The results and analyses of a series of strain-controlled, consolidated-undrained (R) and unconsolidated-undrained (Q) triaxial compression tests performed on various gradatoins of artificially blended earth-rock mixtures and on a natural earth-rock mixture obbtained from borrow area F associated with the construction of DeGray Dam, Caddo River, Ark., are presented. The tests were conducted to determine the validity of two widely used modeling techniques in cases where available triaxial testing equipment sizes are smaller than those dictated by the maximum particle size of the full-scale gradation. The objective was achieved by comparing results of Q and R triaxial tests performed on 15-in.-diam by 38.5-in.-tall specimens of a full-scale gradation with those obtained from 6-in.-diam by 13.6-in.-tall specimens of scalped/replaced and scalped gradations derived from the full-scale gradation.
