    The document discusses the use of waste plastics in road construction. Waste plastics are shredded and mixed with heated aggregates and bitumen. This forms a coating on the aggregates. The coated aggregates are then used in road construction and paving. Using waste plastics in this way provides benefits like increased durability, load capacity, and skid resistance of the roads compared to conventional construction. It also helps address the problem of plastic waste disposal.

     Conclusion
    Introduction
     Disposal of waste plastic is a major problem, it is non-
    biodegradable.
     Burning of these waste plastic causes pollution.

     To find is utility in bituminous mies for road construction,


    laboratory performances studies were conducted on bituminous
    mixes.
     Laboratory studies proved that waste plastic Improves the
    properties of bituminous mix.
     It is better solution for disposal in an useful way.
    What are waste plastic roads?
     The roads constructed using waste plastic, are known as Plastic
    Roads.
     Are found to perform better compared to those constructed
    with conventional bitumen.
     Plastic roads mainly use plastic carry bags, disposable cups and
    bottles that are collected from garbage dumps as an important
    ingredient of the construction material.
     When mixed with hot bitumen, plastics melt to from an oily
    over the aggrgate and the mixture is laid on the road surface
    like a normal tar road.
    Waste plastics – As Binder
     The most used plastics/ polymer materials are
    polyethlene, polystrene.
     Aroud 130-140°C they get softened without releasing
    any gaseous products.
     Various analysis has shown that there is no gas evolution
    in the temperature range of 130-180°C.
    Materials Used
     AGGREGATE:
    - Aggregate of 20mm, 10 mm.

     BITUMEN:
    - 60/70,80/100 grade bitumen.

     WASTE PLASTIC:
    - Waste plastic in the
    shredded form.
    (PVC is not Used)
    Methodology

      Construction of plastic roads


    Step 1 : Plastics waste (bags ,cups , bottles ) are cut into a
    size between 2.36mm and 4.75mm using shredding
    machine.
    Step 2 :
    (a) The aggregate mix is heated to 165°-170°C (as per the
    HRS specification) and transferred to mixing chamber.
    (b) Bitumen is heated up to 160°C (HRS Specification) to
    have good binding and to prevent weak bonding.
    (Monitoring temperature is important).
    Step 3: At the mixing chamber, the shredded plastics waste is
    added. It get coated uniformly over the aggregate within 30 to 60
    seconds, giving an oily look.
    Step 4: The plastics waste coated aggregate is mixed with
    bitumen and the resulted mix is used for road construction.
    The road laying temperature is between 110°c to 120°c.
    Advantage Of Waste Plastic Bituminous Mix

     1. More durability
     2. Improved load bearing capacity and skid resistance

     3. Plastic disposal

     4. Better resistance towards rain water and water stagnation

     5. Less wear and tear of vehicles

     6. Cost of the road will come down, as the road life is


    increased by 2 to 3 times
     7. The maintenance cost of road is very less

     8. Disposal of waste plastic will no longer be a problem.


    Conclusion:

     The waste plastic bitumen mix forms better material for


    pavement construction
     Use of waste plastics for pavement is best methods for disposal
    of waste plastics
     The use of the innovative technology strengthened the road
    construction and increases the road life as well as will help to
    improve the environment and also creating a source of income.
