The suitability of these soil for densification using vibroflotation method. What are these soil?

Question 1 (1 point) Listen The sieve number denotes the number of holes present in the sieve within one inch length of the sieve mesh True False Question 2 (1 point) V Saved Listen What is the correction factor for a soil with Gs-2.70? 0.99 1.03 02.70

Based on the soil classification test, particle passing on sieve No. 200 is 89%, Liquid Limit is 38% and Plasticity Index is 20%. Classify the soil based on AASHTO (e.g: A-7-5 or A-2). GI is not required. Show steps to classify the soil in your attachment.

Textbook Problem Refer to the soil in Problem 4.1. a. Determine the flow index. b. Determine the liquidity index of the soil if the in situ moisture content is 21%. 4.1 During Atterberg limit tests in the soil mechanics laboratory, the students obtained the following results from a clayey soil. Liquid limit tests: Number of Moisture blows, N content (%) 14 38.4 16 36.5 20 33.1 28 270 Plastic limit tests: Students conducted two trials and found that PL = 17.2% for the first trial and PL = 17.8% for the second trial. a. Draw the flow curve and obtain the liquid limit. b. What is the plasticity index of the soil? Use an average value of PL from the two plastic limit trails.
