ABSTRACTSoil stabilization is a process which improves the physical properties of the soil, such as increasing in shear strength, bearing capacity etc. Which can be done by the use of controlled compaction or addition of suitable mixtures like cement, lime, and waste materials like fly ash, phosphogypsum etc. The cost of introducing these additives has also increased in recent years which opened the door widely for the other kinds of soil additives such as plastic, bamboo etc. This new technique of soil stabilization can be effectively used to meet the challenges of the society to reduce the quantities of waste, producing useful stabilization from plastic waste. Use of plastic products such as polythene bags, bottles etc., is increasing day by day leading to various environmental concerns. Therefore, the disposal of plastic wastes without causing any ecological hazards has become a real challenge. Thus, using plastic as soil stabilizer is an ecological utilization since there is scarcity of good soil for construction. This project involves the study on the possible use of waste plastic.

CHAPER 1: INTRODUCTION1.1 GeneralFor any land-based structure, the foundation is very important and has to be strong
to support the entire structure. In order for the foundation to be strong, the soil around it
plays a very critical role. So, to work with soils, we need to have proper knowledge about
their properties and factors which affect their behavior. The process of soil stabilization
helps to achieve the required properties in a soil needed for the construction work.
From the beginning of construction work, the necessity of enhancing soil properties
has come to the light. Ancient civilizations of the Chinese, Romans and Incas utilized
various methods to improve soil strength etc., some of these methods were so effective that
their buildings and roads still exist.
In India, the modern era of soil stabilization began in early 1970’s, with a general
shortage of petroleum and aggregates, it became necessary for the engineers to look at
means to improve soil other than replacing the poor soil at the building site. Soil
stabilization was used but due to the use of obsolete methods and also due to the absence
of proper technique, soil stabilization lost favor. In recent times, with the increase in the
demand for infrastructure, raw materials and fuel, soil stabilization has started to take a
new shape. With the availability of better research, materials and equipment, it is emerging
as a popular and cost-effective method for soil improvement.

Here, in this project, soil stabilization has been done with the help of random plastic material obtained from waste materials. The improvement in the shear strength parameters has been stressed upon and comparative studies have been carried out using different methods of shear resistance measurement.

1.2 Why Plastic :Plastic increases the shear strength and tensile strength of soil. It can significantly enhance the properties of the soil used in the construction of road infrastructure and available abundance.
Plastic have a numerous properties that make them superior to other materials in many applications. The different types of properties are physical properties and chemical properties.
Plastic has transparency, flexibility, elasticity, water resistant, electrical resistance and soft when it is hot. Soil is a naturally occurring material?s that are used for the construction of all except the surface layers of pavements and that are subjected to classification tests to provide a general concept of their engineering characteristics.

Chemical resistance, thermal resistance, reactivity with water, flammability, heat of combustion etc., are the basic chemical properties of plastic.

1.3 Aim & Objectives :Our aim is to find the change in the property of soil, Once the plastic material is added into the soil and evaluate the optimum content of plastic at which soil gives maximum strength and to study the possible use of waste plastic to stabilize the soil economically.
Objectives :
It improves the strength of the soil, thus, increasing the soil bearing capacity.

It is more economical both in terms of cost and energy to increase the bearing. Capacity of the soil rather than going for deep foundation or raft foundation.

Sometimes soil stabilization is also used to prevent soil erosion or formation of dust.

Which is very useful especially in dry and arid weather Stabilization is also done for soil water-proofing.
It helps in reducing the soil volume change due to change in temperature or moisture content.
Stabilization improves the workability and the durability of the soil.
1.4 Types Of Stabilization Techniques :Mechanical stabilization:
Where the stability of the soil is increased by blending the available soil with imported soil or aggregate, so as to obtain a desired particle-size distribution, and by Compacting the mixture to a desired density. Compacting a soil at appropriate moisture content itself is a form of mechanical stabilization.
Chemical stabilization:
Mixing or injecting additives such as lime, cement, sodium silicate, calcium chloride, bituminous materials and resinous materials with or in the soil can increase stability of the soil. Chemical stabilization is the general term implying the use of chemicals for bringing about stabilization.
1.5 Material & Tools Required :Materials:
Plastic strips
Sieve Shaker
Stack of Sieves
Casagrande Apparatus (Liquid Limit)
Cone Penetrometer
Proctor Mold and Hammer
Weigh balance
Electronic Balance
Digital Oven with Temp. Control
Vibratory Table
Triaxail Testing Panel
CHAPTER 2: LITERATURE REVIEW2.1 General :Soils are generally stabilized to increase their strength and durability or to prevent
erosion and dust formation in soils. The main aim is the creation of a soil material or
system that will hold under the design use conditions and for the designed life of the
engineering project. The properties of soil vary a great deal at different places or in certain
cases even at one place; the success of soil stabilization depends on soil testing. Various
methods are employed to stabilize soil and the method should be verified in the lab with
the soil material before applying it on the field.

2.2 Principles of Soil Stabilization:Evaluating the soil properties of the area under consideration.
Deciding the property of soil which needs to be altered to get the design value and
choose the effective and economical method for stabilization.
Designing the Stabilized soil mix sample and testing it in the lab for intended
stability and durability values.

2.3 Soil properties :2.3.1 Atterberg Limits :1) Shrinkage Limit:
This limit is achieved when further loss of water from the soil does not reduce the
volume of the soil. It can be more accurately defined as the lowest water content at
which the soil can still be completely saturated. It is denoted by wS.
2) Plastic Limit:
This limit lies between the plastic and semi-solid state of the soil. It is determined by
rolling out a thread of the soil on a flat surface which is non-porous. It is the
minimum water content at which the soil just begins to crumble while rolling into a
thread of approximately 3mm diameter. Plastic limit is denoted by wP.
3) Liquid Limit:
It is the water content of the soil between the liquid state and plastic state of the
soil. It can be defined as the minimum water content at which the soil, though in
liquid state, shows small shearing strength against flowing. It is measured by the
Casagrande’s apparatus and is denoted by wL.

2.3.2 Particle Size Distribution :Soil at any place is composed of particles of a variety of sizes and shapes, sizes
ranging from a few microns to a few centimeters are present sometimes in the same soil
sample. The distribution of particles of different sizes determines many physical properties
of the soil such as its strength, permeability, density etc.
Particle size distribution is found out by two methods, first is sieve analysis which is
done for coarse grained soils only and the other method is sedimentation analysis used for
fine grained soil sample. Both are followed by plotting the results on a semi-log graph. The
percentage finer N as the ordinate and the particle diameter i.e. sieve size as the abscissa on
a logarithmic scale. The curve generated from the result gives us an idea of the type and
gradation of the soil. If the curve is higher up or is more towards the left, it means that the
soil has more representation from the finer particles; if it is towards the right, we can
deduce that the soil has more of the coarse grained particles.
The soil may be of two types- well graded or poorly graded (uniformly graded). Well
graded soils have particles from all the size ranges in a good amount. Sometimes the curve has a flat portion also which means there is an absence of particles of intermediate size, these soils are also known as gap graded or skip graded.
For analysis of the particle distribution, we sometimes use D10, D30, and D60 etc.
terms which represents a size in mm such that 10%, 30% and 60% of particles respectively
are finer than that size. The size of D10 also called the effective size or diameter is a very
useful data. There is a term called uniformity coefficient Cu which comes from the ratio of
D60 and D10, it gives a measure of the range of the particle size of the soil sample.
2.3.3 Specific gravity :Specific gravity of a substance denotes the number of times that substance is
heavier than water. In simpler words we can define it as the ratio between the mass of any
substance of a definite volume divided by mass of equal volume of water. In case of soils,
specific gravity is the number of times the soil solids are heavier than equal volume of
water. Different types of soil have different specific gravities, general range for specific
gravity of soils:
Sand 2.63-2.67
Silt 2.65-2.7
Clay ; Silty Clay 2.67-2.9

Soil deposits in nature exist in an extremely irregular manner producing thereby an infinite variety of combination which will affect the strength of the soil and many procedures to make it purposeful.
Soil stabilization is the process of altering some soil properties by different methods, mechanical or chemical in order to produce an improved soil material which has all the desired engineering properties. Soils are generally stabilized to increase their strength and durability or to prevent soil erosion. The properties of soil vary a great deal at different places or in certain cases even at one place the success of soil stabilization depends on soil testing. Various methods are there to stabilize soil and the method should be verified in the lab with the soil material before applying it on the field.
Dr. A. I. Dhatrak in 2015 after reviewing performance of plastic waste mixed soil as a geotechnical material. It was observed that for construction of flexible pavement to improve the sub grade soil of pavement using waste plastic bottles chips is an alternative method.

AKSHAT MALHOTRA ; HADI GHASEMAIN in 2014 studied the effect of HDPE plastic waste on the UCS of soil. In a proportion of 1.5%, 3%, 4.5% and 6% of the weight of dry soil, HDPE plastic waste was added. They concluded that the UCS of black cotton soil increased on addition of plastic waste.
CHOUDHARY JHA ; GILL in 2010 demonstrated the potential of HDPE to convert as soil reinforcement by improving engineering properties of sub grade soil.

RAJKUMAR NAGLE in 2014 performed CBR studied for improving engineering performance of sub grade soil. They mixed polyethylene, bottles, food packaging and shopping bags etc., as reinforcement within black cotton soil, yellow soil and sandy soil.

On the basis of present experimental study, the following conclusions are drawn,
Based on direct shear test on soil sample, with fiber reinforcement of 0.05%,0.15% and 0.25%, the increase in cohesion was found to be 50%, 34.6%, and 22.4%, 3.9% and 6.1% respectively. The increase in the internal angle of friction (?) was found to be 10%, 3.9% and 6.1% respectively.

Since the net increase in the value of c and ? were observed to be 100%, from 0.02kg/cm2 to 0.04kg/cm2 and 20%, from 35 to 42 degrees net increment respectively, for such soil, randomly distributed polypropylene fiber reinforcement is recommended.
The result from the UCS test for soil sample are also similar, for reinforcement of 0.05%, 0.15% and 0.25%, the increase in UCS from the initial value are 35.31%, 1.1% and 8.8% respectively. This increment is substantial and applying it for soil sample is effective.

Overall it can be concluded that fiber reinforced soil can be considered to be good ground improvement technique specially in engineering projects on weak soil where it can act as a substitute to deep/raft foundations, reducing the cost as well as energy.

Plastic such as shopping bags is used to as a reinforcement to perform the CBR studies while mixing with soil for improving engineering performance of sub grade soil. Plastic strips obtained from waste plastic were mixed randomly with the soil. A series of California Bearing Ratio (CBR) tests were carried out on randomly reinforced soil by varying percentage of plastic strips with different lengths and proportions. Results of CBR tests demonstrated that inclusion of waste plastic strips in soil with appropriate amounts improved strength and deformation behavior of sub grade soils substantially
Plastic and materials made with plastic have become the integral part of our day to day life in various stages and also in various forms, but then, the disposal and dumping of the used and unwanted plastic has become a major threat for the civilized society, as the production and usage of new plastic and plastic associated materials are not in balance with its recycling recycled plastic products status.
Plastic bottle and plastic bags recycling has not kept pace with the dramatic increase in virgin resin polyethylene Terephthalate (PET) sales and the aspect of reduce / reuse / recycle, has emerged as the one that needs to be given prominence. The general survey shows that 1500 bottles are dumped as garbage every second. PET is reported as one of the most abundant plastics in solid urban waste whose effective reuse/recycling is one of the critical issue which needs immediate attention.

From this study, we can conclude that plastic bottle strips can be used to increase the CBR value of a soil considerably. in this study we can see that the maximum CBR value can be achived when 2% amount of plastic bottle strips are added to the soil. but it decreases when further amount of plastic bottle strips is from this study,0.75% is optimum amount of the strips that can added to soil the soil for efficient use.

We can conclude from the results obtained after performing the test with plastic bag strips that 2% of the total weight of the soil is the optimum proportion of strips cutfrom plastic bags to be added to the soil for reinforcement.but it decreases when furthure amount of plastic bags strips is added.
We can also state from this study that strips cut out of plastic bottles are a better option than the strips cut out of plastic bags,as the cutting of plastic waste from bags is too laboures and time consuming ,to enhance the CBR value of the soil.

Soil stabilization in a wide sense incorporates different methods utilized for altering the properties of soil to enhance its physical properties and engineering performance.

Soil stabilization is, no doubt utilized for a range of engineering tasks, the most well known application being in the road construction and airfield pavements, where the primary goal is to build the soil quality or stability and to lessen the development cost by making best utilization of locally accessible materials.
It is important to stable the soil for any construction purpose.

In the present study, the improved CBR value of the soil is due to the addition of plastic strips.

Plastic can be utilized as one of the material that can be used as a soil stabilizing agent but the proper proportion of plastic must be there, which helps in increasing the CBR of the soil.

It can be concluded that CBR percentage goes on increasing up to 4% plastic content in the soil and thereon it decreases with increase in plastic content.

Hence, we can say that 4% plastic content is the optimum content of plastic waste in the soil.
Utilization of plastic products in various forms is enormously increasing day by day.

This has an adverse effect in nature and it is not possible to restrict its uses.

In this regard, the disposal of the plastic wastes without causing any ecological hazards has become a real challenge to the present society.
Thus, using plastic as a soil stabilizer is an economical and gainful usage because there is lack of good quality soil for various constructions.

This work serves as a means to meet the challenges of Amaravathi, the capital of newly formed Andhra Pradesh State and also to the whole society by reducing the amount of plastic waste and producing useful product from non-useful waste materials leading to the foundation of sustainable society.

The use of plastic wastes has significantly helped in ground improvement. This new technique of soil stabilization 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.

3.3 Experimental work :3.3.1 Specific gravity of the soil:The specific gravity of soil is the ratio between the weight of the soil solids and
weight of equal volume of water. It is measured by the help of a volumetric flask in a very
simple experimental setup where the volume of the soil is found out and its weight is
divided by the weight of equal volume of water.

3.3.2 ATTERBERG’S LIMITIn 1911, a Swedish agriculture engineer Atterberg mentioned that a fine grained soil can exist in four states, namely, liquid, plastic, semi – solid, solid state. The water contents at which the soil changes from one state to other are known as consistency limit or Atterberg’s limits
To determine the liquid limit of a soil
Oven Evaporating dish
425 microns IS sieve
A soil sample weighting about 150g from thoroughly mixed portion of the soil passing 425-micron IS-sieve.

Soil samples obtained shall be worked well into a paste with adding of distilled water, In the case of highly clayey soils, to ensure uniform moisture distribution, it is recommended that the soil in the mixed state is left for sufficient time (24 hours) in an air- tight container.

The wet soil paste shall then be transferred to the cylindrical cup of cone penetrometer apparatus, ensuring that no air is trapped in this process. Finally, the’ wet soil is levelled up to the top of the cup and placed on the base of the cone penetrometer apparatus.

The penetrometer shall be so adjusted that the cone point just touches the surface of the soil paste in the cup clamped in this position. This initial reading is either adjusted to zero or noted down as is shown on the graduated scale. The vertical clamp is then released allowing the cone to penetrate into the soil paste under its own weight. The penetration of the cone after 5 seconds shall be noted to the nearest millimeter.

If the difference in penetration lies between 14 and 28 mm, the test is repeated with suitable adjustments to moisture either by addition of more water or exposure of the spread paste on a glass plate for reduction in moisture content.

The test shall then be repeated at least to have four sets of values of penetration in the range of 14 to 28 mm.

The object of experiment is to determine the grain size distribution of coarse grain soil by sieving.

Balance accurate to 1 gm and 0.1 gm;
Sieves of sizes 4.76mm, 2.36 mm 1.18mm, 600 ?, 425 ?, 300 ?, 150 ?, 75 ?;
Mechanical sieve shaker
Test Procedure:
Test is performed according to IS: 2720 (part – 4) -1985.
Take a representative sample of 400 gm oven dried soil which is retained on 75 ? and passing through 4.75 IS sieves in the order of (1) 4.75 mm (2) 2.36 mm (3) 1.18 mm (4) 600 ? (5) 425 ? (6) 300 ? (7) 150 ? (8) 75 ?.
Sieve the whole assembly for 10 minutes and observe the weight retained for each sieve and find the percentage finer.
While sieving through each sieve, the sieve is agitated so that the sample rolls in irregular motion over the sieve.
The percentage of soil retained on each sieve are calculated on the basis of the total mass of soil sample taken and from this results the percentage passing through each of the sieves are calculated.
The grain size distribution curve is obtained and from that find out Coefficient of Uniformity (Cu) and coefficient of curvature (Cc).

Test procedure:
Depending on the type of mold you are using obtain a sufficient quantity of air-dried soil in large mixing pan. For the 4-inch mold take approximately 10 lbs., and for the 6-inch mold take roughly 15 lbs. pulverize the soil and run it through the # 4 sieve.

Determine the weight of the soil sample as well as the weight of the compaction mold with its base (without the collar) by using the balance and record the weights.

Measure out the water, add it to the soil, and then mix it thoroughly into the soil using the trowel until the soil gets a uniform color (See Photos B and C).

Assemble the compaction mold to the base, place some soil in the mold and compact the soil in the number of equal layers specified by the type of compaction method employed (See Photos D and E).

The number of drops of the rammer per layer is also dependent upon the type of moldS used (See Table 1). The drops should be applied at a uniform rate not exceeding around 1.5 seconds per drop, and the rammer should provide uniform coverage of the specimen surface. Try to avoid rebound of the rammer from the top of the guide sleeve.

The soil should completely fill the cylinder and the last compacted layer must extend slightly above the collar joint. If the soil is below the collar joint at the completion of the drops, the test point must be repeated. (Note: For the last layer, watch carefully, and add more soil after about 10 drops if it appears that the soil will be compacted below the collar joint.)
Carefully remove the collar and trim off the compacted soil so that it is completely even with the top of the mold using the trowel. Replace small bits of soil that may fall out during the trimming process.

Weigh the compacted soil while it’s in the mold and to the base, and record the
mass (See Photo G). Determine the wet mass of the soil by subtracting the weight of the mold and base.

Remove the soil from the mold using a mechanical extruder (See Photo H) and take soil moisture content samples from the top and bottom of the specimen (See Photo I). Fill the moisture cans with soil and determine the water content.

Place the soil specimen in the large tray and break up the soil until it appears visually as if it will pass through the # 4 sieve, add 2 percent more water based on the original sample mass, and re-mix as in step 4.

Reducing the permeability of soils.

Increasing the bearing capacity of foundation soils.

Increasing the shear strength of soils.

Improving the durability under adverse moisture and stress conditions.

Improving the natural soils for the construction of highways and airfields.

Controlling the grading of soils and aggregates in the construction of bases and sub bases of the highway and airfields.

4.2 Work To Be done in next SemesterFinding the quantity of plastic which is to be reinforced in soil for better outcome.

To compare strength of soil using bottle plastic and polythen plastic.

To perform the direct shear test by using different proportion of plastic.

To compare the results of soils without plastic and with plastic.

To optimize the size and shape of strips and increasing its percentage content.

To assess the durability and aging of the strip.

To find the possible use of plastic by which we can stabilize the soil.

4.3 FEATURES OF PROJECTThe uses of plastic are in various field but after that the waste that it becomes really has adverse effect in nature and its not easy or possible to restrict its uses but it can be used as an soil stabilizing agent which would be economical and effective implementation in engineering field.

Recently, many expensive methods for the stabilization process are carried on such as geosynthetic materials and other techniques. So, this techniques can be replaced by the reinforcement with plastic strips which will make the construction process economical and also make the proper arrangement of plastic waste conserving the various component of the environment.
