What is the common practice regarding the reporting of Gmm and Gmb?

Reporting Gmm (maximum specific gravity of the mixture) and Gmb (bulk specific gravity of the mixture) to the nearest three decimal places is common practice because these measurements are crucial for evaluating the density and voids in the hot mix asphalt (HMA). The precision of three decimal places ensures that the data reflects accurate material properties, which is essential for quality control and the mix design process. This level of detail allows engineers and inspectors to identify issues or trends within the asphalt mix, ensuring that it meets the required specifications and performance criteria. It is important for maintaining consistency and reliability in documentation and contributes to effective decision-making in asphalt production and paving operations.
