Asphalt Materials, Components And Viscosity Test

This paper select thirnteen heavy-traffic asphalts and two typical aggregates (lime and basalt) to study the relationship among asphalt component, viscosity and the adhesion of the asphalts.The test results of brookfield ratotional viscosity at different temperature and grey correlation analysis of asphalt component indicate that viscosity has good relations with the colloid level.Asphalt four components analysis experiments indicate that the colloid level and the bituminous level are the important factors of pavement performance.At the same time,using triangular coordinate system and triangular pyramid plot to analysis the correlation between Asphalt four components and the adhesion.Test results indicated that under triangular coordinate the larger of area moment of the same grade asphalt,the better adhesion of the asphalt, during triangular pyramid the smaller of triangular pyramid area of the same grade asphalt,the higher of viscosity at 135℃, the better adhesion of the asphalt.
