: The volume of liquid added to maintain a constant level in this ring is used to calculate the infiltration rate. Outer Ring : Serves as a buffer to promote one-dimensional, vertical flow directly beneath the inner ring. Infiltration Rate

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.

Record the volume of water required to maintain the constant level in the inner ring at regular time intervals.

ASTM D3385-18 standard provides a field procedure for measuring the infiltration rate astm d338518 pdf

Infiltration occurs when water at the soil surface enters the pores of the soil matrix. The rate at which this occurs is influenced by soil texture, structure, bulk density, initial moisture content, and the presence of vegetation or cracks. Initially, when soil is dry, the infiltration rate is high due to capillary suction (matric potential). As the soil saturates, gravity becomes the dominant force, and the infiltration rate stabilizes, approaching the saturated hydraulic conductivity ($K_sat$) of the soil.

: Results are calculated based on the amount of soil passing through the geotextile and are typically presented as a plot of percent passing versus particle size.
