DEVELOP MORE SIGNIFICANT AND RAPID TEST PROCEDURES FOR QUALITY ASSURANCE TESTS RELATING TO SOIL MATERIALS

THE RESEARCH EFFORT TO IMPROVE AND STREAMLINE SOIL TESTING PROCEDURES WILL BE DIRECTED TOWARD BOTH IN SITU TESTING AND PREPARATION AND TESTING OF SPECIMENS IN THE LABORATORY. THIS WILL INCLUDE DEVELOPMENT OF RAPID TESTS OF SOIL PROPERTIES, PULVERIZATION OR DISAGGREGATION OF CLAY LUMPS PRIOR TO SELECTION OF SUB-SAMPLES, PROCESSING SAMPLES OF SHALE AND OTHER SOFT OR WEAKLY CEMENTED AGGREGATES, AND UNIFORM AND THOROUGH MIXING OF WATER INTO THE SOIL SAMPLE DURING PREPARATION FOR TESTING. FIVE STUDIES ARE SUGGESTED: (1) DETERMINATION OF THE MOISTURE-DENSITY RELATIONS OF GRANULAR MATERIALS; (2) DEVELOPMENT OF AN ULTRASONIC APPARATUS FOR THE REMOVAL OF CLAY OR OTHER FINE MATERIAL FROM COARSE AGGREGATE PARTICLES; (3) EVALUATION OF CURRENTLY AVAILABLE ELECTRONIC EQUIPMENT FOR RAPID SOIL PARTICLE SIZE ANALYSIS; (4) CORRELATION OF PENETRATION RESISTANCE WITH OTHER SOIL PARAMETERS SUCH AS SHEAR STRENGTH AND COMPRESSIBILITY; (5) ASSESSMENT OF THE CONTROLLED GRADIENT CONSOLIDOMETER TEST.
