Utilization of waste plastic as a binder replacement in bitumen The document discusses a study that investigated using waste plastic as a partial replacement for bitumen in road construction. The study collected and pulverized low and high-density plastic waste, then added it to bitumen in amounts up to 10% by weight. Penetration, softening point, ductility, and flash/fire point tests were conducted on the mixtures. The results showed that plastic waste increases the softening point and reduces penetration of bitumen, making it more suitable for road construction in hot weather. In conclusion, adding up to 10% plastic waste provides beneficial properties and is an effective way to reuse plastic waste.

4. Introduction
o Due to increases rate of urbanization the solid waste increases and its disposal is becoming a serious problem.
o Sources of solid waste are residential areas, business centers, hospitals, hotels etc.
o 3.5 millions tons /day solids waste is generated in world and 54,888 tons/day is generated in Pakistan(1).
o 600-700 tons/day solids waste is generated in Peshawar(2).

5. Introduction
• Plastic waste can be used as binder in bitumen which is an affective way to use plastic aggregates in road
construction.(1)
• Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine
animals, can also be affected through entanglement, direct ingestion of plastic waste.
• Plastic waste is dangerous for health because they cause serious disease of respiratory system such as (lung
cancer, chronic obstructive disease )

6. Objectives
• Sorting out of plastic waste at selected dump sites and other places.
• To investigate the possibility of adding plastic waste as a binder in bitumen.
• By conducting different tests we can compare the different properties of plastic waste containing in bitumen with
natural bitumen.

7. Problem statement
• Rapid rate of urbanization led to increase plastic generation.
• Plastic waste disposal is a major problem for municipal administration especially in urban areas.
• Plastic waste disposal has harmful effect on the environment because it is not biodegradable even with passage
of time.

9. Research methodology
• Low-density polyethylene: (LDPE)is a thermoplastic made from the monomer ethylene. It was the
first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) (1). LDPE is widely used for
manufacturing various containers, wash bottles, tubing, plastic bags for computer components and it is most
common use is in plastic bags.
• High-density polyethylene : (HDPE) is a polyethylene thermoplastic made from petroleum. It is
sometimes called "alkathene" or "polythene" when used for pipes. HDPE is used in the production of plastic
bottles, corrosion-resistant piping.(2)

10. Penetration test
• In this test we examine the consistency of a sample of bitumen by determining the distance in tenths of a
millimeter that a standard needle vertically penetrates the bitumen specimen under known conditions of loading,
time and temperature.

11. Flash and Fire test
• Flash :This test is done to determine the flash point and the fire point of asphaltic bitumen and fluxed native
asphalt, cutback bitumen and blown type bitumen. The flash point of a material is the lowest temperature at
which the application of test flame causes the vapors from the material to momentarily catch fire in the form of
a flash under specified conditions of the test.

12. Fire Point
• The fire point is the lowest temperature at which the application of test flame causes the material to ignite and
burn at least for 5 seconds under specified conditions of the test.

13. Ductility Of Bitumen
• This test is done to determine the ductility of distillation residue of cutback bitumen, blown type bitumen and
other bituminous products. The ductility of a bituminous material is measured by the distance in cm to which it
will elongate before breaking when a standard briquette specimen of the material is pulled apart at a specified
speed and a specified temperature.

14. Softening point test
• This test is done to determine the softening point of
asphaltic bitumen and road tar, coal tar pitch and blown type
bitumen as per.
• IS 1205 – 1978.
