FDOT Earthwork Level 1 2024-2025. Questions
and Correct Answers Graded A
A failed test is plotted on a graph how - ANSX with a circle around it
A gauge must be how far from all vertical projections - ANS6 inches
A job guide schedule is - ANSproject specific
A summary of proctors sheet is for - ANSdifferent materials with lab proctors
(maximum density)
AASHTO T 99 refers to which proctor - ANSStandard
After placing the gauge in the test hole be sure to do what with the gauge and rod
- ANSPull it gently to the side so the rod comes in contact with the hole
All of the QC report forms - ANSsame as the QC's but for VT's
All test data is recorded where - ANSEarthwork density report
Always drive the drill rod to testing depth length and - ANSanother 2 more inches
An Earthwork Density Report - ANSis for density recordings
, Backscatter geometry is - ANSgamma photons reflected on to material and
required to have at least one reach the gauge.
Basics covered in Level 1 - ANSNuclear Testing
Speedy Moisture
Report Forms
Compaction causes - ANSAn increase in unit weight, decrease in compressibility
and permeability.
Compaction expels air and water causing - ANSIncrease in unit weight
and
Decrease in compressibility and permeability (ability of water to flow through)
Comparison between VT and QC density test tolerance - ANS2 lbs/pcf
Density is the measuring of - ANSthe dry density of soil compared to max dry
density determined by proctor % compaction
Determine the dry density by - ANSTaking the wet density / 1.(moisture) = dry
density
To the nearest 0.1pcf
Direct transmission is - ANSa rod with Cesium-137 lowered to depth. The photons
pass through material to the gauge.
