2025 QUESTIONS AND ANSWERS
Basics covered in Level 1 - ANS Nuclear Testing
Speedy Moisture
Report Forms
Earthwork has to do with the roadway in what way? - ANS Earthwork is the excavation and
placement of soils and materials supporting the proposed roadway.
In Earthwork what is a lift? - ANS 6" of compacted depth at full width
In Earthwork what is a Lot? - ANS A lot is 1 lift at 500 ft or within compacted area. Isolated
compaction operations are separate lots.
Sampling at the roadway is done for - ANS Done for base, sub grade, and embankment.
Sampling is determined how - ANS generated with random numbers usually by a Verification
Inspector
What is important about sampling at the roadway - ANS Minimum of three representative
sample combined.

, What is LIMS? - ANS Laboratory Info Management System
The proctor theory is when compaction is achieved how - ANS by inputting energy to expel
air and water in the soil voids
Compaction causes - ANS An increase in unit weight, decrease in compressibility and
permeability.
The proctor is determined where and creates what - ANS In a laboratory and establishes a
density standard to be used on the roadway
Lab proctors are created how - ANS Material is gathered from the road and prepared with
different amounts of water then placed in molds and hammered
What is a modified proctor used in - ANS It is used in base, sub grade, MSE wall back fill
materials
Modified proctors are created how - ANS With a 10lb hammer(rammer) on a 18" drop with
56 blows per layers with 5 layers in total.
What is a standard proctor used in - ANS It is used in embankment and structure back fill
materials
Standard proctors are created how - ANS With a 5.5lb hammer(rammer) on a 12" drop with
25 blows per layer with 3 layers in total
Comparison between VT and QC density test tolerance - ANS 2 lbs/pcf
What is the STRG - ANS Sampling, Testing, and Reporting Guide (state wide)
