rigid and flexible pavement
A rigid pavement is on a highway with two lanesin one direction, and the pavement is conservativelydesigned. The pavement has an 11-inch slab with amodulus of elasticity of 5,000,000 lb/in2 and a concretemodulus of rupture of 700 lb/in2, and it is on a soil witha CBR of 25. The design drainage coefficient is 1.0, theoverall standard deviation is 0.3, and the load transfercoefficient is 3.0. The pavement was designed to last 20years (initial PSI of 4.7 and a final PSI...

4.27 A rigid pavement on a multilane highway (two lanes each direction) has been conservatively designed (for its design-lane traffic). The pavement engineer uses an 11-inch slab, Ec of 4 x 106 lb/in2, a concrete modulus of rupture of 695 Ib/in2 a load transfer coefficient of 2.8, an initial present serviceability index of 4.2, and a terminal serviceability index of 2.5. The overall standard deviation is 0.6, the subgrade CBR is 20, and the drainage coefficient is 1.0. The pavement...
rigid and flexible pavement
A three-lane northbound section of interstate (withthe design lane conservatively designed) has rigidpavement (PCC) and was designed with a 10-inch slab,90% reliability, 700 lb/in2 concrete modulus of rupture,4.5 million lb/in2 modulus of elasticity, 3.0 load transfercoefficient, and an overall standard deviation of 0.35.The initial PSI is 4.6 and the TSI is 2.5. The CBR is 2with a drainage coefficient of 1.0. The road wasdesigned exclusively for trucks that have one 24-kiptandem axle and one 12-kip single axle. It is knownfrom...

2- A roadway design company is designing a rigid pavement for a four-lane northbound section of interstate. This pavement was designed with an 8-inch slab, 95% reliability, a 800 lb/in2 concrete modulus of rupture, a 5 million lb/in2 modulus of elasticity, a 3.0 load transfer coefficient, and an overall standard deviation of 0.25. The initial PSI is 4.6 and the TSI is 2.5. The pavement was conservatively designed (assuming the upper limit of the W18 design lane load) to last...
