The 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

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 astm d338518 pdf

Usually 24 inches (600 mm) in diameter. It acts as a buffer to limit the lateral spread of water, ensuring that water from the inner ring moves in a one-dimensional, vertical flow for more accurate results. Test Procedure and Methodology The standard provides a rigorous procedure for measuring
