Question

Select the incorrect statement regarding polyblend.

• A. Recycled and modified form of plastic
• B. Used to lay road when mixed with bitumen
• C. Enhances the water absorbing capacity of bitumen
• D. Both A and B
  

Answer 1

Answer: (C)

Enhances the water absorbing capacity of bitumen

Polyblend is a fine powder of recycled modified plastic. The binding property of plastic makes the road last longer besides giving strength to withstand more loads when mixed with bitumen. Polyblend lowers moisture absorption capacity due to the coating of plastics at the surface.

So, the incorrect statement regarding polyblend is 'Enhances the water absorbing capacity of bitumen'.
