A national highway with dual 2 lane carriage way is to be constructed in 2017 for a design life of 25 years. However, traffic count reveals that only 2000 commercial vehicles (summation of both directions) are plying per day in year 2015 and annual rate of increase in commercial vehicle is 5%.Hence from economic reasons, it was decided to construct new flexible pavement for this in stages initially for a period of 15 years. Determine the final cumulative number of standard axles for which the highway is to be designed. (VDF = 4.8)
