1. An impact test fixture adapted to roll along a ground surface, the impact test fixture comprising:
- a rolling frame structure comprising a plurality of wheels for rolling along the ground surface;
a ballast attachment feature coupled to the rolling frame structure;
a position-adjustable attachment assembly coupled to the rolling frame structure;
a specimen attachment member coupled to the position-adjustable attachment assembly, the position-adjustable attachment assembly comprises a frame-side fixturing element coupled to the rolling frame structure, a first specimen-side fixturing element coupled to the frame-side fixturing element, and a second specimen-side fixturing element coupled to the frame-side fixturing element; and
at least one of the frame-side fixturing element or the first and second specimen-side fixturing elements is adjustable in at least one of a vertical direction and a transverse direction relative to the rolling frame structure such that the specimen attachment member is adjustable in the vertical direction and the transverse direction relative to the rolling frame structure.
