ASTM D3385-18 outlines the field procedure for measuring soil infiltration rates using a double-ring infiltrometer to evaluate liquid penetration, particularly for engineering and environmental applications. This standard test method maintains a constant hydraulic head in concentric rings to measure one-dimensional vertical flow in relatively uniform, fine-grained soils.

This paper provides an in-depth examination of ASTM D3385-18, the standard test method designated for determining the infiltration rate of soils in the field using a double-ring infiltrometer. As water infiltration is a critical parameter in geotechnical engineering, hydrology, agriculture, and environmental remediation, the accuracy of field data is paramount. This document explores the theoretical underpinnings of the double-ring method, details the apparatus and procedural requirements set forth by the ASTM standard, discusses the calculation of infiltration rates, and analyzes the sources of error and limitations inherent in the methodology. Furthermore, this paper addresses the significance of the 2018 revision in the context of modern engineering practices and compares the method with alternative infiltration measurement techniques.
