<RECENT VERSION>
1. Basics covered in Level 1 - ANSWER ✔ Nuclear Testing
Speedy Moisture
Report Forms
2. Earthwork has to do with the roadway in what way? - ANSWER ✔
Earthwork is the excavation and placement of soils and materials
supporting the proposed roadway.
3. In Earthwork what is a lift? - ANSWER ✔ 6" of compacted depth
at full width
4. In Earthwork what is a Lot? - ANSWER ✔ A lot is 1 lift at 500 ft
or within compacted area. Isolated compaction operations are
separate lots.
5. Sampling at the roadway is done for - ANSWER ✔ Done for base,
sub grade, and embankment.
6. Sampling is determined how - ANSWER ✔ generated with
random numbers usually by a Verification Inspector
7. What is important about sampling at the roadway - ANSWER ✔
Minimum of three representative sample combined.
,8. What is LIMS? - ANSWER ✔ Laboratory Info Management
System
9. The proctor theory is when compaction is achieved how -
ANSWER ✔ by inputting energy to expel air and water in the soil
voids
10. Compaction causes - ANSWER ✔ An increase in unit
weight, decrease in compressibility and permeability.
11. Determine the dry density by - ANSWER ✔ Taking the wet
density / 1.(moisture) = dry density
To the nearest 0.1pcf
12. To determine the percent maximum density - ANSWER ✔
Take the
calculated dry density / the maximum density from proctor x 100 =
% max density to the nearest whole percent
13. How often does the speedy and scale need to be calibrated -
ANSWER ✔ every 6 months
Scale verified daily by inspector
14. For a 20g and a 26g how much reagent do you use -
ANSWER ✔ 20g - 2 scoops
26g - 3 scoops
15. Minimum mixing time for Coarse and Clay material -
ANSWER ✔ Coarse - 1 minute
Clay - 3 minutes
16. On limerock you use the what reading - ANSWER ✔ Direct
Dial
, 17. If a dial reading exceeds 20% then you - ANSWER ✔ Re-run
with half the sample (10 or 13) and perform the test normally and
double the dial reading by 2
18. If a dial reads 0 or extremely low - ANSWER ✔ Re-run with
double the sample (40 or 52) and perform the test and divide the
dial reading by 2
19. If the speedy gets hot - ANSWER ✔ Let it cool in shade
20. If the speedy is cold - ANSWER ✔ >50F disregard and retest
21. Retest speedy if material comes out - ANSWER ✔ in lumps
after test
22. Reagent and the sample creates what gas - ANSWER ✔
Acetylene gas and a mild alkali, calcium hydroxide (lime)
23. All test data is recorded where - ANSWER ✔ Earthwork
density report
24. QC density compare log in data is for - ANSWER ✔ Initial
start up and standard counts
25. Use the water table sign on - ANSWER ✔ The graph plots
using an upside down triangle with a ling under it and have it dated
and signed
26. Earthwork is the construction work necessary to produce
roadbeds of the proper:
- grade
