Why is Bitumen Used in Road Construction?
• Bitumen gain certain unique properties that are inbuilt in it
during its manufacture.The bitumen as a raw material in flexible
road construction and bitumen as a mix (composing other
materials i.e. aggregates/ pozzolans) serves certain advantages,
that prompt to use bitumen widely in road construction.
