Functional chemical additives improve the high and low temperature properties and storage stability of SBS modified asphalt through chemical bonding. In the functional chemical additives +SBS modified asphalt system, the chemical bonding action of functional chemical additives causes the SBS molecular chains dispersed in the asphalt system to form a three-dimensional network structure, and forms a network structure with the asphalt system.


Such chemical mesh is not easy to destroy under high temperature, low temperature, needling, stretching and other conditions, and has excellent physical properties and storage stability. Therefore, the addition of functional chemical additives can significantly improve the high and low temperature properties and storage stability of SBS modified asphalt.


Specifically, the addition of functional chemical additives can improve the softening point, low temperature flexibility, needle penetration, 5℃ ductility and storage stability of SBS modified asphalt. In addition, the addition of functional chemical additives can also reduce the temperature of asphalt modification processing, shorten the processing time of asphalt modification, save production costs, and improve production efficiency.
