Alternate Pavement Design
Coppell, Texas
BDD Project No. C96296
1-14-96 P03:40 IN
Dear Mr. Griffin:
We respectfully request that an alternate pavement section be allowed for the abe e referenced project.
In lieu of lime stabilization, the pavement strength will be increased from 3500 to 4000 psi at 28
days (6" in truck dock and drive lanes, 5" in passenger car parking area).
I have enclosed the soils report from Maxim Technologies for the project. Thei~ recommendation for
moderate heavy truck parking is 6" 3500 psi concrete with lim subgrade. Their
recommendation for automobile traffic is 5" 3000 psi concrete without lime-tre~ subgrade.
If you have any questions please feel free to call.
Sincerely,
Project Engineer
