Design of pavements

Pavement is a structure that is made up of different layers such as sub-base course layer, base course layer, binder course, and a surface course formed with different materials such as gravel, above the subgrade soil constructed to act as a path or carriageway enabling the movement of vehicles. The surface of the pavement should possess characteristics such as adequate friction, light reflection, and drainage. The pavements are classified based on structural design into rigid pavements, flexible pavements, composite pavements, and unpaved pavements. The process of determining a suitable pavement type, its constituent layers, and its thickness is called pavement design.

Problem 20.2 Concrete has a notable capacity against compression stresses but very little capacity against tension stresses (it cracks easily). One strategy to counteract this weakness in tension involves using wires or rods to prestress the concrete beam in regions where flexural tension can be anticipated. Consider the simply-supported beam shown, which has a rectangular cross section of 18" x 12". If concrete has specific weight of 150 pcf (pounds per cubic foot) determine the required tension in rod AB, which runs through the beam so that no tensile stress is developed in the concrete at its center section a-a. Neglect the size of the rod and any deflection of the beam. a 16 in. B 2 in. 18 in. 6 in. 6 in. -4 ft- - 4 ft Tip: the beam's self-weight causes and internal moment at the midspan section and therefore flexural tension stress at the bottom of the beam. When the rod is tensioned it applies both an axial stress and a bending moment (since it is applied eccentrically on the…
