What is a rigid pavement

Rigid pavements are subjected to significant stresses as a result of temperature variations.A rigid pavement is constructed with portland cement concrete (pcc) and aggregates, as with flexible pavements, the subgrade (the lower layer) is often scarified, blended, and compacted to maximum density.Rigid pavements support loads through rigidity and high modulus of elasticity of concrete slab.Longitudinal joints are still used.Load is transmitted through the slabs to the underlying subgrade by flexure of the slabs.

The load is distributed from top to bottom upto subgrade.Rigid pavements are generally made of portland cement concrete hence known as 'cc pavement'.Jointed plain concrete pavement (jpcp),Further, these pavements can have reinforcing steel, which is generally used to reduce or eliminate joints.There are two main types of road construction.

A rigid pavement can be defined as a pavement layer include of a combination of aggregates and cement, it is blended precisely and then put and compacted on a bed of.Rigid pavement and flexible pavement.It is simply a concrete road (either rcc or pcc).So, these are the major difference.The number of esals a rigid pavement can carry over its lifetime is very sensitive to slab depth.

Flexible pavement and rigid pavement.May be utilized with justifications.In rigid pavements, the stresses.In india, there are two types of pavements:Rigid pavements on the other hand, are made from cement concrete or reinforced concrete slabs, laid over a low strength concrete layer (dry.
