The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.The test is named in honor of Ralph Roscoe Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil ...

More DetailsThis paper reports lab experiments measuring the effects on maximum dry density resulting from the mixing of sands with different grading characteristics. The maximum densities of the mixed sands were compared to the values apparently predicted by taking the average of the initial sands. The values are not the same, with the mixed sand ...

More Details· An increase in dry density will result as the grading moves towards more ideal characteristics for dense packing. Laboratory compaction tests using pluviation and the vibrating hammer method have been carried out to measure this increase in dry density. The resulting value is generally significantly greater than the result predicted by taking ...

More DetailsGrading curves are often included in ground investigation reports. Results of grading tests can be tabulated using geometric properties of the grading curve. These properties are called grading characteristics. First of all, three points are located on the grading curve: d 10 = the maximum size of the smallest 10% of the sample

More DetailsThe moisture content of the plus 0.75 inch (19 mm) rock material is generally negligible, so that a dry in-place rockfill density can be computed knowing the moisture content of the minus 0.75 inch (19 mm) material fraction.
