### **Appendix A**

The specific gravity values of the fine-grained soil–TDA mixtures—that is, *G*STs calculated by Equation (3)—for the compiled database are presented in Table A1.

Note: *f* T = TDA content (i.e., TDA-to-soil dry mass ratio, here expressed as a percentage value); *G*Ss and *G*Ts = specific gravity of soil solids and TDA particles, respectively; and *G*STs= specific gravity of soil–TDA mixture (Equation (3)).

Figure A1 illustrates the variations of the conventional OMC and MDUW parameters, *<sup>w</sup>*op<sup>t</sup> and *γ*dmax, against TDA content *f* T for the 21 fine-grained soil–TDA compaction datasets.
