FDOT Earthwork Level 1 Exam
Questions with Complete Solutions
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
Decrease in compressibility and permeability (ability of water to flow through)
MSE wall stands for - Answer-Mechanically stabilized earth wall
, FM 1 T-80 refers to which proctor - Answer-Modified
AASHTO T 99 refers to which proctor - Answer-Standard
Density is the measuring of - Answer-the dry density of soil compared to max dry
density determined by proctor % compaction
When is the density be more than 100% of the maximum dry density on the proctor
test? - Answer-If compactive effort is more applied in field than lab
Direct transmission is - Answer-a rod with Cesium-137 lowered to depth. The photons
pass through material to the gauge.
Backscatter geometry is - 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 - 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
