Emulsified asphalt has been widely used in various surface-treatment methods, such as chip seal, for low-volume roads preservation. It is widely used because of environmental and economic concerns. There is still no agreement about the standard method, especially the standard test conditions and the critical parameter values, to evaluate the performance of the emulsified asphalt residue. More attention should be paid to the performance of residue after water was removed from the emulsified asphalt because the performance of residue related to the characteristics during the service period, not just the property evaluated with the current standard method during the production and storage stage. This paper is motivated by current emulsified asphalt test methods, which mainly focused on emulsified asphalt during the production and storage stage. Based on current test methods there are limited residue performance evaluations. There is no performance-grade (PG) evaluation system on emulsified asphalt residue. The objective of this paper is to evaluate the performance of emulsified asphalt residue, which focused on the PG of the residue. This paper will mainly focus on the performance of four emulsified asphalt residues commonly used in Minnesota and Michigan based on the PG system. The emulsified asphalt residue was acquired by conducting the emulsified asphalt distillation procedure. The effectiveness of distillation test conditions will be evaluated.
