Challenge Problems
Push your limits with challenges.
Question 1
A pavement with a joint width of 3.5 cm requires dowel bars that can carry a total load of 7500 kg. If you are using a dowel bar of diameter 3 cm, calculate the required embedment length using the given equations.
💡 Hint: Use the relationships among shear, bending, and bearing stresses.
Question 2
Design dowel bars for a concrete pavement with a thickness of 30 cm, a wheel load of 6000 kg, and a radius of relative stiffness of 90 cm. Determine the spacing based on a joint width of 2.5 cm.
💡 Hint: Remember the effective distance of load transfer is critical.
