Construction of reinforced concrete roadways
Three prestressing systems are described, namely, fixed system in which concrete is longitudinally prestressed by means of jacks placed in so-called active joints, mobile system with external prestress in which effects of thermal and hygrometric variations are compensated by elastic joints (metallic or pneumatic) inserted between successive slabs and, finally, mobile system with internal prestress in which independent single slabs are prestressed by wires, rods, or cables; advantages and drawback of these systems are discussed.
