You have been asked to design a flexible pavement and the following daily traffic is expected for design: 6375 passenger cars with two 2-kip single axles, 375 18-wheel trucks with one 12-kip single axle and two 32-kip tandem axles, 225 triple-trailer trucks with one 18-kip single axle and six 36-kip tandem axles, and 525 single unit trucks with one 10-kip single axle and one 24-kip tandem axle. There are 3 lanes in the design direction (conservative design is to be used). Assuming a structural number of 5.0, determine the design-lane 18-kip ESALs for the pavement projected 15-year design life with the TSI of 2.5
