It is recommended to reconstruction a new road instead old one which has a bad pavement condition. If the length of the old road is 50Km, find the length of the new road by which the project has annual benefit in vehicle operation cost (VOC) equal to 4,000,000,000 ID/year. The characteristics of the old and new pavement shown in the below table can be used for Mini bus and Trucks to find the vehicle operation costs Design hour volume (DHV)=25 Vehicle/hour, K=0.10, mini bus (10 passengers, 4 tyres )=80% Type 3 ( 2 passengers, 10 tyres )=20%. Fuel cost =500ID/ liter, oil costs =2500ID/ liter, (Tyre costs: mini bus =45000ID/ tyre, Truck = 250000ID/ tyre). Neglect the vehicle maintenance cost
