Dear Mr. Griffin:
Per the August 13, 1998 request of Mr. Daniel Heischmen of Dowdey Anderson & Associates a
representative of GEE Consultants, Inc. obtained two (2) samples of the pavement subgrade material
at the above referenced project. The purpose of oar sampling was to perform testing to determine
the necessity for pavement subgrade lime stabilization. An auger or shovel was used to reach the
appropriate subgrade level.
An auger or shovel was used to reach the appropriate subgrade level. The samples were transported
to the laboratory and classification tests were performed. The test results are as follows:
Snmvle No. 1
Sample Location: Proposed Fir~ Lane North of Playground, 200' E. and
80' N. Of SW corner of Heartz Road and Vanbebber
Road.
Sample Depth: 1' to 1'-6"
Sample Description: Brown Sandy Clay
Liquid Limit: 32
Plastic Limit: 16
Plasticity Index: 16
Percent Passing No. 200 Sieve: *
· - Test Not Completed

Sample No. 2
Sample Location: Proposed Fire Lane E of Playground, 400' S and 20'
S of SW corner of Heartz Road and Vanbebber Road.
Sample Depth: 1' to 1'-6"
Sample Description: Brown Sandy Clay
Liquid Limit: 37
Plastic Limit: 25
Plasticity Index: 12
Percent Passing No. 200 Sieve: *
· - Test Not Completed
Based on the above listed test results, and our past experience, it is our opinion that pavement
subgrade soils tested do not necessarily_need to be lime stabilized. The soils tested arc similar to
those encountered at test borings advanced as part of our original geoteclmical investigation (Report
No. F-196-0244 dated October 11. 1996), This is based on the assumption that a mirfimum of five
(5) inches of portland cement concrete pavement will be utilized per Dowdey Anderson's paving and
grading plan dated May 26, 1998.
Exposed pavement subgrade should be scarified and compacted in accordanr, c with recommendations,
included in thc "Site Preparation" section of our original report dar~xi October 11, 1996.
If you have any questions or if you require further information, please do not hesitate to contact us.
Sincerely,
GEE Consultants, Inc.
