Quick Summary

Rigid pavement is a durable surfacing for roads and other areas, primarily made of concrete. Its main purpose is to transfer loads to the sub-base and underlying soil. Concrete is composed of coarse and fine aggregate mixed with portland cement, and it is typically reinforced with steel rods or mesh. Unlike flexible pavements, which use bituminous materials like asphalt, rigid pavements are characterized by their concrete structure. The concrete slab can range from 6 to 14 inches thick and is laid by a paving machine. Cracking is managed through steel reinforcement or transverse joints to enhance tensile strength and ensure fine, uniform cracking.12

…are called either flexible or rigid, according to their relative flexural stiffness. Flexible pavements (see figure, left) have base courses of broken stone pieces either compacted into place in the style of McAdam or glued together with bitumen to form asphalt. In order to maintain workability, the stones are usually…

Rigid pavements are constructed of portland cement concrete slabs resting on a prepared subbase of granular material or directly on a granular subgrade. Load is transmitted through the slabs to the underlying subgrade by flexure of the slabs. Flexible pavements are constructed of several thicknesses…
