A six lane divided highway is being designed for a current AADT of 6000 vehicles with a growth rate of 5% and a design life of 20 years. If the vehicle mix is 60% passenger cars (2 kips), 30% 3-axle single unit truck (12 kips) and 10% 3-axle tandem trailer (30 kips). The pavement has a terminal serviceability index (pt) of 2.5 and Structural Number (SN) of 5. Determine the design ESAL?
