Overview of IRC:28-1967

‍
The IRC:28-1967 provides a practical framework for stabilizing soil roads, particularly focusing on regions with high rainfall. It introduces specifications to optimize road construction, ensuring durability and safety for varying traffic loads.

‍

Key Provisions

‍

1. Scope and Applicabilitysome text
   • Designed for areas with moderate to high rainfall (up to 150 cm annually).
   • Applicable for low to high traffic conditions, including mixed traffic loads ranging from 50 to 500 tons per day.
2. Base and Wearing Course Requirementssome text
   • The base course uses soil with controlled plasticity and a high sand content, compacted with heavy rollers for structural stability.
   • The wearing course involves a blend of soil and soft aggregates like brick aggregates, moorum, or kankar for additional strength.
3. Surface Treatment for Enhanced Durabilitysome text
   • For roads supporting higher traffic, surface dressing is essential.
   • Treatments involve applying bituminous primers or premix carpets as per other IRC standards (e.g., IRC:23).
4. Stabilization Techniquessome text
   • Encourages using local materials like laterite and soft aggregates to minimize construction costs.
   • Recommends specific grading and compaction methods to optimize strength and resistance to weather effects.
