The results of a sieve analysis on 911.3gr of a soil are shown in the table below: Sieve size (mm) 9.5 4.75 2.36 1.18 0.075 Mass retained (gr) 16 45 247 170 223 Liquid limit test using the Casagrande apparatus performed on the fine portion of the soil resulted in the following data: Number of blows, N 14 19 29 39 Test # Mass of moisture can (gr) 1 2 3 Mass of wet soil + can (gr) 70.5 94.1 72.3 48.4 Mass of dry soil + can (gr) 47.3 62.1 51.5 36.9 13.8 14.5 17.7 4 16.2 Repeated rolling of samples of the soil has shown that the plastic limit of the fine portion of the soil is PL = 40%. 1) How much is the liquid limit of the soil sample? (in %) (1 mark) Liquid limit= 1% 2) What is the classification of the soil according to USCS? (1.5 mark) (No answer given)
