There are still more than 95 gravel roads in the county that the county maintains. When we have a very dry period in the summer months, these county maintained gravel roads might need a calcium chloride treatment applied in order to help control the dust on these roads. This application is done thru our construction operations and is usually done in late summer, early fall. The calcium chloride treatment is one of the most effective dust control agents in the industry that retains moisture for prolonged periods. It helps to hold down dust and stabilize unpaved road surfaces, creating smooth-riding roads. By maximizing compaction, calcium chloride also provides a longer lasting road saving on aggregate replacement.
