Full Depth Reclamation (FDR) 

  • About: FDR is a process similar to "recycling" roads. Rather than discarding old asphalt, the technique grinds up the existing road material and mixes it with underlying soil. 
    • This mixture forms the foundation for the new road, creating a fresh, durable surface. 
  • Reinforcement: To further strengthen the base, a binder such as cement, lime, or asphalt emulsion is added.  
    • This binder acts like glue, holding the materials together and ensuring a solid foundation that can withstand heavy traffic and weather conditions. 
  • Benefits of Full Depth Reclamation: 
    • Cost-Effectiveness: The technique is economical as it reuses existing materials, reducing the need for new resources. 
    • Durability: The stabilised base layer can endure wear and tear for a long period, providing a sustainable solution to the road’s upkeep.

Bhojpur Temple

  • It is situated in Bhojpur, Raisen District, Madhya Pradesh. 
  • It was built in the 11th century by Raja Bhoj of the Paramara dynasty. 
  • It is dedicated to Lord Shiva, and included in the UNESCO World Heritage Sites tentative list in 2024.
