4.12 You have been asked to design the pavement

for an access highway to a major truck terminal. The

design daily truck traffic consists of the following: 80

single axles at 22,500 lb each, 570 tandem axles at

25,000 lb each, 50 tandem axles at 39,000 lb each,

and 80 triple axles at 48,000 lb each. The highway is

to be designed with rigid pavement having a modulus

of rupture of 600 lb/in² and a modulus of elasticity of

5 million lb/in². The reliability is to be 95%, the

overall standard deviation is 0.4, the drainage

coefficient is 0.9, APSI is 1.7 (with a TSI of 2.5), and

the load transfer coefficient is 3.2. The modulus of
