Calcium chloride (cacl2) is used to clear snow from hill station due to the following reason 
1- it depress the freezing point of ice . 
2- when calcium chloride is added , there is a lowering of freezing point of the salt water to -29 degree celsius. 
3- hence , it doesnot melt the ice , but lower its freezing point only .. 
DUE TO THE ABOVE REASON ITS USED FOR CLEARING SNOW IN HILL STATIONS . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
