Rigid pavement is designed and analyzed by using the elastic theory. Advantages of Rigid Pavement. Rigid lasts much, much longer i.e 30+ years compared to 5-10 years of flexible pavements. In the long run it is about half the cost to install and maintain. But the initial costs are somewhat high.
Flexible and Rigid Pavement Any ground surface that you can step on which carries a considerable amount of weight or load is called a pavement. Pavements are primarily constructed for use by vehicles and pedestrians, transferring the load from the upper surface to the natural soil.

Natural stones have been typically used as a paving material in historically conserved areas due to architectural aesthetic aspect and environmental impact. However, they have been traditionally suggested in light traffic volume due to the defects caused by the increased traffic loading and volume. The failures can lead to diverse problems such as losing flatness, severe damage to both ...
Sep 09, 2020· Rigid Pavement. Rigid pavements are generally more expensive and difficult to install and maintain. They're made out of a cement concrete with a base and sub base. Unlike flexible pavement, rigid pavements have a high flexural strength, making every layer virtually immune to bending under pressure.

Rigid pavements – Cement concrete pavements can get affected by temperature gradients between the top and bottom faces. The phenomenon of 'warping' causes temperature stresses in the body of the pavements, which combines with the stresses caused by traffic loads. These combined stresses have to be within the limits of allowable values.
