ASTM D3385-18 is the standard test method for measuring the infiltration rate of soils in the field using a double-ring infiltrometer. It is primarily used for fine-grained soils to determine how quickly water or other liquids penetrate the ground surface. Core Test Methodology
The test involves driving two open cylinders (concentric rings) into the ground and filling them with water.
Constant Head Method: Water is maintained at a fixed level in both the inner and outer rings.

The ASTM D3385-18 standard provides a rigorous procedure for measuring the infiltration rate of soils in the field using a double-ring infiltrometer. This method is essential for civil engineers, hydrologists, and environmental scientists to determine how quickly water penetrates a site's soil—a critical factor for designing drainage systems, septic fields, and irrigation networks. Overview of ASTM D3385-18
This standard, officially titled "Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer," defines the equipment and methodology required to obtain reliable field data.
Primary Goal: To measure the rate at which a liquid (typically water) enters the soil surface.
Apparatus: Two concentric rings—usually a 12-inch (300 mm) inner ring and a 24-inch (600 mm) outer ring—driven into the soil to a specific depth.
Key Application: Used for evaluating liquid waste disposal sites, septic-tank fields, irrigation requirements, and potential leakage in canals or reservoirs. Scope and Soil Applicability
The ASTM D3385-18 method is highly specialized and not suitable for all soil conditions:
Ideal Soils: Most effective for relatively uniform, fine-grained soils with moderate to low resistance to penetration.
Limitations: It may produce unreliable results in very pervious soils (hydraulic conductivity >10-2is greater than 10 to the negative 2 power cm/s) or very impervious soils ( <10-5is less than 10 to the negative 5 power
Restrictions: This test cannot be performed if the soil surface is below the groundwater table. For extremely low infiltration rates, experts often refer to ASTM D5093 (sealed inner ring method) instead. The Double-Ring Method: How It Works
The "double-ring" design is critical for accuracy because it forces water in the inner ring to flow one-dimensionally (vertically). The outer ring acts as a buffer, saturating the surrounding soil to prevent lateral (sideways) spreading from the inner measurement area. Requirement under ASTM D3385-18 Method Constant Head Method (water level is kept steady) Ring Depth Driven typically to 150 mm (6 inches) Measurement
Volume of water added to the inner ring over timed intervals Result Unit

Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer
The double-ring infiltrometer is the core apparatus. It consists of two concentric metal rings driven into the soil. Water is maintained at a constant level in both rings. The inner ring measures the vertical infiltration rate, while the outer ring creates a buffer zone to minimize lateral spread of water, ensuring that flow in the inner ring is predominantly one-dimensional (vertical).
