AASHTO PP 48-03 (2005) PDF Download

The AASHTO PP 48-03 (2005) standard provides guidance and instructions for assessing the internal angle of gyration of the Superpave Gyratory Compactor (SGC). The SGC is a machine used in the development of asphalt mixtures for road construction.

The standard focuses specifically on the evaluation of the internal angle of gyration, which is a measure of the compaction behavior of the asphalt mixture during the gyratory compaction process. The evaluation is carried out using the U.S. Federal Highway Administration Dynamic Angle Validation Kit (DAV).

The DAV is a tool designed to measure and validate the angle of gyration within the SGC. It helps ensure that the compactor is operating within the specified range and producing consistent and reliable results. The standard provides detailed instructions on how to perform the evaluation using the DAV and specifies the acceptance criteria for the angle of gyration.
