Question

Who proved that blends of polyblend (plastic waste) and bitumen, when used to lay roads, enhanced the bitumen’s water repellent properties and helped to increase road life?
A) Amrita Devi
B) Ramdeo Misra
C) WH Pearsall
D) Ahmed Khan
E) Ramesh Chander Dagar

Answer 1

Hint: He is an Indian Scientist. He is also a businessman and the developer of KK Plastic Waste Management Pvt. Ltd.

Complete answer:
To answer this question, first, we need to know the uses of mixing Polyblend with bitumen which is widely used to pave highways. By adding polyblend, which is a fine plastic powder with bitumen increases the road's mechanical strength which therefore increases bitumen's temperature resistivity against very high temperatures, i.e. bitumen will not melt in places where temperature is above 45. This would prevent water from slipping into the road and thus increase road life.
Now lets us find the solution from the given options-
A) A local woman from Khejarli Village of Jodhpur District named Amrita Devi protested against the tree-felling because the Bishnoi faith prohibits such actions. The feudal party has said they will stop only if she gives them a bribe, which she declined to do because she saw it as disgraceful and an insult to her religion.
B) Ramdeo Misra is known in India for being the Father of Ecology.
C) WH Pearsall was the author who wrote The Lake District.
D) K. Ahmed Khan is an Indian scientist and also a businessman who was active in using plastic to create roads. He is the creator of KK Plastic Waste Management Pvt. Ltd. He, stung by protests to ban plastic, hit the concept of recycling plastic and mixing it with bitumen to build roads.
E) Ramesh Chander Dagar, organic farmer from the village of Akbarpur Barota, Sonipat, Haryana showed the concept behind India's most profitable farming.

Thus, the right answer is option D i.e., Ahmed Khan.

Note: Mr. Khan formed a compound known as polymerised bitumen, mixing plastic with asphalt. Mr. Khan claims that thinking of a world without plastics is impossible, but according to him recycling plastic is a better choice than banning it.
