ASTM D3385-18 establishes a field procedure using a double-ring infiltrometer to measure the liquid infiltration rate of soils. This constant-head method helps determine vertical soil permeability for environmental and engineering projects by recording water volume over time. For more details, visit ASTM . Standard ASTM D3385-18 - Afnor EDITIONS

: The standard requires two open cylinders, typically with diameters of 300 mm (inner) and 600 mm (outer) and a height of approximately 500 mm. Constant Head Method

Fabricated from smooth, rigid metal (such as steel or heavy-gauge aluminum). Inner Ring: Typically 300 mm (12 inches) in diameter. Outer Ring: Typically 600 mm (24 inches) in diameter. astm d338518 pdf

Gently tamp the soil along the inside and outside edges of both ring walls to eliminate any artificial voids or paths created during driving. Place a thin layer of fine sand or a splash guard cloth inside the inner ring to prevent the incoming water from eroding or scouring the soil surface. Step 4: Adding Water and Maintaining Head

Identify a representative test location free of surface debris, large roots, and heavy vegetation. ASTM D3385-18 establishes a field procedure using a

Clear loose debris, vegetation, and rocks from the surface. Avoid scraping or compacting the target test zone. Step 2: Driving the Rings Center the inner ring inside the outer ring.

Select a flat, undisturbed area. Gently clear away loose surface debris, heavy vegetation, and thatch. Avoid excavating or scraping deeply, as this alters the natural bulk density and structural porosity of the topsoil layer. Step 2: Driving the Rings

Civil engineering projects require strict adherence to code standards. Citing the official ASTM document protects projects from liabilities and ensures approval from municipal building departments and environmental protection agencies.
