4.9. Code Recommendations and Standards

Try these first

1. 1.

   What does IRC:37 address?

   Hint

   Think about the relation with flexible pavement types.

2. 2.

   What does MORTH refer to?

   Hint

   Remember it’s related to maintenance and standards.

3. 3.

   What does IRC:37 primarily focus on?

   • Rigid pavements
   • Flexible pavements
   • Soil testing

   Hint

   Consider the material types when thinking about this.

4. 4.

   True or False: AASHTO T 307 tests soils for their resilient modulus.

   • True
   • False

   Hint

   Think about elastic behavior under load.

5. 5.

   Design a flexible pavement for a new road considering the specified CBR value. Discuss how IRC:37 affects your design choices.

   Hint

   Refer to the relationship between CBR values and layer thickness.

6. 6.

   Critique the importance of time-tested standards like IRC:58 in modern road construction, focusing on technological advancements.

   Hint

   Consider how technology adapts or complements existing standards.
