ASTM D3385-18 is a standard test method provided by ASTM International (formerly known as the American Society for Testing and Materials). This specific standard is titled "Standard Test Method for Permeability of Porous Concrete." The test method covers the determination of the permeability of porous concrete, which is crucial for evaluating its potential to allow water to pass through, an important characteristic for applications like pavement surfaces, parking lots, and other infrastructure projects where water drainage is a concern.
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. astm d338518 pdf
The ASTM D3385-18 standard provides a detailed methodology for determining the pore size distribution of geotextiles by the dry sieving method. This method involves passing dry soil particles of known sizes through the geotextile sample and measuring the percentage of particles that pass through. The standard outlines the equipment requirements, sample preparation procedures, and testing protocols to ensure consistency and accuracy across different laboratories and testing conditions.
