Abstract

In order to study the influence of test condition on rheological property of asphalt combined binder, the paper uses five kinds of filler-bitumen ratio and different temperature condition.by the rheological test, it studies the asphalt combined binder on n the high-low temperature and fatigue performance. The result indicates that mineral powder can strength the high temperature performance, but it is bad for low temperature performance and fatigue performance; when test temperature is more higher, it’s high temperature performance and fatigue performance weaker, but it’s low temperature performance strength; co nsidering the high-low temperature and fatigue performance, it suggests the reasonable filler-bitumen ratio range is 0.8-1.0.
