Abstract: In order to analyze the influence mechanism of solid waste micro-powder materials on asphalt performance, solid waste silica fume, as well as hydrated lime and cement micro-powder commonly used for roads, were selected as representatives to analyze the micro-powder surface energy, modified asphalt surface energy, surface topography, surface mechanical performance and asphalt component through tests such as capillary rise method, droplet method and atomic force microscope (AFM), which are on the basis of the type, dosage and particle size of the materials. And verified the high and low temperature performance of micro-powder modified mixtures. The results indicate that adding micro-powder can improve the polar component of asphalt and increase its surface energy, and the surface energy increases more significantly with the increase of dosage and the decrease of particle size. The saturation fraction in the four components of asphalt gradually decreases with the increase of micro-powder dosage and the decrease of particle size, and the adhesion force Fa(min) of the modified asphalt also gradually increases. This work proposed that the surface content S of micro-powder materials in asphalt is the core characteristic parameter affecting asphalt perfor-mance, and the logarithmic relationship between micro-powder surface area and asphalt components and surface energy was established. Micro-powder on the asphalt mixture of high-temperature performance is favorable, the low-temperature performance is unfavorable, but with the particle size decreases, the degree of adverse effects gradually reduces. The findings provide theoretical support for the prediction of asphalt modification performance of micro-powder materials.
