2 Types of Pavement You Can Choose From

A pavement is an important component in every structure. This is necessary for the safety of everybody who goes in and out of the house driving their vehicles. When it comes to the consideration of the design, there are two types to choose from. The south Florida pavers offer rigid pavement ad flexible pavement.  


The difference between the two is how the loads are distributed to the subgrade. If you want to know more about the types of pavements, read more.  

Rigid Pavements 

A rigid pavement is constructed from reinforced concrete slabs or cement concrete. The rigid concrete has also a category of semi-rigid pavements, which the grouted concrete roads belonged to. This type of pavement aims to provide a sufficient strength to resist the weight and load of the vehicle traffic. The materials used in this construction are structural cement concrete slabs. Its elasticity and rigidity is distributed over the soil.  

When designing this type of pavement, the top thing to be considered is the flexural strength of the concrete. Because of this design, when the subgrade deflects, the concrete is also to bridge over the areas which have inadequate support and areas with local failures.  

Flexible Pavement 

The materials used in constructing the flexible pavement are aggregates and asphaltic materials. The mixture is placed on a bed of compacted granular material over the subgrade. The examples of flexible pavements are stabilized soil roads and bound macadam roads.  

In the design of this pavement, a main principle is used. It should be that the load’s intensity will diminish once the load is transmitted downwards by spreading the load in a larger area. The load is carried deep down through the layers of the granular materials. When constructing such pavements, the grading is used. The strongest material is near the surface.  

Side-by-Side Comparison 

To understand more about the two, let’s have a side-by-side comparison. The flexible pavement has series of layers of materials, with the weakest at the bottom and the strongest at the surface. The rigid pavement has only one layer of concrete slab. The flexible pavement can reflect deformations on the surface, but the rigid pavement bridges over the areas with weak support.  

The stability of the flexible pavement highly depends on the particle friction, aggregate interlock and cohesion. The rigid pavement’s stability on the other hand is provided by the pavement slab. One thing that can affect the construction of flexible pavement is the subgrade strength, while the rigid pavement depends on the strength of the concrete.  

The flexible pavement works by distributing the load of the traffic through its component layers, while the rigid pavement distributes the load over the subgrade’s wide area. The good thing about flexible pavement is that the temperature and atmospheric conditions can’t stress it out, but the temperature changes can greatly affect the rigid pavements.  

Finally, the flexible pavement has a self-healing property and deformations because of heavy wheel loads are recoverable, but the rigid pavements cannot be recovered.
