What is the required amount of mix for Gmm (rice) samples?

The required amount of mix for Gmm (Bulk Specific Gravity) samples is indeed in the range of 2000-2200 grams total. This quantity ensures that there is enough material to fill both flasks used in the testing process adequately, allowing for accurate measurement and analysis of the specific gravity of the asphalt mixture.

Using this amount helps guarantee that the test results are representative of the mix being analyzed, as it provides sufficient sample volume to account for any potential variability within the material. Accurate Gmm testing is critical for determining the appropriate proportions and performance characteristics of the asphalt mix.

Choosing this specific range supports the standard practices for asphalt testing, facilitating a reliable assessment of the material's properties, which are essential for quality control throughout the construction process.
