AASHTO T 103-08 (2021) PDF Download

The AASHTO T 103-08 (2021) standard provides procedures for testing the resistance of aggregates to disintegration caused by freezing and thawing. These procedures are useful in assessing the soundness of aggregates when information from service records is insufficient or unavailable.

The standard describes three testing procedures that can be used to evaluate the performance of aggregates under weathering conditions. By subjecting the aggregates to freezing and thawing cycles, the standard aims to determine their ability to withstand these environmental stresses without significant disintegration.

It should be noted that the standard provides guidelines for rounding off observed or calculated values. The values should be rounded to the nearest unit in the final decimal place specified in the standard, following the rounding-off procedure outlined in R 11. This ensures consistency and accuracy in determining compliance with the specified limits outlined in the standard.
