Earthwork has to do with the roadway in what way? - COrrECT aNSwEr-Earthwork is the
excavation and placement of soils and materials supporting the proposed roadway.
In Earthwork what is a lift? - COrrECT aNSwEr-6" of compacted depth at full width
In Earthwork what is a Lot? - COrrECT aNSwEr-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 - COrrECT aNSwEr-Done for base, sub grade, and
embankment.
Sampling is determined how - COrrECT aNSwEr-generated with random numbers
usually by a Verification Inspector
What is important about sampling at the roadway - COrrECT aNSwEr-Minimum of three
representative sample combined.
What is LIMS? - COrrECT aNSwEr-Laboratory Info Management System
The proctor theory is when compaction is achieved how - COrrECT aNSwEr-by inputting
energy to expel air and water in the soil voids
, Compaction causes - COrrECT aNSwEr-An increase in unit weight, decrease in
compressibility and permeability.
The proctor is determined where and creates what - COrrECT aNSwEr-In a laboratory
and establishes a density standard to be used on the roadway
Lab proctors are created how - COrrECT aNSwEr-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 - COrrECT aNSwEr-It is used in base, sub grade, MSE
wall back fill materials
Modified proctors are created how - COrrECT aNSwEr-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 - COrrECT aNSwEr-It is used in embankment and
structure back fill materials
Standard proctors are created how - COrrECT aNSwEr-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 - COrrECT aNSwEr-2 lbs/pcf
What is the STRG - COrrECT aNSwEr-Sampling, Testing, and Reporting Guide (state
wide)
A job guide schedule is - COrrECT aNSwEr-project specific
The material identification number for embankment in the laboratory is - COrrECT
aNSwEr-004L
