Flexible pavements design
Original language description
Nowadays is essential a appropriate pavement design and one of the most used are flexible pavements. These kind of road have different layers, where deformation are formed due to the load that have to withstand. These deformation can be recover or permanent. And here is when the concept of resilience module appears. This module is related to the process of repeated load. Under the moving load the permanent deformation is accumulated and in the intermediate cycles, the permanent deformation for each cycle is decreased until it almost disappear in the final cycles. In this moment the sample arrive thus a state which all deformation is recoverable and this is the moment where it have a resilience performance. The module can be measured with different tests. One of the most frequently test is the CBR, but is not exact, so one of the best method is a cyclic triaxial test. It is a complicated and expensive method, so that why nowadays are investigating other methods such as finite element.
