Introduction

Rigid pavements are rigid i.e, they do not flex much under loading like flexible pavements.
They are constructed using cement concrete. In this case, the load carrying capacity is mainly due to the
rigidity ad high modulus of elasticity of the slab (slab action). H. M. Westergaard is considered the pioneer inproviding the rational treatment of the rigid pavement analysis.

In rigid pavements, wheel loads are transferred to sub-grade soil by flexural strength of the pavement and the pavement acts like a rigid plate (e.g. cement concrete roads). In addition to these, composite pavements are also available. A thin layer of flexible pavement over rigid pavement is an ideal pavement with most desirable characteristics. However, such pavements are rarely used in new construction because of high cost and complex analysis required.

Further in this course we will see the different design philosophy, and method of pavement design, also concern on the Defect and Failure of Rigid pavement.
