AASHTO R 76-16 (2020) PDF Download

AASHTO R 76-16 (2020) is a standard method that focuses on the reduction of large samples of aggregate to the appropriate size for testing purposes. The objective of this standard is to ensure that variations in measured characteristics between the test samples and the large samples are minimized. By following the techniques prescribed in this standard, test samples can be obtained that accurately represent the properties of the larger aggregate sample.

This standard, previously known as test method T 248, provides guidelines and procedures for reducing the sample size in a consistent and reliable manner. The specified techniques aim to minimize any potential discrepancies between the test samples and the original large sample, ensuring accuracy and consistency in subsequent testing. Adhering to this standard helps in maintaining quality control and assurance in aggregate testing processes.
