  • I'd really like to see more pictures of this particular method for soil stabilization! I don't think I've ever heard of plastic being used, unless it was used in strips. It looks like the bottles really helped with keeping the soil stable though, especially in the pictures that compared how the soil cracked. http://www.geotechsolutions.com/Rockfall_Control_Waipahu_HI.html

Plastic as a soil stabilizer

  1. 1. Presented By:- Shoaib Wani Plastic As A Soil Stabilizer
  2. 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. 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. 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. 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.
  6. 6.  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.
