Re: Paving Design

Dear Ms. Strolle:
Fly ash may be used in the pavement mix for the referenced project. It is recommended
the percent of fly ash be limited to 20 percent or less of the required cement. A mix
design proven to meet the required strength should be obtained from the concrete
supplier.
If any questions arise, do not hesitate to call.
Sincerely,
REED ENG NEERING ' S • .
