Precision Statements for AASHTO T312 and other Laboratory Test Methods

The objectives of this research were to (1) develop a precision statement for the American Association of State Highway and Transportation Officials (AASHTO) T 312, Standard Method for Preparing and Determining the Density of Hot Mix Asphalt (HMA) Specimens by Means of the Superpave Gyratory Compactor; (2) update the current precision statements for AASHTO T 166, Bulk Specific Gravity of Compacted Bituminous Mixtures and ASTM D2041-00, Standard Test Method for Theoretical Maximum Specific Gravity and Density of Bituminous Paving Mixtures; and (3) develop a preliminary precision statement for determination of the bulk and maximum specific gravities of bituminous mixtures with the Corelok device.
