OBJECTIVESOBJECTIVES

Optimization of bitumen content by addition of plastics.

Comparison of bitumen mix characteristics before & after the addition of plastics.

Study the benefits of using plastics as an additive.

INTRODUCTIONINTRODUCTION

WASTE PLASTICS-AS BINDER AND MODIFIER:-

Waste plastics on heating soften at around 130°C.

The softened plastics have a binding property. Hence, the molten plastics materials can be used as a binder and/or they can be mixed with binder like bitumen to enhance their binding property.

This may serve as a good modifier for the bitumen, used for

road construction.

NEED FOR THE PROJECTNEED FOR THE PROJECT

Plastic is non-biodegradable.

Disposal of waste plastic is a major problem.

Burning of waste plastic causes environmental pollution.

Plastic block drains and cause flooding in cities.

Waste plastic can be used as a binder in bituminous road

construction when it is melted.

A better and economic road with the use of waste plastic.

CONCEPTCONCEPT

The Concept of Utilization of Waste Plastic in Bituminous Mixes for Road Construction has been done since 1997 in India.

One such technology is called Bangalore’s KK process.

Bangalore-based firm, K K Poly-flex and a team of chemical engineers from RV College of Engineering, Bangalore, have developed a way of using plastic waste for road construction

KK PROCESSKK PROCESS An initial study was conducted in 1997 by the team to test

for strength and durability and further research was done by transportation Dept of Bangalore university.

In practice, such a “plastic road” laid in Bangalore (at the Rajarajeshwari Junction) in March 2001.

Showed superior smoothness and uniformity and less rutting.

The process was also approved in 2003 by the Central Road Research Institute, Delhi.

This process got patent from Govt of India.

COLLECTION OF WASTE PLASTICCOLLECTION OF WASTE PLASTIC

Collected from roads, garbage trucks, compost plants and by purchase from rag-pickers.

CLEANING AND SHREDDING CLEANING AND SHREDDING

CLEANING PROCESS

waste plastic are sorted,

de-dusted, cleaned if

necessary.

SHREDDING PROCESS

cleaned plastic is cut into

smaller size using

shredding machine.

MIXING OF WASTE PLASTIC, AGGREGATE AND BITUMEN IN CENTRAL MIXING PLANT:-

The aggregate mix is heated to 1650c (as per the HRS specification) in central mixing plant.

Similarly 4.6%of bitumen to the weight of mix is to be heated up to 160ºc separately.

The 8% of waste plastic to the weight of bitumen are added in the conveyor belt &heated bitumen is also sprayed

LAYING OF BITUMINOUS MIXLAYING OF BITUMINOUS MIX

The road laying temperature is between 1100c to 1200c. The roller used is 8-ton capacity.

The Bruhat Bengaluru Mahanagara Palike (BBMP) has used plastic on about 600 km of roads, including arterial roads.

The plastic model was successful on major roads in Bangalore, including Shankar Mutt Road, K H Road and other roads shown below.

SOME OTHER ROAD CONSTRUCTIONS….. The Engg. Dept. of the administration has constructed the

carriageway of 1.2 km out of a total length of 2.4 km for slow moving traffic in Sector 27 in CHANDIGARH using 5% waste plastic with bitumen.

Field trials have also been carried out, using Dry process in DELHI under which about 3.5km road stretch has recently been constructed with 40mm bituminous concrete overlay on the above said location. The section will be monitored for another three years for its performance

The Himachal Pradesh State Pollution Control Board in collaboration with the Public Works Department (PWD) has built three road stretches on a pilot basis by using shredded plastic waste on the outskirts of SHIMLA.

A trial was organized for mixing of Plastics Waste with stones and bitumen in MCGM’s high speed Central Mixing Plant at WORLI and to use the mixed aggregate for the construction/ repair work of Tar Road.
