Soil deposits exist in an extremely irregular manner in
nature thereby producing an infinite variety of combination which will affect
the strength of the soil and many other soil parameter. Engineers are often
faced with the problem of constructing facilities on or with soils, regarding sufficient
strength to support the loads imposed upon them either during construction or
during the service life of the structure .Many areas of India consists of soils
with high silt contents, low strengths and poor bearing capacities .The poor
engineering performance of such soils has forced Engineers to attempt to
improve the engineering properties of poor quality soils .There are various
methods that could be used to improve the performance of poor quality soils.
The choice of a particular method depends mainly on the type of soil to be
improved, its characteristics and the type and degree of improvement desired in
a particular application. Stabilization of soils is an effective method for
improving the properties of soil and pavement system performance.
Soil stabilization is a process which improves the physical
properties of soil, such as increasing shear strength, bearing capacity etc.
which can be done by use of controlled compaction or addition of suitable
admixtures like cement, lime and waste materials like fly ash, phosphor gypsum
etc. The technique of soil stabilization using plastic can be effectively used
to meet the challenges of society, to reduce the quantities of waste, producing
useful material from non-useful waste materials.
Increased use of plastics in day to day consumer
applications has resulted in the municipal solid waste, an ever growing
fraction of plastic materials which were used for a short time and then
discarded. The linear consumption patterns of plastic bags involving single
usage and then disposal has led to environmental challenges such as diminishing
landfill space, marine and urban littering. There is, therefore a growing need
to find alternative uses of reclaimed plastic bag waste to lengthen the usage
time of the plastic material and thereby save the degrading environment. The
concept of reinforcing soil masses with strips of plastic cover may be
relatively, a new development. In contrast, the use of random-materials as
reinforcement for soil is probably not older than written history, but only
Utilizing new soil
stabilization technology, a process of cross-linking of soil and plastic can
replace traditional road/house construction methods in an environmentally friendly and effective way.
