A flexible pavement (SN = 4) is to be designed to last 10 years. The daily car traffic is 28,753, and the daily truck traffic is 1,370 single-unit trucks with two single axles and 277 tractor semi-trailer trucks with single, tandem, and triple axles. The axle weights are: cars: two (one front, one back) 2000-lb single axles single-unit truck: 8000-lb, single axle (front), 22,000-lb, single axle (back) tractor semi-trailer truck: 10,000-lb single axle, 16,000-lb tandem axle, 44,000- lb triple axle Calculate the 18-kip equivalent single axle load for the total traffic over the design period. (round your answer to the nearest whole number)

traffic is 28,753, and the daily truck traffic is 1,370 single-unit trucks with two
single axles and 277 tractor semi-trailer trucks with single, tandem, and triple
axles. The axle weights are:
cars: two (one front, one back) 2000-lb single axles
single-unit truck: 8000-lb, single axle (front), 22,000-lb, single axle (back)
tractor semi-trailer truck: 10,000-lb single axle, 16,000-lb tandem axle, 44,000-
lb triple axle
Calculate the 18-kip equivalent single axle load for the total traffic over the
design period.
