- The Modified Proctor Compaction Curve For The Soil Sample From A Construction Site Is Shown In Fig 4 11 Along With The 1 (47.6 KiB) Viewed 24 times
The modified Proctor compaction curve for the soil sample from a construction site is shown in Fig. 4.11, along with the zero air void curve. The specific gravity of the soil grains is 2.70. The compaction specifications require that the soil at the site to be compacted to at least 95% relative compaction, with the moisture content to be in the range of +1% to +3% from the optimum moisture content. A field-density test was carried out where a hole is dug in the compacted ground and the volume was determined to be 1250 cm", and the soil removed from the hole has a mass of 2642 g. The entire soil from the hole is placed in the ground and the dry mass was 2287 g. Does the compaction meet the specifications?
