AASHTO R 47-14 PDF Download

The AASHTO R 47-14 standard provides guidelines for reducing large samples of HMA to a suitable size for testing purposes. The main objective of this practice is to ensure that the measured characteristics of the test samples accurately represent the properties of the larger sample.

The standard specifies various techniques that can be used to achieve sample reduction while minimizing variations in the measured characteristics. These techniques aim to maintain the integrity of the sample and prevent any bias in the testing results. By following the guidelines outlined in the standard, users can ensure that the testing size samples accurately represent the overall characteristics of the HMA.

This standard is crucial in the field of asphalt testing as it provides a standardized approach to reducing samples, allowing for consistent and accurate results. It serves as a valuable resource for laboratories, construction firms, and researchers involved in HMA testing, ensuring that the samples used in testing are representative and reliable.
