What is a flexible pavement in PDF?
A flexible pavement is defined as a pavement having little or no inherent resis- tance to deformation under applied load Failure of such a pavement is assumed to. be the result of excessive deflection of the subgrade which causes the pavement to..
What is a flexible pavement in PDF?
Flexible pavements are constructed of several thicknesses of asphalt or bituminous concrete layers overlying a base of granular material on a prepared subgrade.
They spread the concentrated aircraft wheel loads throughout their depth until the load at the base of the pavement is less than….
What is the construction method of flexible pavement?
In flexible road construction, one or more layers of selected granular material are laid and compacted over the subgrade.
As-dug, naturally occurring materials are often used, but greater performance is gained by using manufactured, crushed aggregates..
What is the process of flexible pavement road construction?
A flexible pavement is defined as a pavement having little or no inherent resis- tance to deformation under applied load Failure of such a pavement is assumed to. be the result of excessive deflection of the subgrade which causes the pavement to..
What materials are used to construct flexible pavement?
Design method such as CBR, GI, IRC, Bermister layer method.
From this method, we can determine the thickness of flexible pavement by using GI, CBR, and IRC method.
Flexible pavements are those which are surfaced with bituminous (or asphalt) materials..

Here are the general steps involved in the construction of rigid pavement:
- Preparing the Subgrade.
This is the first step in the construction of rigid pavement.- Provision of Subbase Course
- Preparation of Base Course
- Preparation of Surface Course
- The CBR test is a penetration test in which a standard piston, with a diameter of 50 mm is used to penetrate the soil at a standard rate of 1.25 mm/minute.
Although the force rises with the depth of penetration, in many cases, it does not increase as quickly as it does for the standard crushed rock, so the ratio falls.
