To what temperature should gradation samples be dried in an oven?

• A. 200 ± 5 F
• B. 230 ± 9 F
• C. 210 ± 10 F
• D. 240 ± 12 F

Answer: (B)

The correct temperature for drying gradation samples in an oven is 230 ± 9 F. This temperature range is established to ensure consistent and reliable results when testing aggregate materials. Drying at this temperature helps to eliminate moisture without excessively heating the sample, which could alter its physical properties or lead to inaccurate gradation results. Maintaining this specific range is critical for standardizing processes in laboratory settings, especially in construction and materials testing. The other temperature options, while they may seem reasonable, fall outside the established standards for drying gradation samples. Each of those temperatures could either risk compromising the integrity of the samples or not adequately remove moisture, leading to potential inaccuracies in the gradation analysis. Therefore, the chosen temperature of 230 ± 9 F aligns with industry best practices for obtaining precise and dependable test results.
