The relative compaction of a sand in the field is 92%. The maximum and minimum dry unit weights of the sand are 16.2kn/m^3 and 14.6Kn/m^3, respectively. For the field condition, determine a. Dry unit weight b. Relative density of compaction c. Moist unit weight at a moisture content of 12%
The relative compaction of a 4-m thick sand in the field is 79.34% and moisture content of 10.44%. The maximum and minimum dry unit weights of the sand are 108.66 lb/ft3 and 63.41 lb/ft3, respectively. If the specific gravity of the sand in the field is 2.644, determine the following: a. Bulk unit weight of the soil in the field, in lb/ft3. b. Relative density in the field, in %. c. Thickness of sand to satisfy a compaction requirement in the site to about 95%.
The maximum and minimum dry unit weights of a sand were determined in the laboratory to be 16.9 kN/m³ and 14.2 kN/m³, respectively. If the field relative density is 82%? Determine The degree of compaction in the field. Field dry unit weight. Field bulk unit weight if the field moisture content is 15%.
