What Is PG 76-34 Performance Grade Bitumen?
PG 76-34 is a Superpave performance-graded bitumen built for a 110°C temperature span — the widest in the PG76 range — resisting rutting up to 76°C while staying flexible and crack-resistant down to -34°C. This span makes it one of the most heavily polymer-modified grades in the lineup.
It’s specified for highways and freight corridors in continental or sub-arctic climates, where hot pavement surfaces in summer and severe sub-zero winters threaten pavement integrity. High polymer content improves elastic recovery and ductility, reducing thermal cracking risk during cold snaps.
Certified to AASHTO M320 / ASTM D6373 Superpave standards, PG 76-34 is the grade of choice when a project’s climate data shows both heavy traffic stress and extreme seasonal cold.
