standard by American Association of State and Highway Transportation Officials, 2020



AASHTO TP 138-20 covers procedures for determining the unit weight and diameter of steel wire and welded wire reinforcement, plain and deformed, for conformance with M 336M/M 336. A representative specimen of wire is tested to determine its diameter and/or unit weight. The tests herein described are used to determine the minimum properties of the wire in the product manufacturing specifications where indicated. Variations in testing methods are to be avoided and standard methods of testing are to be followed to obtain reproducible and comparable results.
