Abstract: Asphalt emulsion is manufactured by the emulsification of asphalt, and is an energy-saving, ecologically safe material because it does not need any heating processes with gas emission and fire hazard in its use. The purpose of this study is to evaluate the feasibility of the use of an asphalt emulsion as a polymeric admixture. Asphalt-modified mortars using an experimentally manufactured asphalt emulsion are prepared with various polymer-cement ratios, and tested for strengths, adhesion, water absorption and permeation, carbonation and chloride ion penetration. As a result, the waterproofness, carbonation resistance and chloride ion penetration resistance of the asphalt-modified mortars are markedly improved with an increase in the polymer- cement ratio, but their compressive strength and adhesion to mortar substrates are reduced with increasing polymer-cement ratio. Therefore, it is recommended to control their polymer-cement ratio to be 10% or lower in their practical applications. Further study to improve their compressive strength and adhesion is needed.
