Frays Ridge Crossing— Sta 35+00 and Sta 40+00
JOB CODE: 2243
Dear Frank:
Enclosed are the results of two (2) CBR tests we ran on soil samples from the referenced site.
We have enclosed the moisture-density (compaction) curves, the sieve analysis results and
the stress-strain curves. Our personnel performed sampling in the field.
We hope this is the information you need. If you have any questions, please let us know.
Sincerely,
Gooch Engineering and Testing, Inc.

Dear Frank:
Shown in the enclosed table are the results of field density test numbers 1 through 50 our firm
ran on compacted fill at the referenced site. All tests either passed the required compaction of
95% maximum dry density according to ASTM D-698 or, where tests were low, the areas were
rerolled and retested until the requirements were met. The moisture was kept within specified
moisture parameters. The field density testing was performed with Troxler nuclear gauges
according to ASTM D-2922.
We trust this is the information you need. If you have any questions, please let us know.
