THE FROST STABILITY OF GRAVEL AND SANDY MATERIALS STABILIZED WITH CEMENT

FIELD AND LABORATORY RESEARCH BY THE LENINGRAD BRANCH OF SOYUZDORNI IS DESCRIBED. CEMENT-STABILIZED SAMPLES WERE TESTED IN RUBBER BAGS WHICH MAINTAINED AN OPTIMUM MOISTURE CONTENT OF 6 TO 7%. AFTER FREEZING TO -20 DEGREES C, SAMPLES WERE THAWED IN AIR FOR 14 HOURS. CURVES ARE GIVEN OF WEIGHT LOSS AND COMPRESSIVE STRENGTHS, AND MODULI OF DEFORMATION ARE NOTED FOR A GIVEN NUMBER OF FREEZING CYCLES, PORE-WATER VOLUME, DENSITY OF MATERIAL AND CEMENT CONTENT. STABILIZATION OF SAND GRAVEL MATERIALS WITH 4 TO 8% CEMENT IS RECOMMENDED FOR ROAD BASES IN AREAS SUBJECT TO SEVERE FROST.
