AASHTO R 66-16 (2020) PDF Download

AASHTO R 66-16 (2020) provides guidelines for sampling asphalt materials at various stages of production and handling. The standard applies to sampling at production facilities, storage facilities, and at the point of delivery. It covers the sampling of asphalt materials stored in tanks, stockpiles, vehicles, or containers used for storage or transportation purposes.

This practice ensures that representative samples are obtained for testing and analysis, allowing for accurate and reliable assessment of the quality and properties of the asphalt materials. The standard helps to maintain consistency in the sampling process, facilitating comparability of results and ensuring that the sampled materials are in compliance with the specified requirements.

It is noteworthy that AASHTO R 66-16 (2020) is an updated version of the standard, which was previously designated as test method T 40. The new designation reflects its change in scope from a test method to a practice for sampling asphalt materials.
