Book Description
Modification of black cotton soils by chemical admixtures is a common method for stabilizing the swell-shrink tendency of expansive soils. Advantages of chemical stabilization are that they reduce the swell-shrink tendency of the expansive soils and also render the soils less plastic. Among the chemical stabilization methods for expansive soils, lime stabilization is most widely adopted method for improving the swell-shrink characteristics of expansive soils. Lime stabilization of clays in field is achieved by shallow mixing of lime and soil or by deep stabilization technique. Shallow stabilization involves scarifying the soil to the required depth and lime in powder or slurry form is spread and mixed with the soil using a rotovator. The use of lime as deep stabilizer has been mainly restricted to improve the engineering behaviour of soft clays Deep stabilization using lime can be divided in three main groups: lime columns, lime piles and lime slurry injection. Lime columns refer to creation of deep vertical columns of lime stabilized material. Lime piles are usually holes in the ground filled with lime. Lime slurry pressure injection, as the name suggests, involves the introduction of a lime slurry into the ground under pressure. Literature review brings out that lime stabilization of expansive clays in field is mainly performed by mixing of lime and soil up to shallow depths. The use of lime as deep stabilizer has been mainly restricted to improve the engineering behaviour of soft clays. Use of lime in deep stabilization of expansive soils however has not been given due attention. There exists a definite need to examine methods for deep stabilization of expansive soils to prevent the deeper soil layers from causing distress to the structures in response to the seasonal climatic variations. In addition, there exists a need for in-situ soil stabilization using lime in case of distressed structures founded on expansive soil deposits. The physical mixing of lime and s.

Book Description
Soil reinforcement is a very useful technique to construct several cost-effective soil structures in an environmentally friendly and sustainable manner. The most commonly used reinforcement materials are galvanised steel strips, geosynthetics in the form of woven geotextiles, geogrids and geocomposites, and fibres from natural and waste products. In recent years, there have been advances in the area of soil reinforcement, especially in the utilization of the technique in field projects. The researchers have also been working to understand the behaviour of reinforced soil considering the field challenges of reinforced soil structures. This edited volume contains contributions on advances in reinforced soil structures, mainly flexible pavements, footings, embankments, stone columns/piles, and slopes, as covered in the subject areas of geosynthetic engineering and fibre-reinforced soil engineering. The first paper by Ioannis N. Markou presents the details of sand-geotextile interaction based on interface tests with conventional and large-scale direct shear equipment. The second paper by Atef Ben Othmen and Mounir Bouassida examines the interface properties of geosynthetic reinforcement by carrying out inclined plane tests under low confinement adapted to landfill covers conditions. The third paper by J.N. Jha, S.K. Shukla, A.K. Choudhary, K.S. Gill1 and B.P. Verma deals with the triaxial compression behaviour of soil reinforced with steel and aluminium solid plates in horizontal layers. The fourth paper by M. Muthukumar and S.K. Shukla describes the swelling and shrinkage behaviour of expansive soil blended with lime and fibres. The fifth paper by S.G. Shah, A.C. Bhogayata and S.K. Shukla provides the test results of shear strength of cohesionless soil reinforced with metalized plastic waste. The sixth paper by Bouacha Nadjet compares the geotextile-reinforced and geogrid-reinforced flexible pavements based on numerical analyses. The seventh paper by S. Kumar, C.H. Solanki, J.B. Patel, P.B. Sudevan and P.M. Chaudhary reports the results of laboratory model tests carried out on a square footing resting on prestressed geotextile reinforced sand. The eighth paper by Sanoop G and Satyajit Patel presents the numerical studies on ground improvement using geosynthetic reinforced sand layer. The ninth paper by ------------------- discusses the bearing capacity prediction of inclined loaded strip footing on reinforced sand by ANN. The tenth paper by Mohamad B.D. Elsawy presents the numerical simulation of an embankment, constructed on reinforced soft soil with conventional stone piles. The eleventh paper by N.O. Sheta and R.P. Frizzi deals with the analysis, design, construction and monitoring of a geosynthetics-reinforced-earth pile-supported embankment serving as an access road. The twelfth paper by S. Banerjee, A. Adhikari, S. Chatterjee and D. Das provides the details of a case study on reinforced slope on soft soil for the approach of a major bridge. We do hope the researchers and the engineers may find the contributions in this volume very useful. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.

Book Description
This book presents mainly the geotechnical details of geomaterials (soils and rocks) found in all the 36 states and union territories of India. There are 37 chapters in this book. Chapter 1 provides an overview of geomaterials, focusing on their engineering properties as determined based on the project site investigations and laboratory/field tests; this will help readers understand the technical details explained throughout the book, with each chapter dealing with geomaterials of one state/union territory only. Each chapter, contributed by a team of authors, follows a common template with the following sections: introduction, major types of soils and rocks, properties of soils and rocks, use of soils and rocks as construction materials, foundation and other geotechnical structures, other geomaterials, natural hazards, case studies and field tests, geoenvironmental impact on soils and rocks, concluding remarks and references. All the chapters cover highly practical information and technical data for application in ground infrastructure projects, including foundations of structures (buildings, towers, tanks, machines and so on), highway, railway and airport pavements, embankments, retaining structures/walls, dams, reservoirs, canals and ponds, and landfills and tunnels. These details are also highly useful for professionals dealing with mining, oil and gas projects and agricultural and aquacultural engineering projects. Although this book covers the Indian ground characteristics, the information provided can be helpful in some suitable forms to the professionals of other countries having similar ground conditions and applications.
