Give me right solution... Urgent please A 5 tonne wheel load is applied on a pavement and generates a surface deflection of 0.15 mm. A. If the pavement is 125 mm thick, what is the vertical stress at the top of the subgrade? B. If the equivalent radius of tyre contact is 100 mm and Poisson’s ratio is 0.3, what is the pavement’s modulus of elasticity
A rigid pavement is to be used to carry a wheel load of 50.93 kN. Enough dowels will be used across the joint. What will be the difference in thickness (in mm) between the edge and the center of the pavement? The allowable tensile strength of concrete is 1.39 MPa.
A rigid pavement is to be used to carry a wheel load of 58.77 kN. Enough dowels will be used across the joint. The allowable tensile strength of concrete is 1.45 MPa. Thus, what will be the difference in thickness (in mm) between the edge and the center of the pavement?

A rigid pavement has a wheel load capacity of 53.96 kN. The allowable tensile stress of concrete is 1.37 MPa. Determine the thickness (cm) of the pavement if dowels are negligible. Express your answer in 1 decimal place.
Problem No. 1A flexible pavement for an urban interstate highway is to be designed using the AASHTO method to carry a design ESAL of 3 x 106. It is estimated that it takes about a week for water to be drained from within the pavement and the pavement structure will be exposed to moisture levels approaching saturation for 30% of the time. The following additional information is available: Elastic modulus of asphalt concrete = 450,000 psiResilient modulus of base material = 35,000 psiResilient modulus of subbase material = 15,000 psiCBR of subgrade material = 8

Question 18 A rigid pavement has a wheel load capacity of 53.96 kN. The allowable tensile stress of concrete is 1.37 MPa. Determine the thickness (cm) of the pavement if dowels are negligible. Express your answer in 1 decimal place.
A rigid pavement is to be used to carry a wheel load of 59.35 kN. Enough dowels will be used across the joint. What will be the difference in thickness (in mm) between the edge and the center of the pavement? The allowable tensile strength of concrete is 1.47 MPa. Round off the nearest whole number.
. Say what is the main purpose of the pavement or pavement layers, and then draw the flexible pavement layers respectively.
The following figure shows concrete pavement with the layer thickness and elastic modulus as indicated. Assume modulus of rupture of 650 psi, load transfer coefficient of 3.2, serviceability loss from 4.5 to 2.5, and drainage coefficient of 0.9. The bedrock depth and loss of support is not considered for the subgrade. Use the design equation or monograph with 50% reliability to solve the following: 1) Determine the number of ESAL that the pavement can carry before failure. 2) If the daily traffic has 1080 single axles (20-kip), 400 single axles (24-kip), and 680 tandem axles (40-kip), and the annul traffic is the same over the design period, how many years would the concrete pavement last before failure? 8-inch Portland Cement Concrete Ec=4×106 psi 8-inch Granular Subbase Ec=30,000 psi Subgrade Mr = 5000 psi
