SPECIAL TESTS FOR DESIGN OF HIGH EARTH EMBANKMENTS ON US-101

NEW HIGHWAY ROUTES THROUGH THE MOUNTAINS OF CALIFORNIA WILL NECESSITATE THE CONSTRUCTION OF SEVERAL EMBANKMENTS APPROACHING 400 FT IN HEIGHT. THE TESTING FOR USE IN DESIGN OF HIGH EMBANKMENTS INVOLVING SOIL-ROCK MIXTURES CANNOT BE ACCOMMODATED IN CONVENTIONAL TRIAXIAL EQUIPMENT. IN AN ATTEMPT TO SIMULATE EMBANKMENT STRESS CONDITIONS ON MATERIALS THAT WERE OF THE SAME TYPES AND SIZES AS CONTEMPLATED FOR THE PROTOTYPE, LARGE-SCALE TRIAXIAL TESTS WERE CONDUCTED ON 12-IN DIAMTER BY 28-IN HIGH SPECIMENS OF MINUS 3-IN MATERIAL AT CONFINING PRESSURES UP TO 125 PSI. HIGHER CONFINING PRESSURES TO 400 PSI WERE ALSO USED BUT THESE SPECIMENS WERE APPROXIMATELY 6 IN. IN DIAMETER BY 14 IN HIGH, AND THE MAXIMUM PARTICLE SIZE WAS 1 1/2 IN. TESTS WERE CONDUCTED TO OBTAIN BOTH TOTAL AND EFFECTIVE STRESSES. DEGRADATION OF THE MATERIALS UNDER COMPACTION, CONSOLIDATION, AND SHEARING WAS DETERMINED. THE TEST DATA ACQUIRED HAVE BEEN USED IN DESIGN OF ONE OF THE EMBANKMENTS WITH AN OVERALL HEIGHT OF 383 FT. /AUTHOR/
