Abstract:
One of the major challenges facing pavement engineers is how to select the optimal repair strategy for a flexible pavement that is aging and exhibiting distress. This selection process can be relatively straightforward if the cause of the pavement distress is known. Unfortunately, finding the cause of the distress is often complex.
For example, with the alligator cracking, shown in Figure 1, the cause could be related to defects in any of the pavement layers. If the cause is confined to the upper layers, then the repair can be relatively inexpensive; however, if the problems are related to structural deficiencies in the base or subgrade, then much more extensive and expensive repairs will be required.
