Test Method Title
Standard Method of Test for One-Dimensional Consolidation Properties of Soils
Reference Number
AASHTO T 216
Material
Soil
Test Property
Coefficient of Consolidation
Description of Test
In this test method a soil specimen is restrained laterally and loaded axially with total stress increments. Each stress increment is maintained until excess pore water pressures are completely dissipated. During the consolidation process, measurements are made of change in the specimen height and these data are used to determine the relationship between the effective stress and void ratio or strain, and the rate at which consolidation can occur by evaluating the coefficient of consolidation.
