ASTM D3385-18 establishes a standard field procedure for measuring soil infiltration rates using a double-ring infiltrometer, essential for engineering applications like waste disposal and stormwater management. It is best suited for uniform, fine-grained soils where a constant head of liquid is maintained to measure downward vertical flow. For complete technical specifications, visit ASTM International .
- Double-ring infiltrometer (inner ring: 30 cm diameter typical; outer ring: 60 cm diameter)
- Driving hammer or mallet (with a driving cap to prevent ring deformation)
- Mariotte bottle or constant-head water supply (to maintain steady water level)
- Ruler or staff gauge (precision to 0.1 cm)
- Stopwatch or timer
- Thermometer (for water temperature correction)
The ASTM D3385-18 method is highly specialized and not suitable for all soil conditions: astm d338518 pdf
One famous anecdote from the 1990s: a landfill liner design in Florida relied on lab permeability tests showing clay was nearly impermeable. But field tests using D3385 found infiltration rates 100 times higher—because natural cracks and wormholes existed. The design was changed, preventing a major groundwater contamination risk. ASTM D3385-18 establishes a standard field procedure for
