BASE STABILIZATION WITH CUT-BACK ASPHALT AND CHLORIDES, NOBLES COUNTY

THIS STUDY WAS UNDERTAKEN IN 1960 TO INVESTIGATE THE FEASIBILITY OF STABILIZING A LOCAL AGGREGATE BY THE USE OF CUTBACK ASPHALT, SODIUM CHLORIDE, AND CALCIUM CHLORIDE. FIVE TEST SECTIONS, EACH APPROXIMATELY ONE NILE IN LENGTH, WERE CONSTRUCTED IN WHICH THE BASE OR SUBBASE WAS TREATED WITH ONE OF THESE MATERIALS. AN UNTREATED SECTION WAS ALSO INCLUDED FOR CONTROL. THE PROJECT IS LOCATED IN SOUTHWESTERN MINNESOTA ON A COUNTY ROAD WITH A LOW TRAFFIC VOLUME. THE MERITS OF USING THE VARIOUS ADDITIVES WERE EVALUATED BY VISUAL OBSERVATIONS AND FIELD AND LABORATORY TESTS BOTH DURING CONSTRUCTION AND THE FIVE YEAR PERIOD WHICH FOLLOWED. AT THE END OF THIS PERIOD, MOST OF THE SALT HAD MIGRATED OUT OF THE ROADWAY STRUCTURE. NONE OF THE ADDITIVES INVESTIGATED PROVIDED ANY DEFINITE BENEFITS IN EXPEDITING CONSTRUCTION OR IN IMPROVING THE PERFORMANCE OF THE VARIOUS SECTIONS. /AUTHOR/
