NETTCP Soils and Aggregate/ Concrete Inspector
NETTCP SOILS AND AGGREGATE / CONCRETE INSPECTOR COVERAGE
The Soils and Aggregate/Concrete Inspector certification administered by the
New England Transportation Technician Certification Program evaluates a
candidate's knowledge of fundamental construction materials used in
transportation and civil
engineering projects. The coverage includes soil classification, compaction
principles, moisture-density relationships, and field testing procedures for
soils and aggregates. It also assesses understanding of aggregate properties,
gradation,
sampling techniques, and quality control requirements. In addition, the exam
covers basic concrete technology, including mix components, curing methods,
slump
testing, strength development, and inspection of concrete placement.
Safety practices, documentation standards, and compliance with
construction
specifications are also emphasized
,D 3663 suggests that the stratified random sampling procedure is the best
and most practical method for ensuring that samples of construction
materials include the full range of a construction process.
True
Multiply the random number generated by the calculator by 100 and
round to the nearest whole number in order to determine the column of
the table that contains the desired random number.
False
Random numbers drawn are final, no matter what the situation they must
be used and not discarded or else the random method will be
jeopardized.
False
Thise procedure covers sampling aggregate for the purpose of preliminary
investigation.
False
Sampling is equally important as the testing, and the sampler shall
use every precaution to obtain samples that will show the nature
and conditions of the materials which they represent.
True
,One way of describing the maximum size is that it is the first sieve through
which all material is required to pass.
True
Sample size should be large enough so that after the sample is split twice
there will be a sufficient testing sample size.
True
Sampling devices that are used to interrupt flowing aggregate streams
must be capable of interrupting at least 3/4 of the flow of aggregate in
order to provide reasonable samples.
False
Under no circumstances should power equipment be used to sample
aggregates from stockpiles.
False
, AASHTO stipulates two stockpile sampling methods: sampling from a flat
surface created by a loader, and sampling from a horizontal surface on the
stockpile face.
True
When sampling from a stockpile without the assistance of power equipment,
the
sampler should divide the pile into quarters and obtain a sample from each
quarter.
False
The technique for shoveling from a stockpile stipulates that only material from
the outermost layer should be obtained in the sample.
False
According to AASHTO R 90 at least 100 lb of material with a nominal
maximum size of 1 in. should be sampled.
True
When multiple increments are obtained they should be of equal size and
thoroughly combined to form a single sample.
True
The size of aggregate samples required by AASHTO is determined by the
maximum size of the aggregate being tested.
False
