FDOT EARTHWORK LEVEL 1 EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS
The standard block and gauge must have matching - Answer-serial numbers
If daily standard counts are out of tolerance even after being re-run what do you do? -
Answer-Replace gauge
Gauge calibration must be performed by - Answer-qualified personnel
How often must the gauge be calibrated per FDOT - Answer-Annually (FDOT) or when
needed
Take standard counts daily to - Answer-detect inconsistencies early
Standard counts are taken - 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? -
Answer-Idle
During a standard count the gauge must be how far from large objects - Answer-10ft
During a standard count the gauge must be how far from any nuclear source - Answer-
30ft
The standard count must be performed on what time of ground - Answer-Aspahlt,
concrete, or >100pcf material (greater than)
Keep the standard block and gauge - Answer-level and stable
For turning on the gauge how must it be handled - Answer-Warm up per manufacturer's
instructions
How do you determine the day to day shift - 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 - Answer-a shift of 1% or less
The shift tolerance for moisture counts is - Answer-a shift of 2% or less
A gauge must be how far from all vertical projections - Answer-6 inches
When smoothing a test site remove all what? - Answer-Loose and disturbed material
The material identification number for embankment in the laboratory is - Answer-004L
The material identification number for embankment in the field is - Answer-004F
The material identification number for base is - Answer-030
PP is short for - Answer-project personel
Sampling in the field it is important to - Answer-sample each type of material and have
enough for a representative sample
When to secure samples - Answer-After material is placed but before compaction effort
is applied
Sample transmittal card the source uses what code for the jobsite - Answer-08
For material description the minimum is always - Answer-Color and texture
On sample bags be sure to put - Answer-Project #
Sample #
Location
What is the document that itemizes the minimum requirements for sampling and
testing? - Answer-Sampling, testing, reporting guide
Unit weight is - Answer-the weight of a material occupying a volume
Wet density - Answer-is the weight of soil and water in a volume
Dry density - Answer-weight of soil solids in a volume
Moisture content - Answer-amount of water in the soil in the volume
How does moisture react with soil - Answer-acts as a lubricant permitting maximum
densification
Compaction expels air and water causing - Answer-Increase in unit weight
and
