Bitumen VG vs PG: Viscosity vs Performance Grades Explained
This guide breaks down how viscosity-graded (VG) and performance-graded (PG) bitumen systems work, why they differ, and when each spec is the smarter buy. Using Bitumen VG vs PG comparisons, simple selection steps, and real project scenarios, you’ll learn how climate, traffic, aging, and modification affect binder choice—plus what to request in lab tests and supplier documentation to avoid costly paving failures.
