It is proposed to widen and strengthen the existing 2-lane NH section as a divided highway. The existing traffic in one direction is 2500 commercial vehicles (CV) per day. The construction will take 1 year. The design CBR of soil subgrade is found tobe 5 per cent. Given : traffic growth rate for CV = 8 per cent, vehicle damage factor =3.5 (standard axles per CV), design life = 10 years and traffic distribution factor =0.75. Calculate the cumulative standard axles.

Question
(i) It is proposed to widen and strengthen the existing 2-lane NH section as a divided
highway. The existing traffic in one direction is 2500 commercial vehicles (CV) per
day. The construction will take 1 year. The design CBR of soil subgrade is found tobe 5 per cent. Given : traffic growth rate for CV = 8 per cent, vehicle damage factor
=3.5 (standard axles per CV), design life = 10 years and traffic distribution factor
=0.75. Calculate the cumulative standard axles.
