Q1: A compacted fill currently under construction will support a proposed supermarket. One of the field density tests in this fill gave a unit weight of 121 pfc and a moisture content of 12.5%. A series of modified proctor tests have also been performed on the fill soils per ASTM D1557 and they gave a maximum dray unit weight of 130 Pcf and an optimum moistures content of 13%. Compute the relative compaction based on the modified proctor test.

7. How many classifications are there for sand based on the grain size distribution? a) 3 b) 2 c) 5 d) 4
In the construction of a road, the compaction specification required was 95% of Proctor maximum dry density at field moisture content within 2% of the optimum moisture content. The maximum dry density and optimum moisture content obtained in the laboratory from the Standard Proctor test were 1.94 gm/cc and 13.5% respectively. A site engineer conducted sand cone test at two locations and obtained the following results. Location No. 1 2 Mass of soil removed (gm) Wet 43.86 37.38 Dry 38.46 32.21 Mass of sand used (gm) 39.51 32.39 The density of sand used was 1.87 gm/cc. Check whether the specification was satisfied or not.

The degree of compaction of sand in the field is 93.5%. Considering a dry specific weight maximum “γd max” and minimum “γd min” (see Table 1) of this sand determine the dry specific weight in field and its relative compression compactness.
