Abstract

As increase in the cost of land due to scarcity of good construction sites, so by increasing
engineering properties such as CBR value of weak soils such as black cotton soils. Black cotton soil is one
of the major deposits in India; this is a week soil shows high shrinkage when exposed to change in moisture
which makes this as unsuitable foundation material.
These properties can be enhanced by using geo synthetics and HDPE plastic material which are good in
tension and also acts as drainage for moisture present in soil. Changes in various properties such as CBR
value are studied. On addition of HDPE plastic by percentage weight of the soil, the increase in CBR value
is observed and an optimum value is obtained that is 2.82% which is 1.34 times higher than the unreinforced
CBR value. By altering the placement of geogrid at various depths the maximum CBR value is obtained at
H/2 of CBR mould that is 2.73% which is 2.2 times higher than the unreinforced CBR value. And
combination of both optimum conditions are also studied which gives a maximum CBR value of 3.8%
which is 3.18 times higher than unreinforced CBR value.
