Defense Department form, series DD, number 1218. Full title: DD Form 1218, Marshall Method - Computation of Properties of Asphalt Mixtures, December 1965. Function: Marshall Method - Computation of Properties of Asphalt Mixtures. Edition in force: not stated. Publisher status: not stated.
Governing directive: not stated. Responsible office: not stated. The DD designation signals joint scope — all military departments, combatant commands and defense agencies draw on a single edition of the document.
Common users: service members regardless of branch, Defense civilian staff, and the offices that file, verify or retain the finished document.
Submission follows the schedule set by not stated and by local implementing procedures. This page provides the blank form for download and general orientation only.
The download set covers PDF. Document length is 1 pages with about 200 entry fields.
Distribution centres on pdf. Two states exist: fillable, where field boxes accept keyboard input and retain it, and printable, a static blank produced for manual completion. Typed data reproduces cleanly across copies; handwritten data depends on the writer.

Order of completion: identification block first, substantive entries second, certification and signature last. The blank is laid out in that sequence and the sequence is not arbitrary — later entries often depend on data established in the header.
Edition in use: not stated. Because DD forms are revised at Department level and distributed to all services at once, an obsolete printing may not match the fields an office expects. The date is printed on the form face.
Guidance for specific entries sits on the form face and in not stated; the directive is authoritative where the two do not agree.
After completion, the copy goes to the office designated by not stated or by local procedure. Retention of a personal copy is ordinary practice and costs nothing.
Cross-referenced forms are found through the numbering system. The DD sequence is Department-level and unified, which means a number cited on the page identifies one document across the whole Department.
A DD number and a DA number may appear in the same instruction without being related. DA forms belong to the Army alone; DD forms belong to the Department and are administered at Department level. The sequences are independent.
Revision occurs when the prescribing directive is reissued, when the data collected changes, or when statutory notice language is amended. Verification of the edition date at download addresses all three.
Scope of this page: distribution of a published form and description of its contents. It offers no legal guidance and no assurance regarding any particular submission. Direct procedural questions to not stated, to the servicing personnel office, or to the office designated in not stated.
