2017 “A Study on the Plastic
Waste Treatment
Methods for Road
Construction”
The experimentation atseveral institutes
indicated that the waste plastic, when added
to hot aggregatewill form a fine coat of plastic
over the aggregate and such aggregate, when
mixed with the binder is found to give higher
strength, higher resistance to water and better
performance over a period of time. Therefore,
it is proposed that we may use waste plastic in
the construction of Rural Roads
Ahmed Trimbakwala 2017 “Plastic Roads Use of
Waste Plastic in Road
Construction”
Waste plastic is ground and made into powder;
3 to 4 % plastic is mixed with the bitumen. The
durability of the roads laid out with shredded
plastic waste is much more compared with
roads with asphalt with the ordinary mix. The
use of the innovative technology not only
strengthened the road construction but also
increased the road life as well as will help to
improve the environment and also creating a
source of income.

TEST ON BITUMEN
1.PENETRATION TEST
Penetration test is used to measure the consistency of bitumen, so that they
can be classified into standard grades. Greater value of penetration indicates
softer consistency. Generally higher penetration bitumen is preferred for use in
cold climate and smaller penetration bitumen is used in hot climate areas
1. The penetration value of normal bitumen is 66mm.
2. The penetration value of bitumen with 10% plastic is 60mm.
3. The penetration value of bitumen with 15% plastic is 87mm.
The penetration value results clarify that the bitumen with 10% plastic is optimum.

2. DUCTILITY TEST
Ductility of a bituminous material is measured by the distance in
centimeters to which it will elongate before breaking when two ends of
standard briquette specimen of material are pulled apart at a specified speed
and specified temperature
Result of ductility test on Bitumen
Ductility value of normal bitumen = 83cm
Ductility value of bitumen with 10% plastic = 52cm
Ductility value of bitumen with 15% plastic = 100cm

3.VISCOSITY TEST
Viscosity denotes the fluid property of bituminous material and it is a measure
of resistence to flow . at he application temperature, this characteritic greatly
influences the strength of resulting paving mixes. low or high viscosity uring
compaction or mixing has been o0bserved to result in lower stability values.
at high viscosity , it resists the compactive effort and thereby resulting mix is
heterogeneous, hence low stability values.
Viscosity of cutback bitumen = 360seconds
Viscosity of cutback bitumen 10% plastic = 890seconds
Viscosity of cutback bitumen 15% plastic = 1000seconds
Based on the results of the viscosity test the bitumen with 15% plastic is
optimum

4. SOFTENING POINT TEST :
The softening point of bitumen or tar is the temperature at which the substance attains
particular degree of softening. As per IS: 334-1982, ASTM E28-67 or ASTM D36 or
ASTM D6493 – 11, it is the temperature in ºC at which a standard ball passes through
a sample of bitumen in a mould and falls through a height of 2.5 cm, when heated
under water or glycerine at specified conditions of test. The binder should have
sufficient fluidity before its applications in road uses.The determination of softening
point helps to know the temperature up to which a bituminous binder should be heated
for various road use applications. Softening point is determined by ring and ball
apparatus
Softening point of bitumen / tar = 53°C
Softening point of bitumen 10% of plastic = 64°C
Softening point of bitumen 15% of plastic = 40°C

5. FLASH & FIRE POINT TEST :
Flash and Fire point test is conducted on bitumen to know the safe mixing and application
temperature values of particular bitumen grade At higher temperatures bituminous materials
leave out volatiles. These volatile vapors contains hydro carbons. So, they can catch the fire
easily and will cause flash at one point and if it is further prone to heat the material may
ignite and burn

6.MARSHALL STABILITY TEST :
Marshall stability test – flow test on bitumen and is applicable to hot mix design of bitumen
and aggregates of maximum size 2.5 cm. Bituminous concrete mix is commonly designed by
Marshall Method. This test is extensively used in routine test programmes for the paving
jobs.

Preparation of Test Specimen
1. 1200 grams of aggregates blended in the desired proportions is measured and heated in the oven to
the mixing temperature.
2. Bitumen is added at the mixing temperature to produce viscosity of 170 ± centi-stokes at various
percentages.
3. The materials are mixed in a heated pan with heated mixing tools.
4. The mixture is returned to the oven and reheated to the compacting temperature (to produce
viscosity of 280±30 centi-stokes).
5. The mixture is then placed in a heated Marshall mould with a collar and base and the mixture is
spaded around the sides of the mould. A filter paper is placed under the sample and on top of the
sample.
6. The mould is placed in the Marshall compaction pedestal.
7. The material is compacted with 50 blows of the hammer (or as specified), and the sample is inverted
and compacted in the the other face with same number of blows.
8. After compaction, the mould is inverted. With collar on the bottom, the base is removed and the
sample is extracted by pushing it out the extractor.
9. The sample is allowed to stand for the few hours to cool.
10. The mass of the sample in air and when submerged is used to measure the density of specimen, so
as to allow, calculation of the void properties.

CONCLUSION :
Based on the results obtained from the comparative analysis a conclusion can be made for the strength
and durability on the bituminous roads.
As per the penetration test result values obtained,The value of the bitumen with 10% plastic is
more efficient.As per the viscosity test values obtained,The viscosity value of the bitumen sample with
15% plastic is more optimum.As per the ductility test,the value of the bitumen sample with 15%
plastic is more efficient. As per the softening point test,The values obtained from the bitumen samples
with 10% plastic is more efficient.As per the result from the flash and fire point test,The values
indicate that the bitumen sample with 10%plastic is more efficient.As per the marshall stability test
results obtained,the values of bitumen with 10%plastic and the bitumen containing 15% plastic only
have slight variation at 5.5% of bitumen content
Overall comparison of the results implies that results obtained from the bitumen sample with
10% plastic is more optimum when compared to the results obtained from the bitumen sample
containing 15% plastic.Test the penetration value :ranges between 60-70 for normal bitumen,55-60 for
bitumen with 10% plastic and 80-100 for bitumen with 15% plastic.
Marshall stability :value top for 5.5% bitumen content as a value of 17.68 for normal bitumen,22.3 for
bitumen with 10% plastic and 22 for bitumen 15% plastic.Softening point :the value of normal
bitumen is 53°C,bitumen with 10% plastic is 60°C and bitumen with 15% plastic is 43°C.Flash and
fire point test :the result value ranges between 220°C-250°C .

The ductility test: the value of normal bitumen is 83mm,the value of bitumen with 10% plastic is
52mm and the value for bitumen with 15% plastic is 100mm.Viscosity test :the value for normal
bitumen is 360seconds,for bitumen with 10% plastic is 890seconds and for bitumen with 15% plastic is
1000seconds.
Thus we conclude that adding polyethylene terephthalate(PET) plastic to the bitumen increases
the strength more than the normal bitumen with only sample,that to the sample containing 10% plastic
is more optimum for usage
