The predicted traffic mix of a proposed four-lane urban non-interstate freeway: Passenger cars (4.44kN/axle) = 65% 2-axle single unit trucks (22.2kN/axle) = 24% 2-axle single unit trucks (40kN/axle) = 6% 3-axle or more single-unit trucks (100kN/axle) = 3% 3-axle or tractor semitrailers and combinations (90kN/axle) = 2% The projected AADT during the first year of operation is 4000 (in both directions). If the traffic growth rate is estimated at 4%, the percent of the traffic on the design lane is 43%, p =2.5, and SN =3, calculate the design ESAL at the design life of 25 years.
