Define C117 - Answer-The determination of the amount of
material finer than a 75-um (No.200) sieve
How accurate shall balances be fo fine aggregate? C136 -
Answer-readable to the nearest .1 Gram or .1%
How accurate shall balances be for course aggregate or
mixtures? C136 - Answer-readable to the nearest .5 gram
or nearest .1%
What is the significance of C117? - Answer-Accurate
determination of material finer than 75-um in mineral
aggregate by washing
What practice is used for sampling aggregate? - Answer-
D75
The investigation of potential sample material should be
performed by....? D75 - Answer-A responsible, trained and
experienced person
,2|Page
What should a stockpile be visually inspected of? D75 -
Answer-Discernable Variations
Where shall a sample be obtained where practicable?D75
- Answer-From the finished product
After a sample is obtained what shall not be done unless
required for testing purposes? D75 - Answer-Further
crushing or manual reduction
What shall be done if there are any discernable Variations
in a stockpile? D75 - Answer-Corrective action shall be
taken to establish homogeneity in the material
What is the significance of C136? - Answer--To determine
the grading of materials,
-compliance of particle size distribution,
-provide data for control of production of various
aggregate
-developing relationships concerning porosity and packing
,3|Page
What procedure should always be used unless otherwise
specified in c117? - Answer-Procedure A
What is an appropriate wetting agent to use for sieving
through a No.200 sieve? - Answer-Water or any dispersing
agent that will promote separation of the fine materials
What should the temperature of the oven be when drying
samples?(C117) - Answer-110 °C (+-5)
If used, how much wetting agent should be used in
procedure B? C117 - Answer-Enough to produce a small
amount of suds when the sample was agitated
Report the amount retained by wash by....?(C117) -
Answer-<10%-report to the .1%
>10%-report to the nearest whole number
How long do you sieve material? C136 - Answer-so that
not more than 1% of material retained on any sieve will
pass during 1 minute of hand sieving
, 4|Page
If it is necessary to indicate the degree of variation in a
stockpile, what shall be done? D75 - Answer-Separate
samples shall be drawn from separate areas of the pile
What increases when sampling from the beginning or the
final few tons of a conveyor belt? D75 - Answer-The
potential of obtaining segregated material
When should method A be used in a standard proctor?
D698 - Answer-When 25% or less material is retained on a
No. 4 sieve
When should method B be used for standard proctor?
D698 - Answer-When 25% or less material is retained on a
3/8" sieve
When should method C be used for standard proctor?
D698 - Answer-When 30% or less material is retained on a
3/4" sieve
When should a correction factor be established on a
standard proctor? D698 - Answer-When the test specimen
contains more than 5% of oversize fractions
