Book Description
Peat and organic soils commonly occur as extremely soft, wet, unconsolidated surficial deposits that are an integral part of wetland systems. These types of soils can give rise to geotechnical problems in the area of sampling, settlement, stability, in situ testing, stabilisation and construction. There is therefore a tendency to either avoid building on these soils, or, when this is not possible, to simply remove or replace soils, which in some instances can lead to possibly uneconomical design and construction alternatives. However, in many countries of the world, these soils cover a substantial land area and pressure on land use is resulting in ever more frequent utilisation of such marginal grounds. For the successful design, construction and performance of structures on such marginal soils, it is crucial to predict geotechnical behaviour in terms of settlement, shear strength and stability, with respect to time. This means expanding our knowledge base and calls for a reliable characterisation of their geotechnical properties and mechanical behaviour and subsequently, the devising of suitable design parameters and construction techniques for dealing with these materials. A sound scientific understanding of the nature and functions of peat and organic soils is critical to their correct and safe use, and this book contributes by offering students, researchers, engineers and academics involved with these types of soils a comprehensive overview. This book will be useful not only to those in the field of geotechnical engineering, but also to soil scientists and agriculturalists, who are involved in the development of peatlands.

Book Description
Construction of roads on peat soil has always been a challenge to the engineers. This study was carried out to establish cost effective pavement design on peat soil and the design is considered for low volume roads. For this purpose, the study was mainly concentrated on shallow depth of peat soil of up to 6m. The minimum CBR value of 0.5 which corresponds to a Roadbed Resilient Modulus of 5.20 MN/m2 has been assumed and adopted for the organic/peat soil. Two options were explored and compared for their pavement thickness and cost effectiveness. Option 1 method adopts the conventional way of removal and replacement of the soft material entirely. This method is quite common in our country but the limitation is the availability of suitable fill as well as environmentally acceptable location for dumping ground within an economically acceptable haul distance. Meanwhile Option 2 adopts low embankment height with geotextile and geogrid reinforcement as an alternative to Option 1, where no removal or replacement is considered. The study concluded that, Option 2 is much more economical as compared to Option 1 which is about 3.5 times more expensive. The consolidation settlement is not really that excessive, whereby for the first five years and ten years the settlement is about 255mm and 355mm respectively. This proves that if the settlement is controlled to be uniform throughout the road section with the help of geogrid reinforcement, the pavement will be in tact and may last for the intended design life period.

Book Description
Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.
