Which of the following code is used for the design of flexible pavement in India?
- AIRC 115
- BIRC 37:2018Correct
- CIRC 58:2015
- DIRC SP:76-2015
Solution
Concept
Flexible Pavement Design
Formula
No
Step-by-step solution
This is a direct conceptual/factual question; IRC 37:2018 is the standard guidelines code published by IRC for flexible pavement design. No calculation is required.
Explanation
IRC 37:2018 is the official guideline published by the Indian Roads Congress (IRC) that provides the standard specifications and design procedures for flexible (bituminous) pavements in India.
Shortcut
Remember: "Flexible at 37, Rigid at 58" (IRC 37 for Flexible pavement, IRC 58 for Rigid pavement).
Common mistake
Many students confuse IRC 37 (used for flexible pavements) with IRC 58 (used for rigid pavements) and mistakenly select Option C.
Correct answer: B) IRC 37:2018
