AASHTO R 83-17 (2021) PDF Download

The AASHTO R 83-17 (2021) standard outlines the guidelines and procedures for using a Superpave gyratory compactor (SGC) to prepare cylindrical test specimens. These specimens are used for various axial compression and tension performance tests.

The standard specifies that the test specimens should have a diameter of 100 mm and a height of 150 mm. This practice is applicable to different types of asphalt mixtures, including dense-, gap-, and open-graded mixtures, with maximum aggregate sizes of up to 37.5 mm.

By following the procedures outlined in this standard, the SGC can effectively compact the asphalt mixture to produce uniform and representative cylindrical test specimens. These specimens are then used in subsequent performance tests to evaluate the properties and characteristics of the asphalt mixtures, such as their resistance to compression and tension.
