Moisture content = 5.75% Limit liquid = 53.5 Plastic limit = 31.6 Granulometry Sieve % Pass No. 4 100 # 40 68 # 200 54.3 Do you select the best answer? a) Inorganic silt and sand, with low plasticity b) Inorganic clay with low plasticity c) Clay silt, traces of gravel, dark Brown
You are checking a field-compacted layer of soil. The laboratory control curve has the following values: gd (kN/m3) w (%) 16.34 14 16.57 16 16.65 18 16.50 20 16.26 22 15.87 24 The specification for compaction states that the field-compacted soil must be at least 95% of the maximum control density and within of the optimum moisture for the control curve. You dig a hole 1m3 in the compacted layer and extract a sample that weighs 17.2 kN wet and 14.1 kN dry. (a) What is the compacted gd? The compaction w? The percent compaction? Does the sample meet the specifications? (b) If the specific gravity is 2.68, what is the compacted degree of saturation? If the sample were saturated at constant density, what would be the water content?
Question 30 The data from a falling head test is shown. Diameter of standpipe: 6 cm. Initial Head: 90.4 cm. Duration of test: 18 min. Length of soil sample: 30.35 cm. Diameter of permeameter: 44 cm. If the soil permeability is 0.0038 cm/min, determine the final head (in cm.) of the permeability test. Round off to two decimal places.
The table shows the laboratory results of the sieve analysis of a sample. Plot the grain size curve of the soil. The soil has a liquid limit of 35% and plasticity index of 26%.
