Question

After completing his civil engineering degree, Ramesh was appointed as trainee in the R and D city development office, he was to work on the project of laying water repellent roads in the city, which one of the following method will he decide to implement for sustainability?

• A. Mixing 'Polyblend' in bitumen to be used.
• B. Adding plastic powder in the cement to be used.
• C. Mixing wax in the cement to be used.
• D. Adding cement in the mixture to be used.

Hint:

Using recycled plastic in road construction is an innovative way to reduce waste and improve the durability of roads.

Answer 1

The Correct Option is A

Step 1: Understanding the method for sustainable road construction.
Polyblend is a mixture of plastic waste with bitumen, which has been found to enhance the water repellent properties of roads. This method also helps reduce plastic waste.
Step 2: Analyzing the options.
(A) Mixing 'Polyblend' in bitumen to be used: Correct, this method is sustainable and eco-friendly.
(B) Adding plastic powder in the cement to be used: Incorrect, this method is not typically used for sustainability in road construction.
(C) Mixing wax in the cement to be used: Incorrect, while wax can be used in certain applications, it does not contribute to water resistance in roads.
(D) Adding cement in the mixture to be used: Incorrect, this is a standard practice, but not a sustainable innovation.
Step 3: Conclusion.
The correct answer is (A) Mixing 'Polyblend' in bitumen to be used, as it is a sustainable solution for water-resistant roads.
