✅ NICET Construction Materials Testing – Soils Level II
📘 FULL EXAM COVERAGE (DETAILED)
The NICET Soils Level II exam evaluates both theoretical
understanding and practical field/lab competency, focusing
on independent testing, troubleshooting, and interpretation.
1.
A technician performs a sieve analysis but forgets to wash
fines before testing. What is the most likely effect on soil
classification?
A. Overestimation of coarse fraction
B. Underestimation of fines content
,C. No effect on classification
D. Increase in liquid limit
✅ Answer: A
Rationale: Without washing fines, fine particles remain
attached to coarse grains, falsely increasing coarse
fraction.
2.
During a Standard Penetration Test, the hammer energy
is inconsistent due to equipment wear. What is the
primary concern?
A. Incorrect moisture content
B. Invalid N-values
C. Soil contamination
D. Improper classification
✅ Answer: B
Rationale: SPT results depend on consistent hammer
energy; variation invalidates blow count reliability.
3.
A soil sample shows LL = 45 and PL = 25. What is the
Plasticity Index?
,A. 20
B. 70
C. 25
D. 45
✅ Answer: A
Rationale: PI = LL − PL = 45 − 25 = 20.
4.
A nuclear density gauge shows erratic readings across
repeated tests at the same location. What is the most
probable cause?
A. Excessive compaction
B. Improper gauge seating
C. High plasticity soil
D. Correct calibration
✅ Answer: B
Rationale: Poor contact with soil surface leads to
inconsistent readings.
5.
During compaction, soil is placed significantly wet of
optimum moisture. What is the expected result?
, A. Increased dry density
B. Reduced strength and density
C. No change
D. Increased permeability
✅ Answer: B
Rationale: Wet soils reduce compaction efficiency, leading
to lower density and strength.
6.
A hydrometer analysis is performed without temperature
correction. What error occurs?
A. Incorrect particle size distribution
B. Increased compaction
C. Lower plasticity index
D. Incorrect sieve size
✅ Answer: A
Rationale: Hydrometer readings depend on temperature;
ignoring it skews particle size results.
7.
A technician records field density higher than maximum
lab density. What is the most likely explanation?
