Abstract
• Recommended particle size for unmodified and modified cationic rapid set (CRS) asphalt emulsions were presented. • Links to performance with aggregate and asphalt emulsion quality were analyzed. • For CRS-2 asphalt emulsion, we recommend a mean particle size of 1.9 µm. • For CRS-2L asphalt emulsion, we recommend a mean particle size of 3.0 µm. • For CRS-2P asphalt emulsion, we recommend a mean particle size of 10.7 µm. Preliminary particle size specifications have been developed on Cationic Slow Set (CSS) and Cationic Medium Set (CMS) emulsions. Therefore, there is a need for a particle size standard specification for asphalt emulsions that encompass Cationic Rapid Set (CRS) with additives such as solid polymer and latex polymer. This research links particle size metrics to quality-control tests and a performance test for CRS-2, CRS-2P, and CRS-2L asphalt emulsions. The moderate correlation between storage time, viscosity, and particle size led to recommend a mean particle size of 1.9 µm for CRS-2, 3.0 µm for CRS-2L, and 10.7 µm for CRS-2P.
