Delhi is set to get its first plastic road, marking a major step forward in sustainable infrastructure.

• Developed by Bharat Petroleum Corporation Ltd. (BPCL) and Central Road Research Institute (CRRI).
• It involves construction technique involving 9x9x9 inch box-like cells filled with bitumen mix and plastic.

What is Geocells Technology?

• Geocells are cellular confinement systems that create a three-dimensional structure, resembling a honeycomb, when expanded. 
• They are typically made from high-density polyethylene (HDPE) or other durable polymers. 
• Geocells are designed to confine and stabilize infill materials like soil, gravel, or sand, preventing lateral movement and enhancing overall stability. 

How Geocells Work?

• Geocells are expanded on-site and filled with the chosen infill material. 
• The confinement of the infill within the cells prevents lateral spreading and movement, leading to increased load-bearing capacity. 

Applications of Geocell Technology

• Road Construction: Used to reinforce road subgrades, improving load distribution and reducing the required thickness of pavement layers. 
• Slope Stabilization: Effective in stabilizing slopes, preventing erosion, and enhancing vegetation growth on slopes. 
• Erosion Control: By confining soil and preventing its movement, geocells play a crucial role in controlling erosion on slopes, riverbanks, and coastal areas. 
• Load Support: Can be used to reinforce foundations, creating stable and durable bases for structures. 
• Other Applications: Also used in retaining walls, channel linings, and other civil engineering projects. 

Benefits of Geocell Technology

• Increased Load-Bearing Capacity: Enhance the strength and stability of the soil, allowing it to withstand heavier loads. 
• Reduced Erosion: By confining soil and preventing its movement, geocells minimize erosion and protect the environment. 
• Cost-Effectiveness: Can reduce construction costs by minimizing the need for excavation and using local infill materials. 
• Environmental Sustainability: Can be used to stabilize slopes with vegetation, promoting a more natural and environmentally friendly solution. 
• Durability and Longevity: Made from durable materials and can withstand harsh environmental conditions, ensuring long-term performance.
