Transcribed Image Text: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
Pdrymax
Pdry - Pdrymin
D,=
100% =
-) 100%

emar = void ratio of the sandy soil in its loosest state or at parymax
Lmin = void ratio of the sandy soil in its densest state or at pdrymin
e = void ratio of the soil for the situation of interest or at pdry
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.
