Which Performance Graded binder is classified as PG 76-22?

The classification of PG 76-22 refers to a Performance Graded binder that has been modified with polymers to enhance its properties. Polymer Modified Asphalt is designed to improve performance characteristics, such as resistance to deformation, cracking, and aging. The "76" in the designation indicates the high-temperature grading, which signifies its ability to withstand elevated temperatures without significant rutting, making it suitable for areas with heavy traffic loads and warmer climates. The "22" indicates the low-temperature performance grading, allowing the binder to perform adequately in colder conditions without becoming brittle.

In contrast, the other types of binders listed do not possess the same properties. Asphalt Rubber Binder incorporates recycled rubber but may not be classified specifically as PG 76-22. Standard Asphalt Binder typically lacks the polymer modification, resulting in different performance characteristics. Emulsified Asphalt consists of a mixture of asphalt cement and water, necessitating different handling and applications, thus falling outside the PG grading system.
