“…The same scenario was reported by Amadi & Okeiyi [13] in stabilizing lateritic soil with both quick lime and hydrated lime. The reason for the increased CBR for the soaked treated specimens could be the formation of cementitious chemical compounds, that are similar to the ones of portland cement such as calciumsilicate-hydrates (C-S-H), calcium-aluminate-hydrates (C-A-H) and calcium-aluminum-silicate-hydrates (C-A-S-H) associated with renewed hydration of the lime and the pozzolanic reactions [12,13]. V. CONCLUSIONS The current study investigated the effect of curing periods on the strength of sawdust-lime stabilized expansive soil samples.…”

“…The decrease in the maximum dry density for the blend consisting of 3% lime and 3% SD could be the immediate reaction of sawdust and lime with soil that is attributed by flocculation and agglomeration of the particles. On the other hand, the increase in optimum moisture content (OMC) for the sawdust-lime stabilized specimen could be the absorption of a high amount of water by lime and sawdust due to hydration [13].…”

“…Considering the trees that are cut across the globe, large quantities of sawdust are being generated [8][9]. Stabilizers increase workability, reduce the plasticity index and increase the strength of the soil [10,11,12,13]. According to Khan & Khan [14], about 10-13 % of the total volume of the wood log is processed into sawdust.…”

Subgrade strength is the main factor in determining the required thickness of any pavement. Therefore, the properties of a pavement subgrade materials must be determined, as they can predict the service life of a pavement. This paper examines the deviation of strength attained by sawdust and lime stabilized expansive soils for subgrade during different curing periods. The methodology used was conducting laboratory tests such as physical properties and mechanical property tests for both treated and untreated soil samples. In the first set-up, the soil was substituted with sawdust in the percentages of 0, 3, 5, and 7% of the dry weight of the soil, and after conducting unconfined compressive strength test, the optimum sawdust percentage obtained was 3%. The 3% sawdust was then mixed with 3% lime and 94% soil for long term tests. The sawdust-lime stabilized samples were cured for 0, 7, 14, and 28 days, and tested for unconfined compressive test and California Bearing Ratio. Based on the analysis of the results, it was concluded that a combination of 3% sawdust and 3% lime significantly improved the California Bearing Ratio and unconfined shear strength, specifically at later curing periods.

“…The reduction in MDD can be due to soil replacement by lime in the mix having comparatively less specific gravity than that of soil. The higher values of pH condition in stabilized soil has modified the distribution of surface charges in clay soil particles, leading to increased repulsion between particle layers can be another cause of MDD reduction [9].…”

Most of the rural roads are not covered by a wearing layer and sub-base is the topmost layer, hence it should be strong enough to take the load of the vehicles and not wear off due to bad weather conditions. Soil is the basic foundation of all civil engineering systems. Soil must withstand all loads without failure. In some areas, soil may be soft that cannot withstand all types of loads. Soil stabilization is required in such situations. There are different soil stabilization methods are available in the literatures. But the chemical composition of the soil is adversely affected by some approaches such as chemical stabilization. The quarry dust and lime were mixed with locally available lateritic soil to examine the improvement in the geotechnical properties in developing better subgrades for rural roads. This study presents the influence of lime, in the range of 0-5% with crusher dust blended lateritic soil. However, 4% lime addition can be observed as lime fixation point which can provide substantial increase in the workability of the soils and improved strength. Thus the properties of lateritic soil can be improved and hence locally available soil can be used as subgrade in rural road construction.

“…In order to improve the workability and mechanical behavior of loess, lime is often added to loess as mixed fill materials of loess embankments. Lime treatment is an efficient way to improve the shear strength, plasticity and mechanical behaviors of loess through a series of physical-chemical reactions, including hydration, cation exchanges and pozzolanic reaction [11][12][13][14][15][16]. When lime is added to loess, lime induces the reduction of water content through hydration and produces large amount of.…”

This paper presents a study to investigate the effects of water content, lime content and compaction energy on the compaction characteristics of lime-treated loess highway embankments. Laboratory compaction tests were conducted to determine the maximum dry density and optimum water content of loess with different lime Contents (0, 3, 5 and 8%), and to examine the effects of water content, lime content and compaction energy on the value of and . In situ compaction tests were performed to obtain the in situ dry density . The value of − achieves it's maximum value when in situ water content − was larger than the value of (+1-2%). The degree of compaction can hardly be achieved to 100% in the field construction of embankments. Higher water content and compaction energy is needed for optimum compaction.
