NICET LEVEL 1 IN HIGHWAY CONSTRUCTION FINAL EXAM PACK | QUESTIONS
AND DETAILED ANSWERS| 100% CORRECT| GRADE A+ |100% PASS
The title or key sheet is - ANSWER The first sheet in a set of project plans
It is an introductory sheet to the project that identifies the: - ANSWER Project name and
number, location of the project, index to all sheets in the plan set, length of the project,
specifications under which the project is to be built, states whether traffic is to be maintained or
detoured, lists standard construction drawings and supplemental specifications, contains the
signature of approval by the proper officials.
Plan and profile sheets show - ANSWER Construction of the highway from two views
The top half of the sheet shows - ANSWER Plan view and the bottom half shows a profile view
Sometimes, an entire sheet may be required just to show - ANSWER the plan view, and a
separate sheet may be required for the associated profile views
Typical section sheets show the - ANSWER Different layers of the road and the side slopes and
ditches for a particular given length. This view is as if the road was cut full depth perpendicular
to center-line. If the project was small and very simple it may have only one typical section.
However, most roads, have several typical sections. Typical sections are viewed looking
upstation.
Typical section sheets show - ANSWER Cross-section views at specified points along the
proposed roadway. They will show the existing ground line and will super-impose the proposed
roadway over the existing. Typical sections provide a cross-section view/picture of what the
roadway will look like.
Summary of quantities sheets - ANSWER This sheet will show in a table the quantities of all the
construction pay items anticipated for the complete construction of the roadway. These
,quantities are based on the final design estimate by the designer. These quantities will be used
in creating the schedule of the materials sampling plan.
Plan details - ANSWER A detail is a view of a very specific item of work. It can be a plan view,
but most likely will be a cross-section view. N.T.S. means not to scale.
Half life - ANSWER The rate of decay is measured by its
1 - ANSWER The pH number that indicates the greatest acidity is
5KG - ANSWER Approximate mass of 49N weight is
Atomic nucleus - ANSWER The atomic number is the number of protons in an atom
Flourine has an atomic weight of 19 and an atomic number of 9. What is the number of
neutrons in the atomic nucleus? - ANSWER 10
An atom has 30 protons and 35 neutrons in its nucleus. It has 30 electrons in its shells. Its
atomic weight would be? - ANSWER 65
Backfill for use around culverts and pipes consists of - ANSWER Granular materials
An inspector looks through one end of a drainage pipe. He is most likely checking - ANSWER
Alignment of the pipe
An important consideration in excavation for drainage is the trench width. Why is it important
to keep the trench width to that which is called for by the specifications, and not larger? -
ANSWER Larger trench widths mean more backfill material, which increases costs.
, The main purpose of sampling any material is? - ANSWER Obtain a small part of a lot to
represent the whole.
What is the water cement ratio? - ANSWER Weight of water/weight of cement
Wet sieve - ANSWER Used to separate fine grain from coarse grain. It carried out by washing
the soil specimen on a 60pm sieve mesh.
In soil testing the test used to determine the ratio of the weight of a given volume of material
to the weight of an equal volume of water is known as? - ANSWER Density check
Slump test of concrete test all but which one of the following? Water cement ratio, admixture
content, strength, durability/workability, water content. - ANSWER Strength
For a concrete slump test how is the cone to be filled with concrete? - ANSWER 3 equal layers
according to volume
How is the bearing of a line notated? - ANSWER S 23° 30' E
Horizontal distances over sloping ground are usually determined by? - ANSWER Surveying tape
and plumbing bob
A distance between two points 300' apart is measured on a hot day. The tape will show a length
greater than or less than 300'? - ANSWER Less
A road has a grade of 2.0% with an elevation of 1252.00 at station 450+20. What is the
elevation at station 455+30? - ANSWER 45530-45020 = 510'
510 x 0.020 = 10.2'
1252.0 + 10.2 = 1262.2
Answer is 1262.2
