AASHTO PP 92 – Standard Specification for Preparation of Test Specimens Using the Plastic Mold Compaction Device

AASHTO PP 92-19 (2020) covers the use of the plastic mold compaction device (PM device) to prepare cylindrical test specimens with an approximate 2:1 height-to-diameter aspect ratio for use in a variety of mechanical property testing (e.g. compressive strength, elastic modulus, tensile strength). This practice is intended for chemically stabilized soil materials (e.g. soil-cement). This standard practice can be performed in a laboratory, or, if performed at a construction site, may produce comparable properties.
