The only way to ensure you have the complete, accurate, and up-to-date standard is to obtain it from official ASTM International sales channels. You can purchase the official PDF version from:

Driving the rings can artificially compact fine-grained soils, leading to a lower measured infiltration rate than what naturally occurs.

ASTM D3385-18 is primarily designed for soils with a high to moderate permeability profile. It yields the most accurate, reproducible results in: Granular sand Silty sand Loam and sandy loam Peat and highly organic surface soils Critical Limitations

: Designing sustainable urban drainage systems (SuDS), retention ponds, and bioswales.

Always ensure you are using the most current version or the specific version mandated by your local building code or environmental protection agency. astm d338518 pdf

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.

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 .

Measures the actual vertical infiltration rate. Because lateral flow is restricted by the outer ring's hydration barrier, the data collected from the inner ring reflects true vertical movement. Core Methodology and Equipment

The infiltration rate measured by this method has applications in liquid waste disposal studies, evaluation of potential septic-tank disposal fields, assessments of leaching and drainage efficiencies, determination of irrigation requirements, water spreading and recharge projects, and evaluation of canal or reservoir leakage, among other applications. The only way to ensure you have the

Given the natural variability of soil, the standard recommends conducting tests at multiple locations to obtain a representative infiltration rate for a given site. Test duration can vary from a few hours to several days, depending on the soil type.

The report outlines the requirements for:

For tight clays and clay-silt matrices where the infiltration rate falls below

It is particularly suited for relatively uniform fine-grained soils with low-to-moderate resistance to ring penetration. It yields the most accurate, reproducible results in:
