Please solve this question in step by step in hand- It is transportation-2 Civil engineering Question-4 An six-lane divided highway is to be constructed on a new alignment. Traffic volume forecasts indicate that the average annual daily traffic (AADT) during the first year of operation will be (14002), with the following vehicle mix and axle loads (single axles). Passenger cars (2000 lb/axle) = 60% 2-axle single unit trucks (8000 lb/axle) = 25% 4-axle trucks (12000 1b/axle) = 15% If the expected annual traffic growth rate is 3.5 percent for all vehicles, estimate the design ESAL, given a design period of 18 years using axle load equivalency factor (LEF) tables.
Road A is subjected to a maximum wheel load of 12000 kg and road B is subjected to a maximum wheel load of 14000 kg. The vehicle damage factor for the design of road B is 'x' times that of road A. The value of x is (Rounded upto two decimal place)
