The usage of deicing salts, primarily rock salt, for snow and ice control on Michigan's state trunkline system has been on the increase, as it has in other north central states, since the early 1960’s when a. bare pavement policy began to be implemented. Twenty years ago we were using about 100, 000 tons of rock salt on the state trunklines, whereas in each of the last 10 years, we have used between 300 and 345, 000 tons on about 9,450 miles of state routes. During the winter of 1978-79 the total rate of salt application varied from about 17 tons per two-lane mile in the northern part of the state to a high of 42 tons per two-lane mile in the Detroit metropolitan, four county area.
