Arigid pavement is designed with an 11-inch slab thickness, 90% reliability, = 4 million lb/in2 , modulus of rupture of 600 lb/in2 , modulus of subgrade reaction of 150 lb/in3 , a 2.8 load transfer coefficient, initial psi = 4.8, tsi = 2.5, overall standard deviation of 0.35, and a drainage coefficient of 0.8. the pavement has a 20-year design life. the pavement has three lanes and is conservatively designed for trucks that have one 20,000-lb single axle, one 26,000-lb tandem axle, and one 34,000-lb triple axle. what is the estimated directional daily truck traffic?
