A 50m *30m site has 1 m thick layer of organic soil, to be replaced with granular fill (Gs=2.6) with 21% fines and 31% oversized particles (Gos= 2.60 and wssD = 1.9%). The site is prepared for 10-story building with a parking lot. Standard Proctor tests are performed on the fill material without oversized particles, and the test results are shown below.

![A 50m*30m site has 1 m thick layer of organic soil, to be replaced with granular fill (Gs-2.6) with 21%
fines and 31% oversized particles (Gos= 2.60 and wsSD = 1.9%). The site is prepared for 10-story building
with a parking lot. Standard Proctor tests are performed on the fill material without oversized particles,
and the test results are shown below.

1) What are the key performance parameters?
2) Determine the parameters needed for field compaction.
3) If the average productivity of a single compactor is 30 m³/hr, how many days are need to finish the
compaction work, assuming 8 working hours per day?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c48a60d-f3c7-4fc8-ab5f-2a2038178462%2F1c5876ef-a07c-4307-b24d-f03cbe4ffa55%2F5705w8p_processed.jpeg&w=3840&q=75)
