A common passenger car has two single axles with 2-kip load on each. A truck has tandem axles and one single axle. The tandem axles carry 48-kip load on each axle. The single axle of the truck carries 14 kip. If SN=5, P= 2.5, how many passenger cars produce the equivalent damage of one truck on flexible pavement?
