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