Here is a breakdown of the exact procedure as outlined in the official AASHTO T182 standard. Follow these steps precisely to achieve repeatable, accurate results.

| Error | Consequence | Solution | |-------|-------------|----------| | | Non-representative results, especially with gravel | Follow minimum mass table exactly | | Oven overcrowding | Uneven drying, prolonged time | Leave space between containers | | Not covering the container during cooling | Absorption of atmospheric moisture, causing lower water content | Always use lids or a desiccator | | Drying organic or gypsum soil at 110°C | Oxidation of organic matter or loss of crystal water → falsely high water content | Dry at 60°C | | Assuming constant mass without verification | Partial drying leads to under-reported water content | Perform check weighing after 2 more hours |

Every DOT specification (e.g., Caltrans, FDOT, TxDOT) requires water content determination using AASHTO T182 or an equivalent. Without the PDF, you cannot defend your results in a dispute or arbitration. aashto t182 pdf
