AASHTO PP 76-13 (2020) PDF Download

AASHTO PP 76-13 (2020) is a standard practice that outlines the process for troubleshooting volumetric differences in asphalt specimens between Superpave Gyratory Compactors (SGCs) used in the design and field management of Superpave mixtures. This standard provides guidance on evaluating and comparing the performance of different SGCs, specifically the one used in the mix design, the one used for production quality control (QC), and the one used for production quality assurance (QA).

The purpose of this evaluation is to identify any variations or discrepancies within the compaction process that could potentially affect the field management of asphalt mixtures. By comparing the results from different SGCs, any inconsistencies in volumetric properties can be identified and addressed. This standard practice aims to ensure that the asphalt mixtures produced in the field are consistent with the design specifications, improving the overall quality and performance of the asphalt pavement.
