Bituminous Material Viscosity And Adhesion

In this paper, the author chooses five heavy-traffic asphalts and two typical aggregates (limy stone and granite) to study the relationship between the viscosity and the adhesion, or between the component and the adhesion of the asphalts.Compared the results of Brookfield viscosity experiments with that of Water-boiling experiments, the conclusion can be obtained: The relationship between the viscosity and the adhesion of asphalts is not apparent; And the judgment of "higher is the asphalt viscosity, better is the adhesion" is under certain conditions.On the other hand, the results of asphalt four components analysis experiments indicate that using the ratio of Resin and Aspartames to evaluate the asphalt adhesion is reasonable and sound. At the same time, the author makes use of rectangular reference frame to analyze the correlation between the asphalt four components and the adhesion; and it can be concluded that the rectangular area of the asphalt four components in rectangular reference frame has good relations with the asphalt adhesion.
