What is a Fully Flexible Pavement?


A fully flexible asphalt pavement normally consists of one or two layers of a base course product dependent on the Million standard Axile (MSA) required for the road. On top of the base layer is a binder course material with a surface course product as the traffic running layer as the final layer. The asphalt pavement is supported by a foundation layer, which is either Class 1, 2 and depends on the MSA requirement, which can be made up of either a subbase (Type 1), capping material, HBM (Hydraulically Bound mixture - CBGM), Stabilisation or the existing ground. Underneath the foundation can be either the existing ground or compacted soil.

Flexible pavements can be selected over rigid concrete roads because of performance benefits including the fact that they can be strengthened and improved in stages with the growth of traffic also they are often less expensive in the initial cost and maintenance.

Flexible pavement benefits

With flexible pavement, the subgrade beneath is less likely to deform than with rigid pavement.


Repairs are easy and inexpensive with flexible pavement.


The installation process does not require joints and materials can be cheaper.
