Failure to conduct this test can result in:

The AASHTO T85 Specific Gravity and Absorption of Coarse Aggregate testing service provided by Eurolab involves the following steps:

1. Sample Preparation:

Aggregate samples are collected from construction sites or warehouses

Samples are cleaned, dried, and crushed to meet specific size requirements

2. Specific Gravity Measurement:

The sample is immersed in a calibrated container filled with distilled water

The volume of displaced water is measured using a burette or electronic balance

3. Absorption Measurement:

The sample is saturated with water, and the excess water is measured

The absorption value is calculated as the difference between the initial and final weights
