What technical requirements define polimer modified asphalt emulsion for asphalt or bitumen modification?

Polymer modified asphalt emulsion must meet specific technical requirements, including viscosity, stability, and adhesion properties. The emulsion should exhibit a stable particle size distribution and a minimum storage stability of 24 hours. Additionally, it should have a high polymer content (typically 3-5%) to enhance elasticity and temperature susceptibility. The pH level should be neutral to prevent degradation, and the emulsion should demonstrate compatibility with various aggregates and existing asphalt materials for effective modification.
