Abstract
To test self healing capability of asphalt binders, three asphalt specimens (pure asphalt, modified asphalt and aged asphalt) were prepared. Every specimen was tested by dynamic shear rheometer (DSR). The temperature sweeps result indicates that both aging and SBS modifying influence the self healing capability of asphalt binder. The fatigue-heal-fatigue test was introduced to study the self healing capability of asphalt in its serving periods. Furthermore, three different periods (0.5 h, 1 h, 3 h) were set up to study the influence of rest time on fatigue time. It is concluded that longer rest time, less load will delay the appearance of cracks and extend the service life of asphalt binders.
