1. Half life: The rate of decay is measured by its
2. 1: The pH number that indicates the greatest acidity is
3. 5KG: Approximate mass of 49N weight is
4. Atomic nucleus: The atomic number is the number of protons in an atom
5. Flourine has an atomic weight of 19 and an atomic number of 9. What is the
number of neutrons in the atomic nucleus?: 10
6. An atom has 30 protons and 35 neutrons in its nucleus. It has 30 electrons
in its shells. Its atomic weight would be?: 65
7. Backfill for use around culverts and pipes consists of: Granular materials
8. An inspector looks through one end of a drainage pipe. He is most likely
checking: Alignment of the pipe
9. 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?: Larger trench widths mean more backfill material,
which increases costs.
10. The main purpose of sampling any material is?: Obtain a small part of a lot
to represent the whole.
11. What is the water cement ratio?: Weight of water/weight of cement
12. Wet sieve: Used to separate fine grain from coarse grain. It carried out by
washing the soil specimen on a 60pm sieve mesh.
13. 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?: Density check
14. Slump test of concrete test all but which one of the following? Water
cement ratio, admixture content, strength, durability/workability, water con-
tent.: Strength
15. For a concrete slump test how is the cone to be filled with concrete?: 3
equal layers according to volume
16. How is the bearing of a line notated?: S 23° 30' E
17. Horizontal distances over sloping ground are usually determined by?: Sur-
veying tape and plumbing bob
18. 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'?: Less
19. 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?: 45530-45020 = 510'
510 x 0.020 = 10.2'
1252.0 + 10.2 = 1262.2
Answer is 1262.2

20. What is the varnier on a leveling rod used for?: Used to determine the
subdivision of the smallest division of a scale.
21. What is the proper tension for a 100' steel tape?: 25 pounds
22. When measuring with a steel tape a sag is detected. What will the reading
be?: Too large
23. A number 6 reinforcing bar has what size diameter?: Multiply the size by 1/8"
6 x 1/8 = 0.75"
Answer is 0.75"
24. What does critical path method mean?: It is the speed a project can be
completed. It does not include any float days.
25. A map has a scale of 1" = 2.5 miles. The distance between two points is on
the map is 3". What is the actual distance on the ground between these two
points?: 3 x 2.5 x 5.280' = 39,600 ft.
26. Define a contour line: A line drawn on a plan, which connects all points of equal
elevation, above or below a known or assumed reference point or plane.
27. Drainage always occurs?: Perpendicular (at right angle) to the contour lines
28. What instrument is commonly used to check the area on a map?: Planime-
ter
29. In topographical maps, the lines drawn to show relief by means of hill
shading are called?: Hachures
30. A freeway rises 25 feet in 2 miles. What is the % grade?: Slope = rise/run
=25/(2 x 5280)
=0.00236
=0.00236 x 100 = 0.24%
31. What is the volume of a cone in cubic feet? Dimensions are 6" diameter,
and 10" height?: Come volume = À r^2h/3
=À(.5/2)^2(0.83)/3
=0.054 cf.
32. What is the volume of 6' diameter sphere in cubic feet?: Sphere volume =
4Àr^3/3
=4À3^3/3
=113 cf.
33. Solve the following equation if A=6, B=3, C=21:
X=A^2+B^2+C^2: X=(6^2)+(3^2)+(21^2)
X=22
34. What is the proper order of arithmetic operations?: PEMDAS
35. (x+4)(x+9)=?: Use FOIL method, first outer, inner last;
x^2+9x+4x+36
x^2+13x+36
