The unit weight of a compacted sand backfill was determined by field measurement to be 1738 kg/m³. The water content and void ratio of the laboratory compacted soil was 10.2% and 60.7% respectively. What was the degree of compaction achieved in field? Assume water content remain constant (G = 2.7).
