Green road is constructed by using certain a certain percentage of shredded plastic in the traditional road paving process, no extra machinery or process required.
Benefits of Green Road:
- The cost in laying road will reduce as there will be lesser quantity of bitumen used.
- This is a very simple technology which does not involve any special machines deployment or other advanced skilled professionals.
- Improve spot use of the waste plastic.
- These water proof roads provide considerably increased durability.
- No stripping of roads happens as this kind of roads resist the permeation of water.
- This innovation provides road with double strength, thus increasing higher load ‐ carrying capacity.
- No maintenance will be required for years as the surface remains without any cracking or potholes.
- As part of this process, women can be empowered through employment in Self Help Groups.
- More employment can be generated as labours will be required in collection, segregation and shredding of waste plastics.
- Multi‐layer films can be used which provide strength and durability.
- No new machinery required so any additional infrastructure or cost is not required for this technology implementation.
- No industry involvement or expert consultancy is required which could add cost (except quality control and monitoring).
- No granulation or powdering of plastics‐ only shredding is required.
Learn why plastics are the most useful resources for road construction:
Plastics are the inventions that have paved a road for the rapid technological advancement and exponential development in the world but it is paving a huge potential threat to the future of mankind. While plastic is one of the greatest discoveries of the 20th century, the management of these non-biodegradable materials is a huge problem whose solution is not being reflected upon. This is a multidimensional problem but the major change needs to happen in the mindset of humans who have the power to challenge the existing system. The benefits of paving Green Roads can be simply put like this:
It addresses the non-biodegradability of plastics and basically helps in lengthening the life-span of plastic materials which would either end up being dumped in the landfills or in the ocean posing a threat to bio-diversity of planet. Some of the major day-to-day problems from plastics are choking of drains, promotion of stagnation of water which can be a breeding ground for many vectors carrying diseases and release of toxic gases upon incineration.
Apart from improving the quality and lifetime of roads, green roads shall benefit waste management, road construction and maintenance and public health to an astonishing degree.
Plastic‐tar roads have benefits over conventional roads such as the overall reduction in bitumen consumption by 8%, enhanced load carrying strength, reduced wear and tear, prevents release of 3 tonnes of CO2 (compared to disposal by burning) into the atmosphere, increased road strength, excellent resistance to water and water stagnation, no stripping and potholes formation, enhanced binding, reduced rutting and ravelling, improved soundness property, negligible maintenance cost of the road, no leaching of plastics and no effect of UV radiation. Waste plastic that can be used include cups, carry bags, polythene and polypropylene foams and thermocol.
The main problems in the construction are determination of plastic hotspots which would allow clean plastic sourcing as raw materials for the road which would ease supply constraints. That is why Green Roads is working on the Waste Audit sector so that a good end-of-life value can be provided for the wastes if properly segregated. Lack of consistent demand and trust for the companies who pave plastic roads is also a challenge for now.
Plastics are thus, a boon to humanity and improper management is paving roads to a human built catastrophe due to the same plastic. Utilization of plastics in roads don’t just utilize plastic but improves important properties like water resistance of roads with additional financial benefits by saving costs on the whole road construction process. Thus, plastic road construction can be considered as a way to manage those wastes which would rather have gone to landfills to never decay or made their way to the oceans to affect marine biodiversity.
