Question

If a soil sample contains 80% sand and gravel and 20 % sit and clay. Its liquid limit equal 36 then, it could be classified as (d) None of the above (c) Fine soil (b) Sandy soil (a) Gravelly soil A sieve analysis was conducted on a soil specimen the out put results was as follows material retained on #4 = 25 % and on # 200 = 80 %. The soil could be classified as (c) Coarse grained soil (d) a & c (b) Gravelly soil (a) Sandy soil Coefficients of curvature and uniformity are considered in soil classification when fines percent equal to (d) a & c (c) 5-12% only (b)> 12% (a) <5% only D10 means that (b) The particle size equal 10 mm (a) The amount of fines equal 10% (c) Particle diameter corresponding to 10 % finer (d) 10 % of the particle diameter The criteria for describing coarse-grained soils are () Color, Moisture & Odor (IM) plasticity (I) Dilatancy, odor & consistency (li) Shape, angularity & structure (d) i & IV (b) II (c) l & II (a) Fine sand is defined as the material passing sieve (d) a & b (c) 0.002 mm (b) No. 40 (a) No. 200 Silt and clay size included in materials passing sieve (d) 75 mm (c) 0.075 mm (b) 0.002 mm (a) 2.00 mm .Standard drying temperature to determine moisture content of sail and rock in accordance to ASTM is (d) 11015 C (c) 105+5 C (a) 10015 °C (b) 85 ±5 °C
