IRC Code 87-2013: Manual of Specification and Standards for Six Laning of Highways Through Public Private Partnership

‍

The IRC:SP:87-2013 is a comprehensive manual published by the Indian Roads Congress (IRC) that lays down the specifications and standards for six-laning of highways under the Public Private Partnership (PPP) model. This manual serves as a crucial guideline for engineers, concessionaires, and authorities involved in highway development projects, ensuring consistency, safety, and efficiency in road infrastructure.

‍

Key Provisions of IRC:SP:87-2013

‍

1. General Planning and Applicability

• The manual is applicable for widening highways from 4-lane to 6-lane and for the construction of new 6-lane highways.
• It aligns with the Concession Agreement and is primarily designed for PPP projects but can also be used for non-PPP projects.
• It emphasizes the necessity of Quality Assurance Manuals (QAMs) before the commencement of work.

2. Geometric Design Standards

• The design speed varies based on the terrain classification:
  • Plain/Rolling terrain: 100 km/h (ruling), 80 km/h (minimum)
  • Mountainous/Steep terrain: 60 km/h (ruling), 40 km/h (minimum)
• Right of Way (ROW) should be at least 60 meters.
• Lane width is standardized at 3.5 meters per lane.
• Medians should be at least 5 meters wide in open areas and 2.5 meters in urban areas.
• Proper grade-separated structures are recommended to ensure smooth and uninterrupted traffic flow.

3. Intersections and Grade Separators

• At-grade intersections should be minimized to avoid congestion.
• Grade-separated interchanges are recommended at major junctions.
• Service roads should be continuous in built-up areas for local traffic management.

4. Pavement Design and Materials

• Pavements must be designed for a minimum service life of 15 years.
• The manual allows for both flexible (bituminous) and rigid (concrete) pavements.
• Sub-grade preparation, use of high-quality aggregate materials, and proper drainage systems are emphasized.

5. Safety and Environmental Considerations

• Crash barriers (metal beam or wire rope) should be installed along medians and road edges.
• Noise barriers are necessary near urban and residential areas.
• Provision of adequate pedestrian crossings, underpasses, and overbridges.
• Rainwater drainage systems should be integrated to prevent waterlogging.

6. Bridges and Structures

• Bridges should be designed for a 100-year flood return period.
• Expansion joints and bearings must ensure long-term durability.
• Reinforced concrete pipe culverts must be at least 1200 mm in diameter.

7. Construction, Maintenance, and Quality Assurance

• The Concessionaire must follow strict quality control measures as per IRC:SP:47 and IRC:SP:57.
• Routine and periodic maintenance of roads, bridges, and drainage systems is mandatory.
• Traffic control measures should be implemented to ensure safety during construction.

Importance of IRC:SP:87-2013 for Infrastructure Development

‍

• Helps in maintaining uniformity in road infrastructure across India.
• Enhances safety measures for vehicles and pedestrians.
• Promotes the use of advanced technology and alternative materials for sustainable road development.
• Ensures cost-effective and long-term maintenance strategies for highways.

Conclusion

‍

The IRC:SP:87-2013 is a vital document for the construction and expansion of six-lane highways in India. It sets minimum technical and safety standards, ensuring that roads meet the demands of growing traffic while maintaining sustainability and efficiency. By adhering to these specifications, road engineers and developers can enhance the quality and durability of India’s highway network, ultimately boosting the country's economic growth and connectivity.
