LIME OR CHLORIDE TREATMENT OF GRANULAR BASE COURSE MATERIALS

RESULTS ARE PRESENTED OF TRIAXIAL TESTING OF THREE CRUSHED LIMESTONES TO WHICH EITHER HYDRATED HIGH-CALCIUM LIME, SODIUM CHLORIDE OR CALCIUM CHLORIDE HAD BEEN ADDED. LIME WAS ADDED AT RATES OF 1, 3, 10 AND 16 PERCENT, CHLORIDES WERE ADDED AT 0.5 PERCENT RATE ONLY. SPECIMENS WERE COMPACTED USING VIBRATORY COMPACTION APPARATUS AND WERE TESTED IN TRIAXIAL COMPRESSION USING LATERAL PRESSURES FROM 10 TO 100 PSI. TRIAXIAL TEST RESULTS INDICATE THAT: (1) SODIUM CHLORIDE SLIGHTLY DECREASED THE ANGLE OF INTERNAL FRICTION AND INCREASED COHESION, (2) CALCIUM CHLORIDE SLIGHTLY INCREASED THE ANGLE OF INTERNAL FRICTION AND DECREASED COHESION, AND (3) LIME HAD NO APPRECIABLE EFFECT ON ANGLE OF INTERNAL FRICTION BUT INCREASED COHESION, DECREASED DENSITY AND INCREASED PORE WATER PRESSURE. /BPR/
