COMPACTION OF EMBANKMENTS, SUBGRADE TREATMENTS AND SOIL STABILIZATION

A LARGE NUMBER OF STATE HIGHWAY DEPARTMENTS HAVE ADOPTED, WITHOUT VARIATION, THE STANDARD METHOD SET UP BY AASHO TO OBTAIN THE MOISTURE DENSITY RELATIONSHIP FOR SOILS. KANSAS AND CALIFORNIA HAVE DEPARTURES FROM THIS PROCEDURE. THE PURPOSE OF THE TESTS FOR FINDING THE OPTIMUM MOISTURE CONTENT AND MAXIMUM DENSITY IS TO DETERMINE THE CHARACTERISTICS OF THE SOIL WHICH WILL BE PRODUCTIVE OF THE LEAST SETTLEMENT OR VOLUME CHANGE IN THE EMBANKMENT AFTER IT IS IN PLACE. SOME OF THE SUBGRADE TREATMENTS DISCUSSED WERE: ADDITION OF WATER, ROLLING, COMPACTION METHODS, COMPACTION TEST RESULTS, SOIL STABILIZED AGGREGATE MOISTURES WITH AND WITHOUT CHEMICAL ADMIXTURES, SOIL-BITUMINOUS, MIXTURES, AND SOIL-CEMENT MIXTURES. IT WAS CONCLUDED THAT TEST PROCEDURES FOR DETERMINATION OF BITUMEN AND MOISTURE CONTENTS SHOULD BE CHECKED AGAINST FIELD CONDITIONS AND THAT AN EFFORT BE MADE TOWARD STANDARDIZATION AND SIMPLIFICATION.
