In Piruzali Sadarghata area of Gazipur Sadar Upazila, 100 meters of rural roads have been made using tiles and plastic to save bitumen and brick. The local government and engineering department have said that plastic is being experimentally used to increase sustainable roads, save bitumen and increase durability. They are already expecting its positive potential.
Abdul Barek, executive engineer of Gazipur’s Local Government Engineering Department (LGED), told Jugantar that people use polythene and plastic for various purposes and leave it as waste after a while, destroying the balance of the environment. Therefore, 100 meters of rural roads have been experimentally constructed in that area to protect the balance of the environment.
Due to the adhesive properties of plastic, it has been used to mix discarded tile powders to reduce the amount of application and brickwork. As the plastic powder is mixed with the hot bitumen, the adhesive properties instantly form a new adhesive mixture. It is also likely to be useful for road durability.
The executive engineer said that the experimental road will be monitored for up to one year. This process has been taken as a pilot project. Emphasis will be placed on using the technology through further testing in the laboratory.
He also said that using this process, neighboring countries have built thousands of kilometers of highways in India. We checked. If the result is positive, it will be useful. Initially 91% bitumen is mixed with 9% plastic. In some parts of the road, instead of brick pavers, a mixture of discarded tiles has been cast. 91 kg of bitumen and 9 kg of plastic are mixed where 100 kg of bitumen was used earlier, the mixture is heated to a specified temperature. The mixture is being applied to road paving in the same manner as carpeting. The experimental process is being conducted first in Gazipur itself.
