Calculation results of asphalt colloid instability index.
| Aging state | SBS asphalt | 3% Z + 25% T + SBS asphalt | Ic | Ic increment | Ic | Ic increment |
| Before aging | 0.346 | — | 0.340 | — | RTFOT | 0.385 | 0.039 | 0.350 | 0.009 | PAV | 0.534 | 0.188 | 0.446 | 0.096 | UV | 0.524 | 0.178 | 0.456 | 0.115 |
