The following data were obtained by conducting liquid limit and plastic limit tests on a soil collected from the site. Liquid limit tests: Plastic limit test: PL = 19.3% a. Draw the flow curve and determine the liquid limit. b. Using the Casagrande plasticity chart (Figure 4.21), determine the soil type.
Laboratory tests performed on a saturated alluvial subgrade soil gave the following information: In situ water content = 11.9%, Specific gravity = 2.65, Soil size distribution: D100 = 51 mm, D75 = 30 mm, D60 = 20 mm, D45 = 15 mm, D30 = 8 mm, D10 = 4.76 mm, D8 = 2 mm, D4 = 0.08 mm, < 2 m = 4% a. Is this soil well graded? Classify it by the AASHTO and Unified systems b. Using the sieve analysis soil data and the classification systems, estimate for a total of 100% the approximate percentages of coarse aggregate (gravel), fine aggregate (sand), silts, and clays?
Three kinds of experiments for measuring soil permeability coefficient
A moist soil sample having a volume of 1.16 m3 has a total mass of 2,314 kg. Specific gravity of soil is 2.66. If the water content is 8%, the degree of saturation in percentage. Please answer this asap. For upvote. Thank you in advance
A soil sample has the following size distribution; 4 to 2mm = 17%, 2 to 0.05 mm = 12%, 0.5 to 0.005 mm = 22% 0.005 to 0.002 mm = 10% <0.002 mm = 39% what are the percentages of clay, silt, and sand? Using USDA calssification what is the modifier and tetural classification
A soil sample has a unit weight of 1.9 g/cc and w=12%. If Gs of solids is 2.65, determine the volume of solids in cm3.
LL = 50% and PL = 23% If the soil had a natural water content of 56% prior to the Atterberg Limit test, explain the consistency condition of the soil at site.
The consistency limits of a soil sample are: LL=52%, PL=35%, SL=17%. If a specimen of this soil shrinks from a volume of 10 cc at liquid limit to 6.1 cc at plastic limit, determine the specific gravity of solids. Answer should be Gs=2.65.
Define the following properties of soil: • 1 Liquid Limit • 2 Plastic Limit 3 Plasticity Index
A soil sample has the following size distribution; 4 to 2mm = 17%, 2 to 0.05 mm = 12%, 0.5 to 0.005 mm = 22% 0.005 to 0.002 mm = 10% <0.002 mm = 39% what is the percent clay silt and sand? What are the modifier and textural classification?
