MOISTURE, DENSITY AND SLOPE REQUIREMENTS IN HIGH FILLS

Eight soils commonly used in highway construction in Missouri were selected for study based on diversity in geologic origin, areal distribution and range in physical characteristics. Physical indices, consolidation and shear strength characteristics were determined. Theoretical pore pressures possible in field conditions were calculated based upon procedures outlined by Hilf. Effective stress stability analyses were performed to relate molding moisutre at constant compactive effort to height of fill, angle of slope and factor of safety. In all cases, saturated strengths were assumed as a limiting condition. Potential settlements were related to molding moistures at constant compactive effort for various heights of fill. Limited investigation was made of the effects of variable compactive efforts. Results of the study are believed to be in reasonable agreement with limited data available from case studies. /FHWA/
