8. The looseness or denseness of sandy soils can be expressed numerically by the so-called relative density, D, and is defined by the following equations: emax -e Parymax Pary -Parymin Dr = етах - еmin 100% = 100% Pary \Parymax - Parymin, emax = void ratio of the sandy soil in its loosest state or at Parymax emin = void ratio of the sandy soil in its densest state or at Parymin e = void ratio of the soil for the situation of interest or at Pary With the aid of the above equations, compute for the dry unit weight, void ratio and relative density for a sample of mass 1830 g from the field having a volume Of 0.001 m3. The soil has a specific gravity of 2.60 and water content of 10%. Laboratory procedures establish a maximum void ratio of 0.62 and a minimum void ratio of 0.43.

Question
Transcribed Image Text:8. The looseness or denseness of sandy soils can be expressed numerically by the so-called relative density, Dr and is defined by
the following equations:
етах
Parymax
Pary – Parymin
- e
Dr
100%
100%
етах — етin
Pary
\Parymax – Parymin,
emax = void ratio of the sandy soil in its loosest state or at Pdrymax
emin = void ratio of the sandy soil in its densest state or at Parymin
e = void ratio of the soil for the situation of interest or at Pary
With the aid of the above equations, compute for the dry unit weight, void ratio and relative density for a sample of mass 1830 g
from the field having a volume Of 0.001 m³. The soil has a specific gravity of 2.60 and water content of 10%. Laboratory
procedures establish a maximum void ratio of 0.62 and a minimum void ratio of 0.43.
