    摘要: A mineral-compatible cationic emulsion composition with polymer stabilizers, and methods for utilizing same in paving and other applications is disclosed. In one aspect, a bitumen-in-water emulsion composition includes at least one bitumen material, at least one polymer stabilizer, at least one emulsifier, and water, where the emulsifier is a cationic surfactant, an amphoteric surfactant, or a mixture of both, and the polymer stabilizer is a natural or synthetic cationic polymer consisting of alkylene polyamines, alkyl polyamines, polyquaternary polymers, polyvinylamine, polyvinylimidazoline, polyester polyquaternary polymers, polyether polyquaternary polymers, or mixtures thereof. The inclusion of polymer stabilizer in the cationic emulsion increases the stability of the emulsion and increases the compatibility of the cationic emulsion with negatively charged minerals.
