Research on Physics Stability of Emulsified Asphalt Modified by Nano Silica

Abstract

At present, research on nano-modified asphalt and asphalt mixture has made some achievements. This article applies the stabilization mechanism of pickering emulsion to prepare emulsified asphalt, and uses nano silica particles as emulsifier. On this basis, we further investigate the physical stability of emulsified asphalt modified by nano silica through analyzing and studying the sieve residue and storage stability, and establish a solid basis for subsequent development and further research.
