5. a) A flexible pavement is to be designed for a highway having two lane single carriageways. The traffic survey, conducted 3 years before the completion of construction, recorded movement of commercial traffic of 265 CVPD. The VDF calculated is 2.5. The subgrade CBR is found to be 3%. Design the flexible pavement as per IRC: 37-2001 using the table as given bellow. Assume traffic growth rate as 75% per annum, and design life as 15 years.
