In 1996, a rigid pavement on a northbound section of interstate highway was designed with a 12-inch PCC slab, an Ec of 6x10^6 lb/in^2, a concrete modulus of rupture of 800 lb/in^2, a load transfer coefficient of 3.0, an initial PSI of 4.5, and a terminal serviceability index of 2.5. The overall standard deviation was 0.45, the modulus of subgrade reaction was 190 lb/in^3, and a reliability of 95% was used along with a drainage coefficient of 1.0. The pavement was designed for a 10-year life, and traffic was assumed to be composed entirely of tractor semi-trailer trucks with one 16-kip single axle, one 20-kip single axle, and one 35-kip tandem axle (the effect of all other vehicles was ignored). The interstate has four northbound lanes and was conservatively designed. How many tractor semi-trailer trucks, per day, were assumed to be traveling in the northbound direction

In 1996, a rigid pavement on a northbound section of interstate highway was designed with a 12-inch PCC slab, an Ec of 6x10^6 lb/in^2, a concrete modulus of rupture of 800 lb/in^2, a load transfer coefficient of 3.0, an initial PSI of 4.5, and a terminal serviceability index of 2.5. The overall standard deviation was 0.45, the modulus of subgrade reaction was 190 lb/in^3, and a reliability of 95% was used along with a drainage coefficient of 1.0. The pavement was designed for a 10-year life, and traffic was assumed to be composed entirely of tractor semi-trailer trucks with one 16-kip single axle, one 20-kip single axle, and one 35-kip tandem axle (the effect of all other vehicles was ignored). The interstate has four northbound lanes and was conservatively designed. How many tractor semi-trailer trucks, per day, were assumed to be traveling in the northbound direction?
