Full textAbstract:
Expansive Black cotton clay soils are widely distributed worldwide, and are a significant damage to infrastructure and buildigs.It is a common practice around the world to stabilize black cotton soil using fly ash to improve the strength of stabilized sub- base and sub grade soil. Soil stabilization is the improvement of strength or bearing capacity of soil by controlled compaction, proportioning or addition of suitable admixtures or stabilizers. The Black cotton soils are extremely hard when dry, but lose its strength fully when in wet condition. In monsoon they guzzle water and swell and in summer they shrink on evaporation of water from there. Because of its high Swelling and shrinkage characteristics the black cotton soils has been a challenge to the highway engineers.So in this research paper fly ash has been used to improve the various strength properties of natural black cotton soil.The objective of this research paper is to improve the engineering properties of black cotton soil by adding different percentage of fly ash by the weight of soil and make it suitable for construction. A series of standard Proctor tests (for calculation of MDD and OMC) and California Bearing Ratio (C.B.R) tests are conducted on both raw Black cotton soil and mixed soil with different percentages of fly ash (5%, 10%, 20%, 30%) by weight. A comparison between properties of raw black cotton soil, black cotton soil mixed with fly ash are performed .It is found that the properties of black cotton soil mixed with fly ash are suitably enhanced.

Abstract: Black cotton soil is expansive type of soil that expands suddenly and starts swelling once it comes in contact with water. The strength of the soil is very poor due to its physical properties. Expansive soils exhibit improved response in behaviour with different types of stabilizers. Stabilization with admixtures is found to be an effective technique to improve the strength properties of the black cotton soil. During this study the potential of rice husk ash and bagasse ash are found to be useful admixtures to improve the strength properties of the expansive soil. The rice husk is an agricultural by-product from rice milling and bagasse ash is a sugarcane waste from sugar industry. In this research an approach is made to improve the properties of black cotton soil with combination of bagasse ash and rice husk ash. The results show substantial improvement in engineering properties of black cotton soil with the admixtures. Keywords: Black Cotton Soil, Rice Husk Ash, Bagasse Ash.

Abstract: The design of pavements on black cotton soil has always been a difficult task for the engineers as the structure and pavement resting on black cotton soil cracks without any warning. Black cotton soil is most commonly found in Indian region. Soil proportion changes depending upon their constituents, i.e., water content, density, bulk density, compressive strength etc. The properties of black cotton soil can be modified by stabilizing the soil with the use of additives or by mechanical means. The aim of this project is to find the optimum percentage of lime separately and lime + bamboo fibre separately to be added in black cotton Soil and study the properties of soil. In this project an attempt has been made to stabilize the soil using lime and bamboo fibre. Initially lime is blended with black cotton soil in different proportions (2%, 4%, 6%, 8%). The experimental work included the tests carried out on virgin black cotton soil and lime added black cotton soil which are Liquid limit, Plastic limit, modified proctor, specific gravity, free swell index, C.B.R. test, unconfined compressive strength test. On the basis of the soaked CBR and Modified Proctor Values, it is determined that 6% of lime is an optimum percent which can be added to stabilize black cotton soil for road construction. So, 6% lime is added with black cotton soil and different percentages of bamboo fibres (2%, 4%, 6%, 8%). California Bearing Ration, modified proctor test, Unconfined Compressive strength test are performed on the soil mixture of 6% lime + Black Cotton Soil + different percent of Bamboo Fibre. On the basis of the soaked CBR, it is concluded that if 6% lime with 8% of bamboo fibre is blended in black cotton soil, engineering properties of BCS can be improved to such an extent that the pavements built on this soil can efficiently withstand the loads applied on it while vehicular movement. Hence, according to the results obtained from experimental study, pavement design is performed for CBR 5%, 6%, 8%. The evaluation of cost for each pavement design is carried out which shows the decrease in cost of construction of pavement as the CBR values increases.

Black cotton soils are very susceptible to detrimental volumetric changes with changes in moisture. This behaviour of soil is attributed to the presence of mineral montmorillonite which has an expanding lattice. Black cotton soils because of their specific physical and chemical make are subjected to volume changes. In many countries including India, these soils are so extensive that alteration of highway routes to avoid the material is virtually impossible. Various remedial measures like soil replacement, prewetting, moisture control, lime stabilization etc. have been practiced with varied degrees of success. Extensive research is going on to find the solutions to Black cotton soils. Recent investigations on chemical stabilisation revealed that electrolytes like Calcium Sulphate, Calcium Carbonate, Zinc Chloride can be used in place of conventionally used lime, due to their ability to supply adequate cations. Fly ash is a waste by product from thermal power plants consuming thousands hectors of precious land for its disposal and also causing severe health and environmental hazards. This work presents the results of an experimental program undertaken to investigate the effect of Calcium Sulphate, Calcium Carbonate, Zinc Chloride and fly ash at different percentages on properties of black cotton soil. Atterbergs Limit of subgrade soil effect of addition of Fly Ash and Chemicals on CBR ,MDD ,OMC, From the results it is observed that 2% of Zinc Chloride and 12% of Fly ash improves the properties of black cotton soil as compared to Calcium sulphate & Calcium Carbonate. The conclusion drawn from this investigation is that a combination of 2% of chemicals and 12% of fly ash is more effective in improving the properties of black cotton soil.

The design foundation (i.e., pavements) on black cotton soil has always been a difficult task for the engineers as the structure resting on black cotton soil cracks without any warning. This research evaluates the effect of lime (anhydrous sodium sulphate) on engineering properties of black cotton soil which are considered highly problematic to civil engineering works. Black cotton soil brings about significant geotechnical and structural engineering challenges to property and infrastructure development around the world. The objective of the study is to investigate the use of lime-stabilized black cotton soil as subbase material in flexible pavements. Black cotton soil procured from the local area in Gaborone, Botswana, tested for suitability as subbase material, turned out to be unsuitable as it resulted in very less CBR value (4.8%). The black cotton soil-lime mix was checked for consistency limits, compaction, CBR for different proportions of lime (i.e., 0, 5, 10 and 15%). It was observed that the plasticity index of the soil shows a substantial decrease upon addition of the lime whereas CBR values show a marked increase with unsoaked CBR. The addition of 5%, 10% and 15% of lime produced some desirable soil properties. It can be concluded lime could be one of the best alternative stabilizer materials for highly expansive clayey.

Full textAbstract:
Various researchers, for the past few decades, had tried to stabilize black cotton soil using lime for improving its shrinkage and swelling characteristics. But these days, the cost of lime has increased resulting in increase in need for alternative and cost effective waste materials such as fly ash and rice husk ash. Brick powder, one among the alternative materials, is a fine powdered waste that contains higher proportions of silica and is found near brick kilns in rural areas. The objective of the study is to investigate the use of lime-stabilized black cotton soil and brick powder mixture as subbase material in flexible pavements. Black cotton soil procured from the local area, tested for suitability as subbase material, turned out to be unsuitable as it resulted in very less CBR value. Even lime stabilization of black cotton soil under study has not showed up the required CBR value specified for the subbase material of flexible pavement by MORTH. Hence the lime-stabilized black cotton soil is proportioned with brick powder to obtain optimum mixture that yields a better CBR value. The mixture of 20% brick powder and 80% lime-stabilized black cotton soil under study resulted in increase in the CBR value by about 135% in comparison with lime-stabilized black cotton soil. Thus it is promising to use the mixture of brick powder and lime-stabilized black cotton soil as subbase material in flexible pavements.

Full textAbstract:
To enhance the life of jute geotextiles (JGTs) for road applications, new types of JGT fabrics were developed following two different routes, viz., (a) rot-proof treatment of 100% JGT fabric and (b) preparation of jute–polypropylene blended JGT fabrics. The biodegradability behavior of these fabrics along with grey JGTs was studied for different durations up to 12 months in three categories of saturated soils, namely, Guwahati Lateritic Red soil, Kolkata Alluvial Silty soil and Andhra Pradesh Black Cotton soil and water separately. Biodegradability assessment was done through residual tensile strength study and microscopic study. The experimentation reveals that rate of biodegradation of the JGTs is different in the three experimental saturated soils and water. Saturated Black Cotton soil was found to be the most detrimental medium. Studies were also carried out to understand this differential degradation behavior of JGTs in different soils. This indicates that the pH of soil media and microbial population growing capability of the respective soils both affect the level of degradation of the JGT fabrics. Jute–synthetic blended JGT is essential for Black Cotton soil road-subgrade, while grey JGT and treated JGT can be used in Lateritic soil and Silty soil, respectively.

Abstract Expansive soils are found in black cotton soils, which swell or shrink in volume when presented to changes in moisture content. Lime treatment is exhaustively used to increment the properties of sensitive and fragile soils. One of the hugest clarifications behind using lime is to decline the developing presentation of the earth soil. The arrangement of extra safeguards improves the reaction of quicklime (CaO) with water, structures hydrated (slaked) lime (Ca (OH)2), and thus earth characteristics. The vast inadequacy of employing lime is growing the deficiency of lime offset earth. Following that, the goal of this study is to see how re-establishing time affects the geotechnical qualities of settled Black cotton soils with lime. These discoveries recommend that adding Lime as a stabilizer works on the strength of black cotton soil. Some of the characteristics of the soil likely to be increased by using stabilizer in this work are UCS (Unconfined Compressive Strength) at different curing periods (7,14,28 and 56 days), CBR (California Bearing Ratio) value at unsoaked and soaked and MDD (Maximum Dry Density) decrease at different lime percentages(%) like 2.4.6.8 and 10. The result showed here untreated soil got stabilized by using the stabilizer in certain extent In this adjustment various rates of cementitious material is added to black cotton soil and directed tests like plasticity, compaction, swell pressure, free swell index(FSI), Coefficient of permeability (k) and CBR(soaked and unsoaked) at various conditions like OMC,OMC+2% water and OMC+5% water, UCS (Unconfined Compressive Strength) was performed. From the test results, it is identified that the stabilization agent decreases plasticity and improves strength characteristics. Addition of stabilizing agent makes the black cotton soil to non-plastic, non-swelling and attains increase CBR values which are greater than 25% for a dosage of 10% lime at OMC but remaining OMC+2%water & OMC+5%water CBR values are not various much difference as per test results. With the addition of lime, the black cotton soil becomes non-plastic, non-swelling, and has high strengths. Treated soils are used as a development material, for example, a subgrade layer in the development of adaptable asphalt pavements for roads.
