EXPERIMENTAL FIELD PROJECT ON BITUMINOUS STABILIZATION OF SILTY SOILS

AN EXPERIMENTAL FIELD PROJECT WAS CONSTRUCTED IN SOUTHEASTERN MINNESOTA IN 1965 TO EVALUATE THE EFFECTIVENESS OF STABILIZAING THE UPPER PORTION OF A SILTY SUBGRADE WITH TWO DIFFERENT BITUMINOUS MATERIALS, RT-6 AND MC-2. THE PROJECT CONTAINED SIX SECTIONS IN WHICH THE UPPER SIX INCHES OF THE SUBGRADE WAS STABILIZED WITH BITUMINOUS MATERIAL AND CAPPED WITH THREE OR FINVE INCHES OF GRAVEL. TWO UNSTABILIZED CONTROL SECTIONS HAD A 7-INCH GRAVEL BASE. THE BEST PERFORMING STABILIZED SECTION WAS ONLY ON A PAR WITH THE CONTROL SECTIONS, BUT WAS MUCH MORE COSTLY. THE RELATIVE PERFORMANCE OF THE STABILIZED SECTIONS COULD BE REALTED TO RESULTS FROM LABORATORY TESTS CONDUCTED ON SIMILAR SOIL-BITUMINOUS MIXTURES. /FHWA/
