ADVANTAGES AND DISADVANTAGES OF RIGID PAVEMENT

In this article, we will discuss about various ADVANTAGES AND DISADVANTAGES OF RIGID PAVEMENT. There are also some requirements for the construction of rigid pavement and we will discuss that also in this article.

ADVANTAGES AND DISADVANTAGES OF RIGID PAVEMENT


Rigid pavement:

The rigid pavement is usually provided reinforcement about
50mm below the surface of the pavement which consists of woven wire, wire mats, expanded metal etc. Its major function is to strength the slab but to hold together the crack that form, to control their development and thus add the aesthetic of the road surface.


A rigid pavement consists of concrete slab which may or may not
be reinforced. Under favorable conditions, special preparation of the sub-base is not required and the slabs are laid directly on the properly finished subgrade. According to AASHTO, the subgrade or sub-base layer whatever underlies the concrete wearing slab must confirm to the following requirement:

Requirements for Rigid Pavements:

  • No soft spots are present in the subgrade or sub-base.
  • The base or sub-base extends to at least 30cm wider on either sides of the width to be concreted.
  • The subgrade is properly drained.

Advantages of Rigid Pavement:

  •  It is very easy to clean and practically dust free.
  • The resistance to traffic is low.
  • When clean, it is not slippery.
  • When properly designed and constructed, it has long life and comparatively low maintenance cost.
  • It can withstand any amount of traffic.

Disadvantages of Rigid Pavement:

  •      It has high initial cost.
  •      It requires skilled personnel and cautious handling of the material.

I hope that this article will help you to understand about various ADVANTAGES AND DISADVANTAGES OF RIGID PAVEMENT.
