Full title and description

St ASTM D5519-25 — Standard Test Methods for Particle Size Analysis of Natural and Man‑Made Riprap Materials. This standard defines four alternative procedures for determining the particle size distribution (gradation) and mass characteristics of riprap, armor stone, filter bedding and related coarse materials used for erosion protection and revetments.

Abstract

ASTM D5519-25 provides standardized test methods to determine particle size distribution and mass characteristics of natural and manufactured riprap and related coarse materials. Four alternative methods (A, B, C, D) are described to accommodate a range of sample sizes, handling capabilities and precision needs. The standard applies to particles nominally 3 in. (75 mm) and larger and includes guidance on data reporting, units, and relevant safety considerations.

General information

• ICS / categories: ICS 19.120 (Soils and rocks / geotechnical engineering); Book of Standards Volume 04.08; developed by Committee D18 (Subcommittee D18.17).
• Edition / version: D5519-25 (2025).
• Number of pages: 11 pages.

Scope

These test methods cover particle size and mass analysis for natural and man‑made riprap and related materials (including filter stone and coarse bedding). They are intended for mixtures of stones from natural deposits, blasted rock, quarried/processed rock, or recycled concrete. Procedures are applicable for particle sizes of 3 in. (75 mm) and above; the upper size is limited by available handling equipment. The standard provides four alternate procedures with varying levels of effort and precision and requires reports to state which procedure was used.

Key topics and requirements

• Four test procedures (A, B, C, D) to handle different sample sizes and precision: direct mass of individual particles, grouped mass ranges, measured size converted to mass, and in‑place partitioning/conversion methods for revetments.
• Applicability to natural and manufactured riprap, armor stone, filter bedding and coarse bedding materials; particle sizes ≥ 3 in. (75 mm).
• Data reporting requirements including percent finer by mass (gradation) and clear indication of the procedure used.
• Guidance on units (inch‑pound as standard with SI conversions provided for information) and conventions for significant digits and rounding (referencing Practice D6026 conventions where applicable).
• Notes on supplementary observations that can be recorded during testing (particle shape, angularity, deleterious materials, slab pieces, visual durability indicators).
• Safety and competency notices: results depend on competent personnel and suitable equipment; agencies meeting Practice D3740 criteria are recommended.

Typical use and users

Civil and geotechnical engineers, coastal and hydraulic engineers, specification writers, construction and quarry operators, testing laboratories and quality control personnel use this standard to evaluate riprap sources, accept product deliveries, assess existing revetments and produce gradation data required for design and specification of erosion protection works.

Related standards

Commonly referenced and related documents include ASTM Guide D6825 (guidance on riprap gradation and specification), Practice D3740 (competency of testing agencies), Practice D6026 (significant digits and rounding in test results), and other ASTM soil and rock standards dealing with sampling and characterization of coarse materials used in erosion protection.
