FDOT EARTHWORK LEVEL 1 Exam (3
Versions) Questions and Detailed Verified
Answers Graded A+ 100% Verified
When is the density be more than 100% of the maximum dry
density on the proctor test? - ✔✔✔ Correct Answer > If
compactive effort is more applied in field than lab
How often does the speedy and scale need to be calibrated -
✔✔✔ Correct Answer > every 6 months
Scale verified daily by inspector
For a 20g and a 26g how much reagent do you use - ✔✔✔
Correct Answer > 20g - 2 scoops
26g - 3 scoops
,Minimum mixing time for Coarse and Clay material - ✔✔✔
Correct Answer > Coarse - 1 minute
Clay - 3 minutes
Direct transmission is - ✔✔✔ Correct Answer > a rod
with Cesium-137 lowered to depth. The photons pass through
material to the gauge.
Backscatter geometry is - ✔✔✔ Correct Answer >
gamma photons reflected on to material and required to have
at least one reach the gauge.
The standard block and gauge must have matching - ✔✔✔
Correct Answer > serial numbers
If daily standard counts are out of tolerance even after being
re-run what do you do? - ✔✔✔ Correct Answer >
Replace gauge
Gauge calibration must be performed by - ✔✔✔ Correct
Answer > qualified personnel
,How often must the gauge be calibrated per FDOT - ✔✔✔
Correct Answer > Annually (FDOT) or when needed
Take standard counts daily to - ✔✔✔ Correct Answer >
detect inconsistencies early
Standard counts are taken - ✔✔✔ Correct Answer >
every day its used and to measure equipment aging and drift
In the gauge diary (for standard counts) when it is not used
what do you put down? - ✔✔✔ Correct Answer > Idle
During a standard count the gauge must be how far from large
objects - ✔✔✔ Correct Answer > 10ft
During a standard count the gauge must be how far from any
nuclear source - ✔✔✔ Correct Answer > 30ft
, The standard count must be performed on what time of ground
- ✔✔✔ Correct Answer > Aspahlt, concrete, or >100pcf
material (greater than)
Keep the standard block and gauge - ✔✔✔ Correct
Answer > level and stable
For turning on the gauge how must it be handled - ✔✔✔
Correct Answer > Warm up per manufacturer's
instructions
How do you determine the day to day shift - ✔✔✔ Correct
Answer > Find the Average of the previous 4 counts.
Find the difference between the avg and that days count.
Take the difference and divide it by the average.
Multiply the result by 100.
Do this for for both density and moisture counts separately.
The shift tolerance for density counts is - ✔✔✔ Correct
Answer > a shift of 1% or less
