What technical requirements define polymer modified asphalt emulsion sealer at low temperature for asphalt or bitumen modification?

Polymer modified asphalt emulsion sealers for low-temperature applications must meet specific technical requirements. These include a minimum softening point of 50°C to ensure flexibility, a low-temperature ductility of at least 10 cm to prevent cracking, and a viscosity range of 500-3000 cP at 25°C for optimal application. Additionally, the emulsion should exhibit good adhesion properties and stability, with a polymer content of 3-5% to enhance performance under varying temperature conditions.
