Grey Correlation Entropy Analysis of Influence Factors on the Strength of Emulsified Asphalt Mixture

Based on the modified Marshall test method,grey correlation entropy is applied to analyze the main factors such as cement content,aggregate gradation characterized by fractal dimension,asphalt content,volume of air voids in emulsified asphalt mixture,density of emulsified asphalt mixture and asphalt saturation influencing the strength of emulsified asphalt mixture.The results show that cement content and volume of air voids in emulsified asphalt mixture have a great effect on the strength of emulsified asphalt mixture.In the mix design and construction of emulsified asphalt mixture,these two factors should be strictly controlled.
