Permanent Deformation of Subgrade Soils
Few research projects have been conducted on the permanent deformation of subgrade soils in China. Based on a comprehensive literature review, a testing procedure to evaluate permanent deformation in subgrade soils is developed and presented in this paper. The parameters in the permanent deformation test include confining pressure, deviator stress, load shape, load duration, load rest period, moisture content and dry density. Using the procedure, the authors conducted repeated load tests for three subgrade soils. The test results are in good agreement with the relationships between the permanent strain and the number of load applications proposed by Tseng and Lytton. The regression models for sand, silty clay and clay have been developed from these results.
