Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer1 astm d338518 pdf
Maintain a constant water level (usually between 50 mm and 150 mm) in both rings using Mariotte reservoirs.
The standard is particularly applicable to relatively uniform fine-grained soils, with an absence of very plastic (fat) clays and gravel-size particles, and with moderate to low resistance to ring penetration. The test surface must be cleared of loose
You can buy the ASTM D3385-18 standard directly from ASTM International through their official website ( www.astm.org ).
is where the actual measurements are taken. Because it is surrounded by the saturated buffer of the outer ring, the water from the inner ring is forced to move almost entirely downward in one-dimensional, vertical flow. Infiltration Rate of Soils in Field Using Double-Ring
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.
The test is optimized for that are free of large gravel deposits or highly plastic (fat) clays. The soil profile must present low to moderate physical resistance to ring penetration. Operational Limitations
Fill both the inner and outer rings with water simultaneously. It is critical to maintain roughly equal water levels in both rings throughout the test to prevent lateral pressure differentials.
