What is DD Form 1218? It is a Department of Defense form titled DD Form 1218, Marshall Method - Computation of Properties of Asphalt Mixtures, December 1965, and its job is straightforward: Marshall Method - Computation of Properties of Asphalt Mixtures. That single line covers most of what people want to know before they download it.
Is there a version specific to your service? No. A DD number is issued at Department level, which is the whole point of the prefix — every military department and defense agency works from one identical document. Looking for a branch variant wastes time you do not have.
Who decides this form exists? not stated owns it; not stated directs its use. If someone told you to file this, the authority traces back to those.
Is this the right edition? The current one is dated not stated, and the publisher carries it as not stated. Check that against whatever copy you already have before going further.

Download the form
Which files are here? These: PDF. How much work is involved? 1 pages, about 200 entry fields.
Do you pay for these? No. Free download, every format. What should you avoid? Filling the form inside a browser tab; the fields frequently do not save.
In what order do you complete it? The printed order, top to bottom. Header data comes before the body, and the body before the signature block. The sequence is not decorative — later entries are keyed to earlier ones.
Why does the edition matter so much here? Because DD forms are revised centrally. When the Department reissues one, it reissues it for all branches simultaneously, and the field layout can shift. Compare the printed date against not stated before you type anything.
Where do you look up an unclear entry? The form face first, not stated second. And when the two disagree? not stated controls.
Where does the completed form go? To the office named in not stated or in your organization's local procedure. Should you keep a copy? Always — a scan or a saved file costs nothing and spares you the whole exercise if the original disappears.
Do you need to know which branch issued a related form? No. DD numbering is Department-wide and unified, which means the number on its own is a complete address for the document.
Do DA and DD numbers ever correspond? Never. DA numbering is Army-specific, administered by an Army proponent, while DD numbering is Department-wide under not stated or an equivalent Department office. Identical digits in the two systems mean two unrelated documents, which is why the prefix matters more than the number.
How often does a form like this change? Unpredictably — revision follows directive changes, altered collection requirements and updated notice language. What is the practical defence? Verifying not stated every time you download rather than trusting a saved copy.
Will your completed form be accepted? That is not a question this page can answer. What you have here is a published Department of Defense document, a description of it and instructions for filling it out. Nothing on the page is legal advice, and nothing here determines what any office does with a submission. Where do the remaining questions go? To not stated, to your servicing personnel office, or to the office named in not stated.
