Specifications BP Unmodified PG Binders are produced to meet the AASHTO M 320 and M332 specifications. Availability
increases the high temperature stiffness of an asphalt binder with only minor effect on the intermediate and low temperature properties. How is PPA Used The Superpave Performance Grade (PG) binder specification is used predominantly in the US. In the PG system the high and low temperature performance range is specified i.e., PG 64-22.
Superpave Binder Specification Low Temperature Characterization The Bending Beam Rheometer (BBR) determines the Creep Stiffness (S) of an . asphalt binder at low temperatures. If a binder is too stiff at service . temperatures, you can expect low . temperature cracking.
Stiffer binders may be required for certain mix types (e.g., both stone-matrix asphalt (SMA) and permeable friction course (PFC) require a minimum PG 76-XX binder) to insure reliable performance. Stiffer PG 70 or PG 76 binders are also commonly used for surface mixes in high traffic areas.

5.3. The asphalt binder shall be homogeneous, free from water and deleterious materials, and shall not when heated to 175°C. 5.4. The asphalt binder shall be at least 99.0 percent soluble as determined by T 44 or ASTM D5546. 5.5. This specification is not applicable for asphalt binders in which fibers or other discrete particles
The 'A' designation corresponds to the Performance Graded (PG) asphalt binder of PG 64-22 required in the mix. NMDOT "Standard" Base Mix As the name implies, the base mix is the base asphalt layer for the pavement structure. Its major function is to provide the principal support of the pavement structure.
A PG binder grade or source change will not require a new mix design. If the upper temperature classification of the PG binder is lower than the original PG grade, a new TSR value is required. The MAF equals the Gmm from the mixture design divided by the following: 2.465 for 9.5 mm mixtures and 2.500 for 12.5 mm, 19.0 mm, and 25.0 mm mixtures.

How is asphalt binder is defined in a PG System (the notation)? PG system is based on project climate. The standard notation for PG binder is
The Performance Graded (PG) system is a method of measuring asphalt binder performance. It was originally developed during the Strategic Highway Research Program (SHRP) in the early 1990s. In 2005, California agreed to adopt the PG system for grading asphalts in the state. The main purpose of classifying and selecting asphalt binders using the ...

In 1993, the Performance Graded (PG) asphalt binder specifications were introduced as part of the Strategic Highway Research Program (SHRP). The PG specifications were eventually adopted by the American Association of State and Highway Transportation Officials (AASHTO) and formally implemented by WSDOT in 1999.
(3) When a total PG Binder grade type on a project is less than 200 tons, a minimum of one PG Binder lot sample is required. If the PG Binder does not comply with test specifications, then the pay factor of the PG Binder lot shall be adjusted according to Table 1029.02, and Table 1029.03 (if modified).

Superpave performance grading (PG) is based on the idea that an HMA asphalt binder's properties should be related to the conditions under which it is used. For asphalt binders, this involves expected climatic conditions as well as aging considerations. Therefore, the PG system uses a common battery of tests (as the older penetration and viscosity grading systems do) but specifies that a ...
