Test Method Title
Standard Test Method for One-Dimensional Consolidation Properties of Soils Using Controlled-Strain Loading
Reference Number
ASTM D4186
Material
Soil
Test Property
Coefficient of Consolidation
Description of Test
This test method covers the determination of the rate and magnitude of consolidation of soil when it is restrained laterally and drained axially and subjected to controlled-strain loading. Information concerning rate and magnitude of consolidation settlement of soil is essential in the design of earth and earth-supported structures. The results of this method may be used to analyze or estimate one-dimensional consolidation settlements and rates.
