A soil proposed for a compacted fill contains 40% fines and OU% eons* material by thy weight When the coarse fraction has w 1.5%, its affinity for water is completely satisfied (that is, it is saturated but surface dry). The Auctbets limits of the fines are LL - 27 and PL w 12. The soil is compacted by rolling to a p,m 2.0 Mg/m3 at w - 13% Note: This is the water content of the entire soil
(a) What is the water content of the fines in the compacted mass?
(b) What is the likely classification of the soil? (Give both the Unified and the AASHTO classifications)
(c) What is the liquidity index of the fines?
(d) What can you say about the susceptibility of the fill to (I) shrinkage-swelling potential? (2) potential for frost action?
(e) Is there certain type of compaction equipment you would especially recommend for this job? Why?
