In order to study the correlation between the four components of matrix asphalt and conventional indexes,this paper separate the four components of asphalt,and analyzes the effect of different components on softening point,penetration,ductility and 60 ℃ dynamic viscosity mainly by Solvent Precipitation and Chromatographic Column Adsorption Method.Using multiple linear regression analysis method,the regression equation between the four components of asphalt and conventional indexes,correlation coefficient R,F value,probability P value and error variance value are established,and partial residual diagram and fitting diagram are drawn.The experimental results show that the four components of matrix asphalt determine the parameter indexes of asphalt.The four component content of asphalt has significant correlation with the conventional indexes of different brand matrix asphalt.Therefore,in the production and application of asphalt,we should pay attention to the performance of matrix asphalt and the proportion of four components.
