Abstract

Abstract: Polymer modified asphalt emulsions offer superior performance and lifespan as compared to conventional asphalt emulsions or hot mix asphalt surface treatments, as well as reduced life cycle costs. This study's objective was to examine the characteristics of latex-modified asphalt emulsions using a range of tests, including those for softening point, penetration, ductility, viscosity and solubility. In order to determine the optimal latex modified asphalt emulsion, latex was added into emulsion type CSS-1hP at various ratios ranging from 1 to 9 percent, with 2 percent interval while 0 percent serving as the control. From the experiments described, the best latex modified asphalt emulsion measurement was selected using a decision matrix analysis. Decision Matrix Analysis was performed to determine that asphalt emulsion with 5 percent latex is the best choice since it offers the highest quality polymer modified asphalt emulsion.
