STUDIES ON SOIL-AGGREGATE-SODIUM CHLORIDESTABILIZED ROADS IN FRANKLIN COUNTY, IOWA

Sodium chloride-stabilized roads in Franklin County, Iowa were studied to gain a better insight into the time-rate of material loss from the surface. The roads were located in the same general area and were constructed of materials from the same sources so that the main variable was the duration of service. The thickness of the soil-aggregate-sodium chloride surface courses and the amount of float material on the surface of the road were determined. The float material was tested in the laboratory to study any gradation changes that might have occurred following displacement from the intact surface course. The component materials of the soil-aggregate mix were tested in the laboratory to determine what changes in physical properties could be attributed to the addition of sodium chloride. The results of these investigations show that the thickness of the surface course decreases and the amount of float material increases as the period of use increases. These tests also show that the silt-clay content of the float material is less than in the soil-aggregate surface course. The addition of sodium chloride to the soil-aggregate mix caused no noticeable changes in the Atterberg limits of the mix, whereas significant changes in the Atterberg limits of the soil component were noted after the addition of sodium chloride. /Author/
