文摘

The multiple effects of water on the healing potential of bitumen were observed. Healing temperature is more important than healing time in bond strength recovery. Modifiers can affect the healing performance of bitumen. SBS modifier has the negative effect on the healing potential of the base bitumen. Aging process exerts distinct impacts on the base bitumen and modified binder. Three healing stages were suggested to interpret the healing behavior of bitumen: gathering, moving and rounding.
