It is proposed to widenand strengthen an existing 2lane NH section as a dividedhighway. The existing traffic inone direction is 2500 commercialvehicles (CV) per day. Theconstruction will take 1 year. Thedesign CBR of soil subgrade isfound to be 4 percent. Given:traffic growth rate for CV = 8percent - vehicle damage factor =3.5 (standard axles per CV) - design life = 10 years and trafficdistribution factor = 0.75. Thecumulative standard axles (msa)computed are
