ASTM WK26800

    Work Item: ASTM WK26800 - New Test Method for Asphalt Mixture Shear Measurement by the Gyratory Pressure Distribution Analyzer GPDA Method

    (What is a Work Item?)

    Developed by Subcommittee: D04.20 | Committee D04 | Contact Staff Manager



    1. Scope

    1.1This test method uses the Gyratory Pressure Distribution Analyzer (GPDA) Plate to measure the resistive forces of a bituminous mixture during compaction as a means to estimate mixture workability and stability.

    Use of this testing method is becoming more accepted. A standard procedure is needed for existing and new users to understand the proper measurement technique
