You have arrived looking for DD Form 1218. Before you download, confirm this is the right document: Marshall Method - Computation of Properties of Asphalt Mixtures. Full title: DD Form 1218, Marshall Method - Computation of Properties of Asphalt Mixtures, December 1965.
Then look at the edition date: not stated, publisher status not stated. After that, ask whether the form covers your situation. It almost certainly does regardless of your branch — DD forms run Department-wide rather than through a single service.
Once you know the form fits, find out when you file it. not stated sets the requirement, and not stated maintains the form itself. Your own command or agency adds local timing on top of that, so ask your administrative office if the deadline matters to you.
Finally, decide how you will complete it. You can type into a fillable file or print a blank and write by hand, and the rest of this page walks you through both paths in order.
Start at the header. Complete your identification before anything else, then work through the main entries, then finish at the certification. Skipping around causes contradictions between the top of the form and the bottom.
Your first action is verification. Find the edition date on the form and match it against not stated. A mismatch means you are working from a superseded printing, and because DD forms change Department-wide rather than service by service, the office receiving it will notice.
Look up an unclear item on the form face before anywhere else, then in not stated. Should the two texts conflict, the directive is the one you follow.

With the form finished, route it to the office named in not stated or in your organization's own instruction. Keep a copy first. People rarely regret having one and frequently regret not having one.
Should you need a related form, look it up by its number. The DD sequence is Department-wide, which makes your search simple: no service qualifier, no branch-specific variant to track down.
Here is where people go wrong. They see a number in an instruction and download whichever form matches it. But DA and DD are separate systems — Army-specific in one case, Department-wide under not stated in the other — so check which series you were sent to before you take the file.
Come back and check the edition next time you need this form. Editions change when the prescribing directive is reissued, when the information collected changes, or when the required notice language is updated, and none of those events reaches you directly. Verifying not stated at the moment you download is the whole defence.
One thing this page does not do: tell you whether your submission will be accepted. We publish the document and explain how to complete it, and that is where our role ends. Nothing here is legal advice. Take questions about eligibility, applicability or procedure to not stated, to your servicing personnel office, or to the office named in not stated.
