      Key aspects that need identification when dealing with expansive soils include soil properties, suction/water conditions, temporal and spatial water content variations that may be generated, for example, by trees, and the geometry/stiffness of foundations and .   Abstract. Any pavement founded on expansive soils subgrade is often subjected to non-uniform ground movement. Such ground movement originally initiates due to variation in soil moisture within pavement subgrade, which also results in development of shrinkage cracks, edge heaves and surface : Yeasin Ahmed, Robert Evans, Monzur Alam Imteaz.

Minimization of the detrimental damage to pavements on expansive soils was the subject of a 4-yr research study conducted by the U Cited by: Essential technical information for building on expansive soils--complete with practical, proven design methods.

Expansive Soils examines factors that influence the design offoundations and pavements built on expansive soils, and exploreskey design procedures and remedial measures that address thesefactors effectively. Backed by the authors' extensive research. Expansive soils, which shrink or swell under changing moisture conditions, cause more damage to structures, particularly light buildings and pavements, than any other natural hazard, including earthquakes and floods.

This book describes the engineering problems of foundations built on expansive soils. It presents techniques for dealing with the problems of construction and.

SUBGRADE SOILS Introduction The subgrade constitutes the foundation material for the pavement structure as highway pavements ultimately rest on the native soil (subgrade). Hence the performance of the pavement is affected by the characteristics of the subgrade.

And one of the major functions of a highway pavement is to reduce the. Foundations on Expansive Soils provides the practicing engineer with a summary of the state-of-the-art of expansive soils and practical solutions based on the author's experience. The book is organized into two parts.

Part I deals with theory and practice, and summarizes some of the theoretical physical properties of expansive Edition: 1. Expansive Soils and Problems Expansive soils pose problems to civil engineers in general and to geotechnical engineers in particular (Chen ).

They cause damage to structures founded in them because of their potential to react to changes in moisture regime. They undergo severe volume changes corresponding to changes in moisture Size: KB.

Moubarak. According to Chinese Specifications for Design of Highway Subgrades, it is not appropriate to fill embankment with expansive soils, so replacing expansive soils by non-expansive materials is usually adopted, as a result serious soil erosions and damages to environments are caused frequently by highway construction in expansive soils by: 7.

variations in moisture in expansive soils and expansive soil subgrades cause damage to structures, highway pavements and other civil engineering infrastructure.
