A soil proposed for a compacted fill contains 38% fines and 62% coarse material by dry weight.
Question:
A soil proposed for a compacted fill contains 38% fines and 62% coarse material by dry weight. When the coarse fraction has w = 2.0%, its affinity for water is completely satisfied (that is, it is saturated but surface dry). The Atterberg limits of the fines are LL=31 and PL = 13. The soil is compacted by rolling to a ρd = 1.96 Mg/m3 at w = 15%.
(a) What is the water content of the fines in the compacted mass?
(b) What is the likely classification of the soil? (USCS and AASHTO)
(c) What is the liquidity index of the fines?
