^aReference stress 100 kPa, tabulated values extrapolated with stress exponent m = 0.45 from 20 kPa cell pressures from the multilevel triaxial test

^bIndicates need for further compaction

^cTriaxial test conducted only with single cell pressure of 40 kPa

^dMaximum dry density with Proctor test = 2100 kg/m³; rock density = 2650 kg/m³

^eMaximum dry density with Proctor test = 2230 kg/m³; rock density = 2650 kg/m³
