What Is the significance of D1140? - ANSWER -The determination of the amount
of material finer than a 75-um sieve in soils by washing
What is the maximum particle size allowed in test method D1140? - ANSWER -
75MM (3 inch)
What is the dispersant allowed in D1140? - ANSWER -Sodium
Hexametaphosphate
What might a Soil Wash sample be obtained from? D1140 - ANSWER -Bulk
samples, jar samples, tube samples, or specimens used for other properties
How might a sample be reduced to testing size before a wash? D1140 - ANSWER
-quartering, use of a splitter, an entire jar sample, or cut a section from a tube and
quarter length wise
When performing a wash, what should the water temperature never exceed?
D1140 - ANSWER -32°C or 90°F to prevent the sieve fabric from expanding
What should happen if an insufficient amount of soil is is available for a wash?
D1140 - ANSWER -A smaller mass specimen may be used and report the reason
why
If a hose is used for a wash, what should be prevented? D1140 - ANSWER -
Splashing of material over the sides or water accumulation on the 75-UM screen
When is the sand cone method applicable? D1556 - ANSWER -For soils without
appreciable amounts of rock or course material in excess of 1.5" in diameter
What is the sand cone method used for? D1556 - ANSWER -Determine the in-
place density and unit weight of natural soil deposits, aggregate, soil mixtures or
similar material
, What are the requirements for the soil to make use of sand cones? D1556 -
ANSWER -It must have sufficient cohesion to maintain stable sides and be firm
enough to withstand minor pressures exerted in digging the hole without deforming
Sand cone method is not suitable for what? D1556 - ANSWER -Organic,
saturated, highly plastic soils, granular material or soils containing appreciable
amount of material larger than 1.5"
Describe the base plate of a sand cone. D1556 - ANSWER -may be round or
square,fall on the bottom, have sufficient thickness to be rigid and will be a
minimum of 3" larger than the funnel
What should the results be rounded to in the sand cone method?D1556 -
ANSWER -nearest decimal or significant digits
What should happen if a test location has small amounts of oversize fractions
during a sand cone test? D1556 - ANSWER -The test should be stopped and
moved to a different location
What should be used to fill the hole in the sand cone method? D1556 - ANSWER
-Free flowing sand of a known density and volume.
When are larger apparatuses needed during a sand cone test? D1556 - ANSWER -
When particles are larger than 1.5"
What is the specification for sand used in the sand cone method? D1556 -
ANSWER -uniformly graded, free of fines and fine sand particles and bulk density
variation should not be greater than 1%
What should be done to the sand before use in the sand cone? D1556 - ANSWER -
it shall be dried then allowed to reached an air dried state in the general location of
testing
What is specified to be acceptable sand for sand cone? D1556 - ANSWER -Bulk-
density variation between any one determination shall not be greater than 1%
What types of soils can be used in Modified proctors? D1557 - ANSWER -soils
that have 30% or less of their particles retained on the ¾" sieve and have not been
previous compacted
