Study on the Adhesion Properties of Asphalt-aggregate Interface Based on Pullout Test
The attenuation of adhesion between asphalt and aggregate is the main cause of pavement disease. The research on the interface between asphalt and aggregate is a hot issue to improve the performance of asphalt mixture and the durability of asphalt pavement. In this paper, Haiyun 70#, Haiyun 90# asphalt and limestone, basalt, granite and other aggregates as the research object, using the macro mechanical point of view of the drawing test, through testing the different degrees of aging asphalt and aggregate interface drawing strength, analysis of the interface adhesion properties of the change law, and then for the actual engineering to improve the adhesion of asphalt mixture to provide a reference. The results show that the drawing strength of 70# matrix asphalt and aggregate is greater than that of 90# matrix asphalt; The order of drawing strength of the three aggregates and bitumen is limestone > basalt > granite; Short-term aging can enhance the adhesion to a certain extent, while long-term aging can lead to a decrease in adhesion.
