Cationic Emulsions – McAsphalt

Cationic Emulsions. There are three major classifications of emulsion grades: rapid-setting, medium-setting, and slow-setting. The terms “rapid,” “medium,” and “slow” relate to the amount of time it takes for the emulsion to cure and the amount of mixing that can be performed before the emulsion breaks.

The Chemistry of Asphalt Emulsions

The emulsifier, when used in combination with an acceptable asphalt, good quality water arid adequate mechanical input, is the major factor which influences initial emulsification, emulsion stability arid ultimate field performance.

Tack Coat Guidelines

Cationic—Emulsified asphalt particles can be cationic (positively charged) and, in theory, should be used with aggregates carrying a negative charge. The type of emulsifying agent used in the asphaltic emulsion determines if the emulsion will be cationic or anionic. The principal difference in the two is that cationic emulsion gives up water ...
