Question
1- A soil has a bulk density of 1.91 Mg/m and water content of 9.5%.
the value of Gs is 2.7, calculate the void ratio and degree of
saturation of the soil. What would be the values of density and water
content if the soil were fully saturated at the same void ratio?
2- Calculate Ya, Ysat, and Y of the soil having e=0.7 and Gs-2.72,
calculate also Y, w at Sr = 0.75.
3- The following results obtained from a saturated compaction test, Gs
=2.67. Plot the dry density -water content curve and give optimum
water content wopt and (pa )max . plote the curves of zero, 5% and 10%
air content and give the value of A at maximum density, the volume
of the mold is 1000cm3
