This can lead to bloody mucus in nose areas when the blood resulting from this minimal trauma is mixed in with regular clear mucus. And, when blood dries, mucus color can change again, becoming tinged with shades of brown or dark red when dislodged from the nasal area. Therefore brown mucus from nose areas is not uncommon during times of illness or other nose maladies.
Soil Compaction Tests. There are many types of Soil compaction tests which are performed on soil. One of the most common test to determine the field density of soil is the sand-cone method. Maximum density is found by plotting a densityâmoisture curve.
contents form a smooth curve, called the compaction curve, which is used to obtain the optimum. water content and maximum dry density. The two standardized tests in use today, the standard. and modified Proctor tests, differ only by the amount of compactive energy. In practice, the. standard or modified Proctor test is conducted on a soil and specifications are written stating: 1) that the soil moisture content during compaction should be within a specified percent of the. optimum water content; and 2) that the dry density of the compacted soil should be 90 to 100.
