Performance Graded Binder
Performance Graded (PG) Binder is a specially formulated asphalt mix designed to perform well under specific climate conditions, such as temperature extremes and traffic loads. It is tested and assigned a "grade" that indicates its suitability for a region—e.g., PG 64-22 means it remains flexible and durable at certain high and low temperatures. This grading helps engineers select the right binder to ensure roads are strong, flexible, and long-lasting in different weather conditions, improving pavement performance and reducing maintenance costs.
