AASHTO T 84-13 (2017) PDF Download

AASHTO T 84-13 (2017) is a standard method of testing for the specific gravity and absorption of fine aggregate. The purpose of this method is to determine the bulk and apparent specific gravity, as well as the absorption of fine aggregate. The specific gravity and absorption values are important parameters for evaluating the quality and performance of fine aggregate in construction materials.

In this method, the specific gravity and absorption are determined by measuring the mass of the fine aggregate before and after soaking in water for a specific period of time. The bulk specific gravity is calculated based on the mass of the saturated surface-dry aggregate, while the apparent specific gravity is determined by dividing the mass of the oven-dry aggregate by its volume. The absorption is then calculated using the difference between the bulk and apparent specific gravities.

It is worth noting that this method conforms to the technical requirements of ASTM C 128-12, making it an internationally recognized standard. The use of standardized testing methods ensures consistency and comparability of results across different laboratories and testing facilities.
