IRC Code 26-1967: Guidelines for 200-Metre Stones in Road Infrastructure

‍

Markers like 200-metre stones are a fundamental part of road infrastructure, ensuring accurate navigation and maintenance. The IRC Code, specifically IRC: 26-1967, provides a standardized framework for designing, placing, and maintaining these stones. This blog explores the critical elements of the code and its significance in road management, emphasizing the role of these markers in India’s growing road network.

Overview of IRC: 26-1967

‍
The IRC Code outlines detailed specifications for 200-metre stones, ensuring uniformity and reliability across roads in India. These stones serve as intermediate markers between kilometre stones, assisting in accurate distance measurement and road management.

‍

Key Provisions

‍

1. Material Specificationssome text
   • The stones are constructed from locally available hard stone or reinforced cement concrete (RCC).
   • Durability and resistance to environmental wear are prioritized in material selection.
2. Placement and Installationsome text
   • Positioned on the same side as kilometre stones, at intervals of 200 metres.
   • Planted securely beyond the road edge, with the inscription facing the road centreline.
   • Fixing involves embedding the stone in materials like lime-surkhi concrete or lean cement concrete for stability.
3. Inscription Standardssome text
   • Stones are marked with ascending numerals (e.g., 2, 4, 6, 8) indicating increasing distance.
   • Numerals are black on a white background, engraved or painted for visibility.
   • This system aids in tracking distances efficiently and maintaining road organization.
4. Conversion of Existing Stonessome text
   • Furlong stones, where available, can be economically converted to 200-metre stones, maintaining resource efficiency.

Significance of the Code

‍
The IRC: 26-1967 fosters consistency and accuracy in road distance measurements. By standardizing design and placement, the code ensures that 200-metre stones remain reliable tools for navigation, road maintenance, and safety management.

‍

Conclusion

‍

The IRC Code is instrumental in creating a cohesive and efficient road infrastructure in India. The IRC: 26-1967 guidelines for 200-metre stones exemplify the importance of standardized practices for enhanced road functionality and safety. By adhering to these provisions, road authorities can ensure better distance management, contributing to smoother transportation and improved road maintenance practices.
