effective use of wast plastic in road construction

1. What is politeness?
 Plastics are usually classified by their
chemical structure of the polymer's
backbone and side chains. Some important
 groups in these classifications are the
acrylics, polyesters, silicones,
polyurethanes, and halogenated plastics.
Plastics
 can also be classified by the chemical
process used in their synthesis, such as
condensation, polyaddition, and
crosslinking

2. Types of Plastics
. PET, polyethylene terephthalate
 HDPE, high-density polyethylene
 PVC, polyvinyl chloride
 LDPE, low-density polyethylene
 PP, polypropylene
 PS, polystyrene

3.  The people are using the plastic bags from
the market and after using they throw the
plastic bags that is called waste plastic
materials.
 i.e.- bottle , plastic bags , and other things.

4. -Utilization of waste plastic
bags and ,material.
 The waste plastic is use as binding material in the
constructing road.
 Basic intention is to efficiently utilize the waste
plastic in constructive way so that it can be beneficial
to society
 however main objectives of current project work are:
 To coat the aggregates with the waste plastic
materials
 To check the properties of bituminous mix specimen
 To check the properties of bituminous mix specimen
due to coating of waste plastic materials
 To compare the properties of bituminous mix
specimen with the properties of coated aggregates

5. The process of making
road.
 Step 1:
 Plastics waste
(bags,cups,thermocole) made out of
PE,PP and PS cut into a size between
2.36mm and 4.75mm using shredding
machine, (PVC waste should be
eliminated).

6. Cutting of plastic bags

7.  Step 2 a:
 The aggregate mix is heated to 165°c
(as per the HRS specification) and
transferred to mixing chamber.

8. Step 3:
 At the mixing chamber, the shredded
plastics waste is to be added. It get
coated uniformly over the aggregate
within 30 to 60 seconds, giving an oily
look.

9. Coating of aggrigare.

10. Coated aggregate mix with
bituminus.
Step 4:
 The plastics waste coated aggregate
is mixed with got bitumen and the
resulted mix is used for road
construction. The road laying
temperature is between 110°c to 120°c.
The roller used is 8-ton capacity.

11. Mix bituminus.

13. Characteristics of the
process
 Characteristics of the process:
 Easy process without any new machinery
 Simple process without any industry involvement
 In situ process
 Use of lesser % of bitumen and thus savings on bitumen resource
 Use of plastics waste for a safe and eco-friendly process
 Both Mini Hot Mix Pland and Central Mixing Plant can be used
 Only aggregate is polymer coated and bitumen is not modified
 Use of 60/70 and 80/90 bitumen is possible
 No evolution of any toxic gases like dioxin
 Fly ash can also be used to give a better performance
