Petra Oil’s PG 70-28 is an ultra-high-performance asphalt binder specifically engineered for regions facing extreme temperature variation—from scorching summer heat to severe winter cold. Designed in full compliance with Superpave performance grading standards, PG 70-28 delivers superior long-term pavement durability by combining high resistance to rutting at elevated pavement temperatures (up to 70°C) with excellent low-temperature flexibility down to -28°C.

PG 70-28 is ideal for high-value roadway infrastructure that must endure heavy traffic loads and the most demanding climate conditions. With outstanding resistance to both thermal cracking and surface deformation, this binder offers dependable performance in the harshest environments—making it a preferred choice for northern regions, mountainous terrains, and areas subject to deep freeze-thaw cycles.

Manufactured to exceed AASHTO M320 requirements, PG 70-28 offers consistent quality and optimal binder behavior under thermal stress, ensuring reliable pavement performance and extended service life.
