G. Mix Production
At the start of HMA mix production or when adjustments are made to the mix, the QC
Officer will coordinate the proportions with plant operator and, periodically throughout the
day, checks will be made on the mix per the sampling frequency set forth in the current
Division of Aeronautics Policy Memo 96-2. The results shall be recorded on the
appropriate forms and faxed to the Division of Aeronautics and the Resident Engineer
immediately upon completion.
H. Laydown
The mix will be laid on the prepared base in accordance with the specifications using the
following equipment:
(Paver and roller equipment made and model)
Should any adverse mix characteristics be observed, the laydown superintendent will
notify the QC Officer to review the manufacture of the mix and make adjustments if
necessary to correct the situation. No changes to the mix shall be made without
concurrence by the Division of Aeronautics.
I. Utilization of Personnel
Listed below are the duties to be performed by the various technical personnel assigned
to the project.
