The classification of the grade of shrink and expansion for the expansive soils is very important work for constructions in expansive soil area. Accurate evaluation of the estate of expansive soil may provide scientific data and basis for the prevention of engineering design and construction. This paper brings forward the classification method for expansive soil based on fractal interpolation t...

expansive soils are of the kind the volume of which will be changed to extremes by being exposed to varying conditions of moisture. this volume change is a serious menace to structures built on these types of soils. throughout the present research the potential of volume change in these soils was investigated when exposed to the phenomenon of wetting and drying. for the purpose, samples of a st...

Expansive soils swell and shrink periodically when subjected to seasonal water content changes. As a result, they are a constant source of problem in the design and construction of foundations. In this study, the behaviour of an expansive soil was studied through a number of experiments involving cycles of wetting and drying using three different water qualities. Laboratory tests were performed...

The technology of road construction is subjected to changes to cope up with changing vehicular pattern, construction materials and sub grade condition. Majority of the pavement failures could be attributed to the presence of poor sub grade conditions and expansive sub grade is one such problematic situation. Marine soils, because of the specific physico-chemical makeup are subjected to volume c...

To deal with the destructive effects of swelling soils, different methods have been proposed by researchers. Chemical stabilization of expansive soils is one of the effective methods that are low-cost and efficient economically and technically. Recently, with the improvements of nano science in nanomaterials production and application, using this type of materials has been considered in differe...

Expansive soils are one of the problematic that can cause damage to structures, such as buildings and roads. In Indonesia, geographical distribution expansive is quite widespread, in many regions including Java, Sumatera, Papua. This study was conducted by reviewing previous research on expansion degree soils. The suitability indicated activity method, Van der Merwe’s criteria, Chen’s criteria ...
