NICET SOILS LEVEL 1 EXAM 2026 UPDATED
ACTUAL EXAM WITH CORRECT SOLUTIONS.
If used, how much wetting agent should be used in procedure
B? C117 - correct answer- Enough to produce a small amount
of suds when the sample was agitated
Define C117 - correct answer- The determination of the amount
of material finer than a 75-um (No.200) sieve
Report the amount retained by wash by....?(C117) - correct
answer- <10%-report to the .1%
What is the significance of C136? - correct answer- -To
determine the grading of materials, >10%-report to the nearest whole number
-compliance of particle size distribution,
-provide data for control of production of various aggregate
-developing relationships concerning porosity and packing How long do you sieve material? C136 - correct answer- so that
not more than 1% of material retained on any sieve will pass
during 1 minute of hand sieving
What procedure should always be used unless otherwise
specified in c117? - correct answer- Procedure A
How accurate shall balances be fo fine aggregate? C136 -
correct answer- readable to the nearest .1 Gram or .1%
What is an appropriate wetting agent to use for sieving through
a No.200 sieve? - correct answer- Water or any dispersing
agent that will promote separation of the fine materials How accurate shall balances be for course aggregate or
mixtures? C136 - correct answer- readable to the nearest .5
gram or nearest .1%
What should the temperature of the oven be when drying
samples?(C117) - correct answer- 110 °C (+-5)

What is the significance of C117? - correct answer- Accurate What shall be done if there are any discernable Variations in a
determination of material finer than 75-um in mineral aggregate stockpile? D75 - correct answer- Corrective action shall be
by washing taken to establish homogeneity in the material
What practice is used for sampling aggregate? - correct If it is necessary to indicate the degree of variation in a
answer- D75 stockpile, what shall be done? D75 - correct answer- Separate
samples shall be drawn from separate areas of the pile
The investigation of potential sample material should be
performed by....? D75 - correct answer- A responsible, trained What increases when sampling from the beginning or the final
and experienced person few tons of a conveyor belt? D75 - correct answer- The
potential of obtaining segregated material
What should a stockpile be visually inspected of? D75 - correct
answer- Discernable Variations When should method A be used in a standard proctor? D698 -
correct answer- When 25% or less material is retained on a No.
4 sieve
Where shall a sample be obtained where practicable?D75 -
correct answer- From the finished product
When should method B be used for standard proctor? D698 -
correct answer- When 25% or less material is retained on a
3/8" sieve
After a sample is obtained what shall not be done unless
required for testing purposes? D75 - correct answer- Further
crushing or manual reduction
