Precision Statements for AASHTO Laboratory Test Methods

The objectives of the research are to: (1) develop a precision statement for AASHTO T312, "Standard Method for Preparing and Determining the Density of Hot Mix Asphalt (HMA) Specimens by Means of the SHRP 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.
