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
The material identification number for base is - ANSWER 030
PP is short for - ANSWER project personel
Sampling in the field it is important to - ANSWER sample each type of material and
have enough for a representative sample
When to secure samples - ANSWER After material is placed but before compaction
effort is applied
Sample transmittal card the source uses what code for the jobsite - ANSWER 08
For material description the minimum is always - ANSWER Color and texture
On sample bags be sure to put - ANSWER Project #
Sample #
Location
What is the document that itemizes the minimum requirements for sampling and
testing? - ANSWER Sampling, testing, reporting guide
Unit weight is - ANSWER the weight of a material occupying a volume
Wet density - ANSWER is the weight of soil and water in a volume
Dry density - ANSWER weight of soil solids in a volume
Moisture content - ANSWER amount of water in the soil in the volume
How does moisture react with soil - ANSWER acts as a lubricant permitting
maximum densification
