Clay:

 

I have attached the concrete mix designs provided by Lattimore Materials
Company.

There are two mix designs: one for the apron (5507) and one for the
parking lot area (5409).   

 

I have reviewed both mix design, and I am forwarding to you for approval
for this project.

 

I believe that Mix design 5507 for the apron area does meet the
requirements for paving as specified in FFA Circular 150/5370-10d Part
VI Rigid Pavements (Item P-501 Portland Cement Concrete Pavement).  Mix
5507 was the same mix design used for the apron area for the previous
hangar project to the south.

 

Do you need hard copies? If so, how many copies do you need?

 

Thanks
