Plastic As A Soil Stabilizer

2. Introduction:
 Soil stabilisation means the improvement of stability or bearing capacity
of the soil by the use of controlled compaction, proportioning and/or the
addition of suitable admixture or stabilisers.
 The objective of this study is to improve the characteristics at site and
make soil capable of carrying load and to increase the shear strength by
decrease the compressibility of the soil.

3.  Soil stabilisation using raw plastic bottles is an alternative method for the
improvement of sub grade soil of pavement.
 It can significantly enhance the properties of the soil used in the
construction of road infrastructure. Results include a better and longer
lasting road with increased loading capacity and reduced soil permeability.

4.  In order to conduct this study, various materials such as lateritic soil,
plastic bottles (both cut and uncut), sea sand and synthetic threads were
used.
 The Standard Proctor Compaction tests were done to assess the amount of
compaction
 The California Bearing Ratio test was conducted to determine the optimum
amount of plastic strips in soil. This is done by mixing soil with varying
percentages (0.0%, 0.2%, 0.4% etc.) of plastic strips in soil and the 4 day
soaked CBR Value is obtained
 Plate load tests were conducted with plain lateritic soil

5. RESULTS AND DISCUSSIONS
COMPACTION TEST:-From the compaction curve, the maximum dry
density and optimum moisture content were obtained as 18.95kN/m3 and
11.22 % respectively.

11.  The use of plastic wastes has significantly helped in ground improvement.
 This new technique of soil stabilisation can be effectively used to meet the
challenges of society, producing useful material from non-useful waste
materials.
 It can significantly enhance the properties of the soil used in the
construction of road infrastructure. Results include a better and longer
lasting road with increased loading capacity.
