Asphalt emulsions are widely used for the surface treatment of pavements. The quality of the asphalt binder and emulsion dictate the constructability, quality, and durability of the surface treatment. There are very limited test methods and specifications that are used to describe the quality of the asphalt emulsion for use in the surface treatment.
This breaking rate meter provides a simple tool that can be used in the field to measure the breaking rate and total breaking energy of the emulsion. Test results indicate that this tool can identify whether the emulsion is cationic or anionic, whether it is partially broken, and whether it has significantly higher or lower viscosity than desired. This technique also provides an indirect estimate of the asphalt content in the emulsion.
