Describes the construction of a test fill of no-slump concrete placed by conventional rockfill placement methods and compacted with a 15 ton vibratory roller, The fill contained an untreated 24 hr old construction joint at the midheight of the 4 ft high by 16 ft wide by 32 ft tong fill. Twelve widely spaced vertical cores were taken from top of fiII into rock and t w o horizontal cores were taken through-out the 16 ft width at the construction joint. From these cores tests were performed on some 24 compression speci-mens, 16 tensile specimens, 25 shear specimens, and 8 permeability specimens. The results of these tests and condition of the concrete cores is described.
