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 50 Km, 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 Fuel consumption (L/km) Average influenced speed (km/h) 30 Tyre life (1000 km) 0.75 Oil consumption (L*1000 km) 10.5 2.0 0.3 Old pavement condition New pavement condition 80 0.15 80 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= 500 ID/liter, oil costs = 2500 ID/ liter, (Tyre costs: mini bus = 45000 ID/tyre, Truck= 250000 ID/tyre). Neglect the vehicle maintenance cost.
