Why Indian engineers use water-trapping asphalt mixes?

Technical ignorance ?

Design roads to fail early – will get “fat” budget for renewal year after year ?

Lack of will power to do something for country ?

• Use readymade, open-source “KandhalMix”

• Developed by Prof. Khandal in 1980

• Shelf Life of 6 months

• “Idiot Proof” in application

• Economical

• IRC:116-2014 –“Specifications for Readymade Bituminous Pothole Patching Mix using Cut-Back Bitumen”
