Optimal parameter combination scheme and sensitivity sequence of strength stability in later stage of cold feed.
| | Performance index | Design parameters | Parameter sensitivity ranking | | Design void ratio | Tackifier content | Diluent content | Antistripping agent content |
| | Initial strength | 2 | 3 | 1 | 3 | Diluent > void ratio > tackifier > antistripping agent | | Late stability (1 h) | 2 | 3 | 1 | 3 | Void ratio >> diluent > antistripping agent > tackifier | | Late stability (48 h) | 2 | 3 | 1 | 3 | Void ratio >> tackifier > antistripping agent ≥ diluent | | Residual stability | 3 | 3 | 3 | 3 | Tackifier > antistripping agent > diluent > void ratio |
