AASHTO PP 60-14 (2016) PDF Download

AASHTO PP 60-14 (2016) is a standard practice that outlines the procedures for preparing cylindrical performance test specimens using the Superpave Gyratory Compactor (SGC). The purpose of this practice is to provide a standardized method for preparing test specimens for various performance tests involving hot mix asphalt (HMA). The test specimens are cylindrical in shape, with a diameter of 100 mm and a height of 150 mm.

The practice is specifically designed for dense-, gap-, and open-graded HMA with maximum aggregate sizes up to 37.5 mm. It is important to note that this practice is not applicable to other types of asphalt mixtures or mix designs.

The Superpave gyratory compactor (SGC) is the specified equipment for this practice. The compactor is used to compact the HMA mixture into the cylindrical test molds under controlled conditions. The compaction process aims to simulate the field conditions and achieve the desired density and stability of the specimens.
