RE: Project No. 200-0361
Prestwick
Coppell, Texas
Dear Mr. Delsanter:
Per your request, a representative of GEE Consultants, Inc. obtained several samples of the pavement subgrade
material at the above referenced project. Samples were obtained from the existing exposed subgrade.
The samples were transported to the laboratory and classification test were performed. The test results are as
follows:
Sample # Location Description Liquid Plastic Plasticity
Limit Limit Index
1 Prestwick Court Brown and 33 15

Based on the above, a lime series test was performed on Sample No. 1 with the following results:
% Lime Added Liquid Plasticity
(by Dry Weight) Limit Index
0 33 18
3 31 4
5 32 5
7 32 4
Based on the above results and our experience, it is our recommendation that a minimum of six (6) percent lime
(by dry weight) be added.
This would be equivalent to approximately 30 pounds per square yard for a six (6) inch thick subgrade layer.
Pavement subgrade should be adequately compacted and moisture conditioned in accordance with accepted plans
and specifications. Our recommendations are based on the assumption that a minimum six (6) inch thick 3,000
psi Portland cement concrete pavement will be utilized.
If you have any questions or if you require further information, please do not hesitate to contact us.
Sincerely,
Richard W. Gee, P.E.
President
