ROAD NETWORK IN INDIA
India has a road network of over 3.314 million kilometres of roadway.
Third largest road network in the world.As of 2008, only 49% of the network consisted of
paved roads.India plans to spend approximately US$70 Billion
by 2013 to modernize its highway network.Primary material required for road construction
are rubble, boulder, murrum, aggregate and bitumen.
PLASTIC,GROWTH RATE,EFFECTS
PLASTIC
SYNTHETIC OR SEMI-SYNTHETIC,POLYMERS OF HIGH MASS
DERIVED FROM PETROCHEMICAL IN 2010-12MILLION TONS
TILL 2015-34MILLION TONSIN INDIA ONLY
OVER 22 MILLION TONS OF PLASTICS DISCARDED EACH YEAR IN THE TRASH
60%-RECYCLE(6.5 IS RECYCLED)40%-NON-RECYCLE
PLASTIC IS NON-BIODEGRADABLE DUE TO ITS (C=C) STRONG BONDING,AFFECTS FERTILITY.
DISPOSAL BYLAND FILLS OR INCINERATION
RELEASE VERY TOXIC GASES SUCH AS CO, CO2
BITUMEN PLASTIC
Asphalt -Crude Petroleum
Residue From Distillation Of Crude Oil
Composed Of Highly Condensed Polycyclic Aromatic Hydrocarbon
Have Good Binding Property
Synthetic or Semi-synthetic
Most Plastics Are Produced From Petrochemicals
Polymers Of Ethylene, Propylene, styrene..Etc
Molten Plastic Waste Exhibits Good Binding Property.
PLASTIC AS BINDER
METHODOLOGY
AGGREGATE BITUMEN
AS PER 2386 (Part III)-1963]Sieve Analysis of Aggregate Aggregate Crushing Value
Test Los Angeles Abrasion Value
Test Aggregate Impact Value
TestSpecific Gravity TestWater Absorption Test
Penetration Test
Ductility Test
Softening Point Test
Viscosity Test
Flash and Fire Point Test
Bitumen Extractor Test
TEST ON MODIFIED AGGREGATE AND BITUMEN
RESULTS
Comparison between plain bitumen and modified bitumen (10% plastic waste):
COMPARISON
Material cost comparison for 1km road
Total material cost reduction=7.99%
EXAMPLE’sWajgaon-Kharde Road, MDR-39, Dist. Nashik
(LENGTH 146M)
plastic model was successful on major roads in Bangalore 0f about 600 km of roads1. Shankar Mutt Road, 2. K H Road, 3. M G Road (towards Trinity Circle), 4. J C Nagar Road, Miller's Road,5. Cunningham Road, 6. Rajarajeshwari Junction,
CONCLUSIONThe polymer bitumen blend is a better binder compared to
plain bitumen. Increase the durability and performance Increased Softening Point and decreased Penetration Value
with a suitable ductility. When used for road construction it can withstand higher
temperature. Hence it is suitable for tropical regions. It has decreased Penetration Value. Hence its load carrying
capacity is increased.No toxic gas is produced. Disposal of waste plastic will no longer be a problem. It is a good saving too. Hence, A better road can be constructed by using waste
plastics .
