The following data pertains to the number of commercial vehicles per day for the design of a flexible pavement for a national highway as per IRC:37–1984
Assuming a traffic growth factor of 7.5% per annum for both the types of vehicles, the cumulative number of standard axle load repetitions (in million) for a design life of ten years is
-
- 44.6
- 57.8
- 62.4
- 78.7
Correct Option: B
Cumulative standard axle:
(1) 2 axle truck :
= 51.6 msa
(2) Tandem axle truck:
= 6.2 msa
Total CSA = 51.6 + 6.2 = 57.8 msa
