A rigid pavement is designed with an 11-inch slab thickness, 90% Relliability (Zr = -1.282), Es = 4 million psi, modulus of rupture of 600 psi, modulus of subgrade reaction of 150 lb/in³, a 2.8 load transfer coefficient, initial PSI = 4.8, final PSI of 2.5, overall standard deviation of 0.35, and a drainage coefficient of 0.80. The pavement has a 20-year design life. The pavement has three lanes in one direction (PDL = 0.80) and is conservatively designed for trucks that have one 20,000-lb single ade load (1.58), one 26,000-lb tandem ade (0.619), and one 34,000-lb triple axde (0.593).

Question
Transcribed Image Text:A rigid pavement is designed with an 11-inch slab thickness, 90% Rellability (ZR = -1.282), Es = 4 million psi, modulus of
rupture of 600 psi, modulus of subgrade reaction of 150 lb/in?, a 2.8 load transfer coefficient, initial PSI = 4.8, final PSI of
2.5, overall standard deviation of 0.35, and a drainage coefficient of 0.80. The pavement has a 20-year design life. The
pavement has three lanes in one direction (PDL = 0.80) and is conservatively designed for trucks that have one 20,000-lb
single axle load (1.58), one 26,000-lb tandem axle (0.619), and one 34,000-b triple axle (0.593). What is the daily
estimated truck traffic on the three lanes?
