Astm D338518 Pdf Online

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.

2. Literature Review

• Conduct a literature review to find existing research on the permeability of porous concrete. This can help you understand the background, significance, and applications of the standard.

2.2 The Principle of Lateral Flow Containment

A primary challenge in field infiltration testing is the divergence of flow lines. In a single-ring infiltrometer, water infiltrates vertically but also spreads laterally due to capillary forces and the geometry of the wetting front. This lateral spreading artificially inflates the measured infiltration rate because the wetted area increases with depth. astm d338518 pdf

Challenges and Limitations

While ASTM D3385-18 provides a valuable tool for evaluating geotextiles, there are challenges and limitations, including variability in testing results and the influence of test conditions on the measured pore size distribution. Additionally, field performance can sometimes differ from laboratory results due to installation conditions, soil properties, and long-term degradation.
