AASHTO T 354-17 PDF Download

The AASHTO T 354-17 standard provides guidelines for determining the bulk and apparent specific gravity and absorption of both fine and coarse aggregates. The test is conducted at a controlled temperature of 20 ± 1°C (70 ± 2°F) and can be performed on dry and saturated aggregates.

The purpose of this standard is to accurately measure the specific gravity and absorption properties of aggregates, which are important factors in determining the quality and suitability of the material for various construction applications. The specific gravity of an aggregate indicates its density relative to the density of water, and the absorption value represents the amount of water that can be absorbed by the aggregate.

The test method employed in this standard is the volumetric immersion method, which involves immersing the aggregate in water and measuring the volume of water displaced by the sample. By comparing the volume of water displaced by the aggregate to the weight of the sample, the bulk and apparent specific gravity and absorption properties can be determined.
