The highest CBR number is required for __________a)Pavementb)Sub grade...
Sub grade requires the highest CBR number
Explanation:
- Definition of CBR: CBR stands for California Bearing Ratio, which is a penetration test to evaluate the strength of subgrade soil and other materials.
- Importance of CBR: CBR is crucial in determining the load-bearing capacity of different layers in a pavement structure.
- CBR requirements for different layers:
- Subgrade: The subgrade is the native soil underneath the pavement layers. It requires the highest CBR number as it directly supports the pavement structure and needs to withstand the applied loads.
- Sub base and base: While sub base and base layers also require good CBR values, they are primarily responsible for providing a stable foundation for the pavement layers above.
- Role of CBR in sub grade: A high CBR value in the subgrade ensures that it can resist deformation and provide adequate support to prevent premature pavement failure.
- Consequences of inadequate CBR in sub grade: If the subgrade has a low CBR number, it can lead to settlement, rutting, and structural distress in the pavement layers above.
- Conclusion: In conclusion, the highest CBR number is required for the subgrade to ensure the long-term performance and durability of the pavement structure.
