GOST 22733-2016 PDF

Full title and description

GOST 22733-2016 — "Грунты. Метод лабораторного определения максимальной плотности" (English: Soils. Laboratory method for determining of maximum density). The standard specifies the laboratory procedure for determining the maximum dry density of soils and the corresponding optimum moisture content using the standard (rammer) compaction method for geotechnical and construction investigations.

Abstract

This interstate (GOST) standard establishes a laboratory method to determine the maximum dry density (standard density) and corresponding optimum moisture of natural and man‑made dispersive soils by standard compaction in a mould (layered compaction with a specified rammer energy). It replaces the former GOST 22733-2002 and is intended for use in soil characterization for construction and earthworks.

Scope

The standard applies to natural and technogenic (man‑made) dispersive soils and sets out the laboratory procedure to determine: (1) the maximum dry density (the greatest dry density achievable under the standard compaction energy) and (2) the optimum moisture content corresponding to that maximum density. The method is used when investigating soils for foundations, embankments, road bases and other construction works where compaction characteristics are required. The standard defines sample preparation, apparatus, compaction technique (layered compaction), number of blows, calculation formulas and reporting requirements.

Key topics and requirements

• Definition of maximum dry density (standard density) and optimum moisture content for soils under specified compaction energy.
• Required apparatus and mould/rammer dimensions and masses for standard compaction tests.
• Sample preparation, subdivision and moistening procedure before compaction.
• Compaction procedure: layered compaction (typically three layers) with prescribed number of blows per layer and specified rammer drop height/energy.
• Calculation methods to obtain dry density from measured wet mass and moisture content; plotting compaction curve to determine maximum and optimum moisture.
• Reporting format, tolerances, and reference to normative documents used for ancillary tests (particle-size, liquid/plastic limits, water content determination).
• Normative references to related GOSTs and test methods that provide supporting definitions and lab procedures.

Typical use and users

Primary users are geotechnical engineers, soil testing and construction materials laboratories, design institutes, road and earthworks contractors, and regulatory/inspection bodies who require laboratory-derived compaction parameters for design, specification and quality control of compacted layers (foundations, embankments, road bases). Research and educational laboratories in geotechnics also use the method.
