AASHTO T 161-17 PDF Download

The AASHTO T 161-17 standard describes two procedures for determining the resistance of concrete specimens to repeated cycles of freezing and thawing in a laboratory setting.

Procedure A involves subjecting the concrete specimens to rapid freezing and thawing in water, while Procedure B involves rapid freezing in air followed by thawing in water. Both procedures are designed to assess the effects of various concrete properties on its resistance to freezing and thawing cycles as specified in each respective procedure.

It is important to note that these procedures are not intended to provide a precise quantitative measure of the expected service life of a specific type of concrete. Rather, their purpose is to evaluate how different variations in concrete properties can impact its resistance to rapid freezing and thawing.
