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