How is pg 76 22 polymer modified asphalt applied in asphalt or bitumen modification processes?

PG 76-22 polymer modified asphalt is applied in asphalt modification processes by blending it with conventional asphalt binder. The modification typically involves heating the asphalt to a specific temperature, usually between 350°F to 400°F (about 175°C to 200°C), and then adding the polymer. This mixture is agitated to ensure uniform dispersion of the polymer throughout the binder. The resulting modified asphalt exhibits improved elasticity, temperature resistance, and durability, making it suitable for high-performance pavement applications.
