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.

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
