“…Wang et al [ 18 ] presented a semi-analytical method to analyze the creep and thermal consolidation behaviors of layered saturated clays due to surface loads. Wong et al [ 19 ] proposed a methodology to decouple the creep-deformation component from the total deformation measured in oedometer tests, which can determine the intrinsic properties of a 1D normally consolidated curve and creep behavior. Wang et al [ 20 ] proved that the constitutive model of backfill consolidation and creep can be used to describe the creep behavior of the backfill under the high stress conditions of confinement.…”

Frost heaving and boiling are the most common road disorders due to the special climatic conditions in a seasonal frozen area. From the perspective of controlling road disorders in seasonally frozen areas and making effective use of industrial waste residue, two kinds of subgrade modified soil—crumb rubber modified fly ash soil (CRFS) and oil shale waste residue modified fly ash soil (OSFS)—were proposed by the research group. The research results proved that the two new subgrade fillers both have excellent engineering characteristics in cold areas, such as high strength and low thermal conductivity, and both have the function of waste utilization, giving them broad application prospects. In road engineering, the instability of slopes and retaining walls and the uneven settlement of the subgrade are closely related to soil creep, which are problems that cannot be ignored in road design and use. As a new material to treat road disorders in seasonally frozen areas, more attention should be paid to the continuous deformation property of modified soil under long-term load. The study on the creep characteristics of the modified soil can provide reliable parameters for the design of the modified soil subgrade and predict the settlement of the subgrade after construction, which is of great significance to the stability of the subgrade. In this paper, an experimental study on the consolidation–creep characteristics of two kinds of subgrade modified soil in a seasonal frozen region was carried out, the relationship between modified soil deformation and time is discussed, and the effects of different moisture contents and compaction degrees on the creep characteristics of modified soil were analyzed. The test results provide parameters for the engineering design of modified soil subgrade and provide data support for the popularization and application of modified soil in seasonally frozen subgrade.

“…It possesses higher strength in the dry condition which reduces significantly in the saturated condition [6]. It undergoes settlement under the application of constant load and undergoes swelling during reloading in the saturated condition [7]. Because of inconsistent strength and volume, highly cracking nature, it leads to severe damages to buildings and foundations.…”

The clayey soil containing montmorillonite minerals exhibits both time-dependent compression called creep and swelling behavior, which is time-dependent expansion. Both the creep and swelling characteristics of the clayey soils have a significant influence on the deformation and failure of geotechnical structures. Study of time-dependent stress-strain behavior of a clayey soil is a great concern for construction purposes. In this paper, the long-term time-dependent behavior of Indian Black Cotton (BC) soil is investigated under a series of test in Oedometer apparatus at different loading pattern. The experimental result shows that non-linear function is suitable for prediction of long-term creep and swelling behavior of BC soil. Using the non-linear function, the behavior of the strain rate with time and the effective stress is studied. The strain rate, after the end of primary consolidation, decreases non-linearly to attain an equilibrium after reaching an equilibrium condition, and it is independent of the loading. The experimental result indicates that BC soil shows the repeated ability to swell at different stages of loading-reloading cycles. The experimental results along with the performance evaluation of the analytical model to predict long-term consolidation and creep behavior of BC soil are presented and discussed in details.
