  Module 4: Pavement Design
Lecture 28 IRC method of design of flexible pavements
  

Numerical example

Design the pavement for construction of a new bypass with the following data:
  1. Two lane carriage way
  2. Initial traffic in the year of completion of construction = 400 CVPD (sum of both directions)
  3. Traffic growth rate = 7.5 %
  4. Design life = 15 years
  5. Vehicle damage factor based on axle load survey = 2.5 standard axle per commercial vehicle
  6. Design CBR of subgrade soil = 4%.
