Design CBR value of subgrade Initial traffic on completion of construction = 300 commercial vehicles per day, Average growth rate = 5.0 % per year, Design Life 10 years and Vehicle Damage Factor value of 2.5. For CBR value of 5% the total thickness of the pavement for different value of cumulative standard axles is given below: Cumulative standard axles (msa) 2 4 68 = Total thickness of the pavement (mm) 480 550 580 620 = 5.0%,
