P.O. No. 004208
Gentlemen:
Transmitted herewith are the results of two field density tests performed in the pavement base
rock layer for the subject project. We performed no tests in the pavement subgrade soils
prior to the placement of the base rock layer. The results of the field density and laboratory
compaction tests are contained in the attached Tables A and B, respectively.
If you have any questions, please call.
Very truly yours,
