The visco-flow properties of asphalt in the aging process are analyzed.
- class="label">•
The visco-flow activation energy (Eη) is used to evaluate the visco-flow property of asphalt.
- class="label">•
Eη increases continuously with the deepening of aging.
- class="label">•
Eη shows a good negative correlation with the rate of creep stiffness (m).
- class="label">•
Eη shows a good linear correlation with colloidal instability index (Ic).
