FDOT Earthwork Level 1 2022 Exam
Questions and Answers All Correct
What is the scaler on the gauge? - Answer-The digital readout
What do you obtain from a density reading? - Answer-Wet density
Soil Dry Density Count
Soil Moisture Count
Record the wet density at an accuracy of - Answer-the nearest 0.1 pcf
Record the dry density county at an accuracy of - Answer-the nearest 0.1 pcf
Record the percent moisture to (if approved) - Answer-the nearest 0.1%
When can percent moisture be approved to be used with a gauge? - Answer-When the
gauge and material has been approved
If a gauge is not approved you have to do what - Answer-Dig to depth of hole and obtain
a sample from the side walls for a speedy test
Determine the dry density by - Answer-Taking the wet density / 1.(moisture) = dry
density
To the nearest 0.1pcf
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
How often does the speedy and scale need to be calibrated - Answer-every 6 months
Scale verified daily by inspector
For a 20g and a 26g how much reagent do you use - Answer-20g - 2 scoops
26g - 3 scoops
Minimum mixing time for Coarse and Clay material - Answer-Coarse - 1 minute
Clay - 3 minutes
On limerock you use the what reading - Answer-Direct Dial
, 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
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
If the speedy gets hot - Answer-Let it cool in shade
If the speedy is cold - Answer->50F disregard and retest
Retest speedy if material comes out - Answer-in lumps after test
Reagent and the sample creates what gas - Answer-Acetylene gas and a mild alkali,
calcium hydroxide (lime)
All test data is recorded where - Answer-Earthwork density report
QC density compare log in data is for - Answer-Initial start up and standard counts
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
A failed test is plotted on a graph how - Answer-X with a circle around it
An Earthwork Density Report - Answer-is for density recordings
A summary of proctors sheet is for - Answer-different materials with lab proctors
(maximum density)
The lot index and special conditions is for - Answer-detailing verification pass or fails
All of the QC report forms - Answer-same as the QC's but for VT's
The dry density on log in data sheets is - Answer-the computed dry density calculated
with the speedy
Graph plot and counting lifts - Answer-x axis is lifts, one box is a lift
y axis is station numbers and the boxes go by 5
FM T-238 details - Answer-the designation number for the nuclear density test
Why is the Proctor test important - Answer-- it gives us the density that the contractor
must achieve
- provides the moisture range that allows for minimum compact ice effort to achieve
density.
- provides data on the behavior of the material in relation to various moisture contents.
