANISMS OF ICE FORMATION ON PAVEMENTS ARE DESCRIBED. THE PROPERTIES OF SNOW IMPORTANT TO HIGHWAY MAINTENANCE ENGINEERS ARE DENSITY, TEMPERATURE, HARDNESS AND WATER CONTENT. METHODS AND EQUIPMENT FOR MEASURING THESE PROPERTIES ARE DESCRIBED. SINCE THE DENSITY OF SNOW INCREASES WITH TIME, EXTRA WORK CAN BE SAVED BY REMOVING SNOW DURING OR IMMEDIATELY AFTER A SNOWFALL.
