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.

Preferred Test Sample Size

2.87 in diameter x 3 ft Shelby tube or equivalent

Number of Test Specimens

1

Test Specimen Size

2.5 in diameter x 1 in in height

Keywords

Compressibility, compressibility coefficient, CRS, consolidation coefficient, consolidation test, consolidometer, pre-consolidation stress, settlement
