4. A field density test is performed by the rubber balloon method. The ff data was
obtained:
= 15.9 N
Weight of soil removed + pan
Mass of pan
Balloon Reading:
Final
= 1.25 N
= 1288 cm
= 538 cm3
Initial
Water Content information:
= 4.059 N
Weight of wet soil + pan
Weight of dry soil + pan
Weight of pan
Compute the dry unit weight and water content in the field. If the MDD is 18.6 kN/m, what is
the relative compaction?
= 3.65 N
= 1.22 N
