AASHTO T 103-08 (2017) PDF Download

The AASHTO T 103-08 (2017) standard provides guidelines for testing the resistance of aggregates to disintegration caused by freezing and thawing. This standard includes three procedures that can be used to assess the soundness of aggregates, particularly in cases where information about their performance in service is lacking.

The purpose of conducting these tests is to gain information about the durability of aggregates when exposed to weathering conditions. By subjecting the aggregates to freezing and thawing cycles, the standard aims to determine their ability to withstand such environmental factors.

The standard also provides guidance on rounding off observed values or calculated values to the nearest unit. Compliance with the specified limits in the standard should be determined by rounding off the results in accordance with the rounding-off rules outlined in reference R 11.
