Experimental study of binder-filler interaction using the modified multiple stress-strain creep recovery test

Rutting has the potential to lead to hazardous driving conditions and is a concern for the asphalt community. Asphalt mixture behaviour is significantly governed by the properties of the used bitumen. Because of the increasing demand for better performance, current studies have tended to focus on developing rheological binder tests that can be used to accurately predict asphalt performance especially for modified binders. In addition, there is an essential requirement to consider the interactions between components in an asphalt mixture. This paper presents a new procedure to characterise the creep and recovery properties of pure bitumen and mastics using a modified multiple stress-strain creep recovery test. To understand the authentic mechanism of rutting resistance, two new factors comprising ‘time factor’ and ‘normalised recovery’ are introduced. The results indicate that creep and recovery are functions of filler concentration, stress level, strain level and temperature.
