⭕ A. 0.4%
⭕ B. 0.6%
⭕ C. 0.8%
⭕ D. 1%
📚 Explanation:
For aggregates used in road construction, the recommended maximum water absorption value is 0.6%.
🔹 Aggregates with **low water absorption** are preferred because they have lower porosity and higher strength.
🔹 High absorption indicates poor durability and weaker aggregate quality.
For aggregates used in road construction, the recommended maximum water absorption value is 0.6%.
🔹 Aggregates with **low water absorption** are preferred because they have lower porosity and higher strength.
🔹 High absorption indicates poor durability and weaker aggregate quality.
👉 Therefore, the correct answer is: B. 0.6%
Key Points on Aggregate Water Absorption:
- Lower absorption = better quality: Indicates dense, strong aggregate.
- IRC recommendations: Water absorption should not exceed 0.6% for road work.
- High absorption: Leads to durability issues and weak pavement performance.
