ASTM D3385-18 is a standard test method provided by ASTM International (formerly known as the American Society for Testing and Materials). This specific standard is titled "Standard Test Method for Permeability of Porous Concrete." The test method covers the determination of the permeability of porous concrete, which is crucial for evaluating its potential to allow water to pass through, an important characteristic for applications like pavement surfaces, parking lots, and other infrastructure projects where water drainage is a concern. astm d338518 pdf
Continue taking measurements until the infiltration rate stabilizes. A steady state is generally achieved when the infiltration rate remains relatively constant over three consecutive readings. This can take anywhere from 2 to 6+ hours depending on soil composition. Calculations and Data Analysis
The standard provides a rigorous procedure for the field measurement of soil infiltration rates using a double-ring infiltrometer. This method is essential for civil engineering and environmental projects, including the design of septic tank fields, irrigation systems, and stormwater management facilities. Understanding ASTM D3385-18
For organizations requiring regular access to ASTM standards, annual subscriptions through ASTM Compass offer cost-effective solutions with benefits including weekly updates, access to historical versions, and advanced workflow tools. Individual users can purchase single PDFs for specific projects, though they must comply with DRM restrictions and license limitations. The ASTM D3385-18 pdf standard does not cover
In conclusion, ASTM D3385-18 is a critical standard test method that provides a framework for determining the permeability of porous concrete. By understanding the importance of permeability testing and the procedures outlined in ASTM D3385-18, engineers and contractors can design and construct sustainable and durable porous concrete structures that minimize the risk of water infiltration and associated damage. As the construction industry continues to evolve, the significance of ASTM D3385-18 will only continue to grow, ensuring that porous concrete is used to its full potential in a wide range of applications.

Why it matters
The standard specifically mandates the use of a . This device consists of two concentric rings—an inner ring and an outer ring—driven into the soil.
The standard describes a field procedure using a double-ring infiltrometer—two concentric metal rings driven into the soil to measure the rate at which water moves downward through the soil profile. The infiltrometer is typically installed by driving it into the soil, though it can also be installed in a trench excavated in dry or stiff soils.
