Abstract:
In order to assess the influences of asphalt component and composition on asphalt technical properties, thirteen types of pavement petroleum asphalts and two kinds of typical aggregates were selected. The relationship among asphalt component, viscosity and adhesion was investigated by using tests of four-component, apparent viscosity and adhesion. The characterization method of asphalt four-component test result by using triangular coordinate system was put forward. The asphalt characteristic triangle was drawn with four-component data. The characteristic of asphalt composition was represented by inertia moment. The asphalt pyramid was drawn based on asphalt four-component data and the relationship among its geometry characteristics, viscosity and adhesion was analyzed. Analysis result indicates that except asphalt components, its composition differences also have influences on asphalt viscosity and aggregate adhesion. For the asphalts with same penetration grade and different brands, triangular coordinate analysis result shows the aggregate adhesion increases with the increase of the inertia moment of asphalt four-component characteristic triangle. 6 tabs, 6 figs, 18 refs.
