Infrastructure & Sustainable Development

What is Reclaimed Asphalt Pavement (RAP) and how does bitumen rejuvenation function in green road construction?

  • RAP Definition: Recycled materials recovered from milling old asphalt pavements during road widening or maintenance projects.
  • Rejuvenator Role: Chemical additives (rejuvenators) that restore the rheological and mechanical properties of aged, oxidized bitumen to match virgin binders.
  • Environmental Benefits: Massively cuts virgin aggregate extraction, reduces petroleum-based bitumen demand, and lowers carbon emissions in highway construction.

আন্তঃবিষয় প্যাটার্ন

  • Infrastructure Decarbonization + Circular Economy Principles

    High-RAP road technology directly operationalizes circular economy principles by turning decaying national highways into resource banks for future infrastructure.

  • Atmanirbhar Bharat + Indigenous R&D in Roads

    Indigenous rejuvenators like REJUBIT illustrate how public-private R&D partnerships between CSIR labs and MSMEs drive self-reliance in strategic infrastructure.

High-RAP road tech and indigenous rejuvenators (like REJUBIT) will likely be tested via a multi-statement question on green infrastructure.
