ASTM D3385-18 is a standard test method published by ASTM International. It details the procedure for measuring the infiltration rate of water through soils using a .
: This method measures infiltration rate , which cannot be used as a direct substitute for the laboratory-defined saturated hydraulic conductivity (permeability coefficient) of the soil. 3. The Double-Ring Mechanism Explained
To execute an ASTM D3385-18 compliant test, you will need a well-equipped field kit. The core apparatus components include: 1. The Rings
is the definitive international standard for field-measuring the infiltration rate of liquids into soils using a double-ring infiltrometer . Managed under the jurisdiction of ASTM Committee D18 on Soil and Rock , this active standard spans 8 pages and details the required engineering equipment, test setups, and formulaic calculations necessary to evaluate site drainage capacity. Civil engineers, hydrogeologists, and environmental scientists use the official ASTM D3385-18 Document to inform storm-water management design, agricultural irrigation layouts, and landfill liner efficiency. 1. What is the Core Purpose of ASTM D3385-18?
Water used should be similar in temperature and quality to the liquid whose infiltration is being studied. astm d338518 pdf
. The primary feature of this method is its use of two concentric rings to isolate vertical flow, providing a more accurate measurement of soil drainage and water management capacity. SCIRP Open Access Core Technical Features One-Dimensional Flow Promotion
Small plates placed inside the rings to prevent soil erosion when water is poured into the setup. 3. Ancillary Tools
Understanding how water moves through soil is critical for civil engineering, hydrology, and agricultural projects. The standard framework for measuring this movement is . This document establishes the professional protocol for using a double-ring infiltrometer to determine the in-situ infiltration rate of soils. Engineers, environmental scientists, and regulatory bodies rely on this test to collect accurate data for design and environmental compliance. What is ASTM D3385-18?
Scouring the internet for a free download may seem tempting, but consider these risks: ASTM D3385-18 is a standard test method published
Forces the water within it to flow strictly vertically. Measurements are taken exclusively from the inner ring to isolate the true, one-dimensional vertical infiltration rate. Technical Specifications and Equipment
Understanding how quickly water sinks into a land plot is essential for stormwater management, septic system designs, civil infrastructure stability, and agricultural planning. This article explores the details of the standard, its testing mechanics, equipment setups, and mathematical data processing. 1. Scope and Core Applications
. It is ideally suited for relatively uniform soils, coarse-textured soils, and materials free of large gravel or stones. The Double-Ring Principle
In geotechnical engineering, hydrology, and environmental science, understanding how water moves into soil is critical. The standard benchmark for measuring this movement in the field is ASTM D3385-18. This test method utilizes a double-ring infiltrometer to quantify the flux of water into the ground, providing essential data for construction, stormwater management, and agricultural planning. The Rings is the definitive international standard for
