According to AASHTO T 88, what is the accuracy requirement for material passing the 2.00mm (No.10) sieve?

The accuracy requirement for material passing the 2.00mm (No. 10) sieve, as specified in AASHTO T 88, is indeed 0.01 g. This standard establishes the precision needed for the measurement of fine aggregates when performing sieve analysis, particularly for materials used in construction and engineering projects.

Ensuring such a high degree of accuracy (0.01 g) is crucial because even minor variations can significantly impact material properties and, consequently, the performance of the aggregate in applications such as asphalt and concrete mixes. This level of precision helps in obtaining reliable data that contributes to the overall quality control of the materials being tested.

In contrast, the other options suggest lower accuracy levels that would not meet the stringent requirements set forth in AASHTO T 88 for this particular sieve. The testing of materials is heavily reliant on precise measurements, and lesser accuracy could lead to miscalculations in the proportions of aggregates, resulting in suboptimal material performance in construction applications.
