Full Name
AASHTO T325 – Standard Method of Test for Estimating the Strength of Concrete in Transportation Construction by Maturity Tests
Scope
This standard provides procedures for estimating concrete strength in roads, bridges, and other transportation structures through the use of a maturity index.
This standard requires determination of the strength-maturity relationship of the approved concrete job mix in the laboratory and determination of the temperature history subsequent to placement in the field.
