Test Method Title
Standard Test Method for Permeability of Granular Soils (Constant Head)
Reference Number
ASTM D2434
Material
Soil
Test Property
Coefficient of Permeability
Description of Test
This test method covers the determination of the coefficient of permeability by a constant-head method for the laminar flow of water through granular soils. The procedure is to establish representative values of the coefficient of permeability of granular soils that may occur in natural deposits as placed in embankments, or when used as base courses under pavements. In order to limit consolidation influences during testing, this procedure is limited to disturbed granular soils containing not more than 10% soil passing the 75-µm (#200 sieve).
Number of Test Specimens
